OGE500 IFM Through-Beam Sensor Receiver OGE-FPKG/US100

IFM OGE500 — Through-Beam Photoelectric Sensor Receiver

The IFM OGE500, identified by type designation OGE-FPKG/US100, is a threaded through-beam photoelectric sensor receiver for industrial automation. It receives the red-light beam from a compatible transmitter and changes its PNP switching output according to the configured light-on or dark-on operating mode.

With an M18 × 1 threaded housing, a detection range specified as less than 25 m, a switching frequency of up to 1,000 Hz, and IP67 protection, this receiver is suitable for presence detection and object monitoring on factory equipment. Correct operation depends on transmitter compatibility, optical alignment, target conditions, and the selected output logic.

01 | Operating Principle: What the Receiver Detects

A through-beam sensor system uses a separate transmitter and receiver mounted opposite each other. The transmitter sends a light beam across the detection path. When an object interrupts the beam, the receiver detects the change and switches its output according to the selected operating mode.

• Detection method: Through-beam photoelectric sensing
• Device role: Receiver
• Light source: Red light, 624 nm
• Specified range: Less than 25 m
• Output type: PNP switching output
• Output logic: Programmable light-on or dark-on
• Factory output setting: Dark-on mode

Because the transmitter and receiver are separate devices, the receiver should not be treated as a standalone reflective sensor. Confirm that the transmitter's optical characteristics and installation arrangement are compatible with the OGE500 before commissioning.

02 | Electrical Performance and Switching Limits

Supply and current consumption

• Operating voltage: 10–36 V DC
• Current consumption: 11 mA
• Protection class: II
• Reverse polarity protection: Yes

Switching output

• Electrical design: PNP
• Maximum DC output voltage drop: 2.5 V
• Continuous output current rating: 150 mA
• Higher current rating condition: 200 mA at 60 °C, as specified
• DC switching frequency: 1,000 Hz
• Short-circuit protection: Yes, pulsed
• Overload protection: Yes

The PNP output is generally used with compatible PLC digital inputs or control interfaces designed for PNP sensor signals. Before connecting the receiver, check the PLC input type, common-potential arrangement, load current, and input switching thresholds. Do not use the output current rating as a substitute for verifying the electrical requirements of the connected device.

03 | Mechanical Design and Environmental Resistance

• Housing style: Threaded
• Thread size: M18 × 1
• Overall length: 72 mm
• Weight: 50 g
• Housing materials: Stainless steel 316L / 1.4404, PA, LCP, EPDM, and TPU
• Front lens material: PMMA
• Operating temperature: -25 to +80 °C
• Ingress protection: IP67
• Switching status indicator: One yellow LED
• EMC standard: EN 60947-5-2
• Specified MTTF: 786 years

The IP67 rating indicates protection under defined ingress testing conditions; it does not mean that the device is suitable for every chemical, washdown process, or continuous immersion application. Check material compatibility and the installation requirements of the actual production environment.

04 | Application Fit: Equipment and Process Scenarios

The OGE500 can be considered for equipment that needs reliable beam-interruption detection, provided the transmitter, mounting arrangement, and PLC interface are compatible.

• Conveyor systems: Detect product presence or gaps as packages pass through a fixed sensing point.
• Packaging machinery: Monitor product transfer, part passage, or interruptions in a controlled optical path.
• Assembly lines: Confirm the presence of components before a subsequent machine operation.
• Material handling equipment: Detect objects crossing a defined path where suitable mounting positions are available on opposite sides.
• Automated production stations: Provide a discrete sensor signal for PLC sequencing, interlocks, or process monitoring.

For fast-moving objects, evaluate the 1,000 Hz switching frequency alongside PLC input filtering, scan time, object size, and the duration of beam interruption. The sensor's switching frequency alone does not establish the maximum reliable machine cycle rate.

05 | Installation and Commissioning: Practical Checks

1. Verify the pair: Confirm the transmitter is compatible with the OGE500 receiver and that the optical path is within the specified application range.
2. Align the optical axes: Mount the transmitter and receiver facing each other. Adjust their positions to obtain a stable received beam before securing the mounting hardware.
3. Confirm the supply: Measure the DC voltage at the sensor terminals under operating conditions. Keep the supply within 10–36 V DC.
4. Check the PNP interface: Confirm the PLC input accepts a PNP signal and that the wiring, common connection, and input threshold are correct.
5. Select the correct output logic: The factory setting is dark-on. Confirm whether the application requires the output to switch when the beam is interrupted or when the beam is received, and configure the mode accordingly.
6. Test the complete sequence: Interrupt and restore the beam while monitoring the yellow LED, PLC input state, and machine response.
7. Secure and protect the installation: Tighten the mounting arrangement appropriately, route the cable or connector away from mechanical damage, and verify sealing after installation.

Do not assume that the yellow LED alone confirms correct PLC operation. The LED indicates sensor switching status; the PLC input, wiring, and control logic must also be checked during commissioning.

06 | Fault Diagnosis: Symptom-Based Troubleshooting

Symptom: The receiver does not switch.

• Measure the supply voltage at the sensor.
• Check transmitter power and confirm that the transmitter is operating.
• Inspect optical alignment, obstructions, and contamination on the front lens.
• Verify the selected light-on/dark-on mode and observe the yellow status LED.

Symptom: The PLC input remains OFF although the sensor appears to detect the beam.

• Confirm the PLC input type is compatible with a PNP output.
• Check connector pin assignments, wiring continuity, and the common-potential connection.
• Measure the switching output voltage and compare it with the PLC input's ON threshold.
• Review PLC input filtering and channel configuration.

Symptom: The output changes intermittently.

• Check whether the transmitter and receiver move or vibrate during machine operation.
• Inspect for temporary beam obstruction, misalignment, or lens contamination.
• Verify that the supply voltage remains stable when other loads switch.
• Review the object's speed and interruption time relative to the machine's sampling and input-filter settings.

Symptom: The sensor works during testing but fails after installation.

• Check whether the mounting bracket or machine structure shifts the optical alignment.
• Inspect the M12 connector for incomplete engagement, damaged contacts, or moisture ingress.
• Confirm that the operating temperature and environmental conditions remain within the specified limits.
• Test the sensor with the actual transmitter and PLC input rather than relying only on an unloaded bench test.

Diagnostic limitation: The supplied specifications identify a switching-status LED and electrical protection functions, but do not specify a comprehensive diagnostic code system. Use measured supply and output values, LED status, alignment checks, and PLC input monitoring to isolate the fault. Do not infer a specific internal failure without supporting measurements.

07 | Selection Guide: Confirm These Details Before Ordering

• Exact designation: Verify OGE500 and type designation OGE-FPKG/US100 against the existing label or equipment documentation.
• Device role: Confirm that the required part is the receiver, not the corresponding transmitter.
• Optical compatibility: Check the transmitter type, beam arrangement, and required sensing distance.
• Output compatibility: Confirm PNP input compatibility and the required light-on/dark-on behavior.
• Mechanical fit: Check the M18 × 1 thread, 72 mm length, available mounting space, and connector clearance.
• Environmental suitability: Compare the operating temperature, ingress protection, and housing materials with the installation conditions.
• Connection details: The specified connection is one 4-contact M12 connector, A-coded. Verify the required pinout using the applicable wiring documentation before energizing.

Ordering note: The product information lists two lock nuts as supplied accessories and a package quantity of one piece. Confirm the actual supply contents and exact variant when requesting a quotation.

08 | Global PLC Spare HUB Review

For a through-beam sensor receiver, the most useful troubleshooting approach is to verify the complete optical and electrical path before replacing the device. In conveyor and packaging applications, intermittent detection is often worth investigating at the alignment, mounting, lens condition, and PLC input-filtering stages first. These checks help distinguish a receiver problem from an installation or control-interface issue.

When replacing an existing unit, matching the OGE500 designation alone is not enough if the transmitter, output logic, connector wiring, or mounting arrangement differs. Confirm the receiver's PNP interface, factory dark-on setting, M18 × 1 mounting, and compatible transmitter before commissioning the replacement.

10 | Frequently Asked Questions

Q1: Can the OGE500 receiver be used by itself to detect an object?

No. It is the receiver in a through-beam sensing arrangement and requires a compatible transmitter to create the optical path. If a single sensor must detect objects without a separate transmitter, evaluate whether a suitable diffuse-reflective or retro-reflective sensor is more appropriate.

Q2: How should the output mode be selected for a conveyor stop function?

Start by defining the required PLC input state when the beam is clear and when an object blocks it. The OGE500 is factory-set to dark-on mode, but the required logic depends on the control design. Verify the sensor's actual switching behavior and the PLC sequence during commissioning. Do not use the sensor's normal switching behavior as the sole safety function for personnel protection.

Q3: Is the stated MTTF of 786 years the same as a guaranteed service life?

No. MTTF is a statistical reliability measure under defined assumptions; it is not a promise that an individual sensor will operate for that period. Actual service life depends on installation conditions, electrical loading, environmental exposure, and maintenance practices.

Q4: What should be checked when replacing a sensor from another manufacturer?

Compare the sensing principle, transmitter compatibility, PNP or NPN output, light-on/dark-on logic, supply range, switching frequency, connector pinout, mounting dimensions, and environmental requirements. Similar housing dimensions do not guarantee electrical or optical compatibility.

Q5: How can I determine whether the sensor is suitable for a high-speed production line?

Compare the maximum expected object passage rate and beam interruption duration with the sensor's 1,000 Hz switching frequency. Then include PLC input filtering, controller scan behavior, and the machine's response requirements in the evaluation. Conduct a test using the actual product, mounting geometry, and control system before approving the installation.
