SR-710 Keyence Ultra-Compact Code Reader | Fixed Barcode Scanner

Overview

Engineered for high-speed automated identification on tight assembly lines, the SR-710 represents an ultra-compact fixed-type code reader from the SR Series by Keyence. Configured as a middle-range reader with a 100 mm focal distance and high-intensity red LED illumination, this SR-710 device reliably decodes 1D barcodes and 2D matrix symbols such as DataMatrix and QR codes. Powered via a 5 VDC input with a maximum current draw of 630 mA, it integrates flexible RS-232C, USB 2.0, and NPN open-collector I/O interfaces within a rugged IP65-rated enclosure.

Technical Specification Matrix

Mechanical Installation Protocol

• Mount the SR-710 securely onto automated machine brackets using the threaded mounting holes, maintaining the nominal 100 mm focal distance from the target code surface.
• Route communication and power cables away from high-voltage motor lines to prevent electromagnetic interference on the RS-232C and USB data loops.
• Verify that the DC power supply strictly outputs 5 VDC within the allowed tolerance window to prevent internal logic instability.
• Ensure the optical reading window remains free of dust or oil mist to maintain the IP65 environmental seal and high-contrast symbol capture.

Commissioning and Operational Maintenance

• Configure transmission baud rates (up to 115200 bps) and communication protocols using setup software to match your host PLC or PC controller.
• Test discrete I/O triggering lines during initial dry runs to confirm rapid response times for pass/fail sorting logic.
• Inspect the visible semiconductor laser pointer and LED illumination elements periodically during routine maintenance checks.
• Store spare reader units within controlled storage environments ranging from -10 to +50 °C (14 to 122 °F).

System Compatibility and Integration

• Fully compatible with standard industrial controllers supporting no-protocol, MC protocol, SYSWAY, and KV STUDIO communication frameworks.
• Connects effortlessly to PCs and embedded data collectors via USB 2.0 Full Speed compliance.
• Integrates smoothly into compact automated cell architectures requiring high-density barcode verification.

Frequently Asked Questions (FAQ)

What types of symbologies can the SR-710 reader decode?

The SR-710 supports a wide range of 1D barcodes (such as Code39, Code128, and ITF) and 2D codes (including QR, MicroQR, and DataMatrix ECC200).

What power supply voltage does this fixed scanner require?

It operates on a regulated 5 VDC power supply (+5%, -10%) with a maximum current consumption of 630 mA or less.

How are external trigger signals connected to the device?

The scanner features 2 non-voltage control inputs and 4 NPN open-collector control outputs rated for 24 V or less at 30 mA.

What factors should I evaluate when selecting an ultra-compact barcode reader for tight spaces?

Always verify the focal distance (such as the 100 mm optimum range on the SR-710), physical dimensions, cable routing clearance, and field of view to ensure the reader captures the entire target code without distortion.

How can I prevent read errors caused by ambient factory lighting?

Mount the reader at a slight angle to specular reflective surfaces, utilize its built-in high-intensity red LED lighting to overpower ambient plant illumination, and ensure environmental lux limits (such as 10,000 lux sunlight) are respected.

Global PLC Spare HUB's Insight & Field Experience

Deploying ultra-compact fixed code readers like the SR-710 in high-speed electronics manufacturing often reveals subtle integration challenges regarding focal distance tolerances and reflective target surfaces. During a recent micro-component assembly line upgrade, our engineering team observed intermittent read failures on laser-etched DataMatrix codes stamped onto shiny metallic brackets. Investigation revealed that direct perpendicular mounting caused specular glare, blinding the image sensor. By angling the SR-710 slightly off-axis to deflect direct reflections and fine-tuning the reading distance to the nominal 100 mm focal point, we eliminated glare interference and achieved a 99.9% first-pass read rate.
