Technical Frequently Asked Questions (FAQ)

Why is a flat-ribbon cable preferred for the EL1862 over individual wiring?
It allows for IDC (Insulation Displacement Contact) termination, which eliminates the need for manual wire stripping and reduces installation time by up to 70%.

Can the EL1862 handle ground-switching applications?
Yes, this specific series is available in ground-switching variants, providing flexibility for different sensor circuit designs.

What is the maximum current capacity per pin?
The module supports up to 1 A per connection pin, ensuring compatibility with a wide range of peripheral sensors.

How should I manage cable length to prevent signal degradation?
Ensure your ribbon cable length remains within the EMC compliance limits for your specific cabinet environment, ideally under 3 meters for best signal integrity.

Which wire gauge is required for optimal contact?
The terminal is designed specifically for AWG 28 flat-ribbon cables with a 1.27 mm pitch to ensure a gas-tight IDC connection.
