Industrial Contact Sensor Amplifier

The Keyence GT2-71P is a new contact sensor amplifier built for industrial automation systems. It processes signals from compatible sensor heads to provide reliable detection in manufacturing environments. This unit suits engineers integrating presence or position sensing into existing control architectures.

Installation Notes

The amplifier mounts on standard DIN rail for quick cabinet assembly. Wiring uses screw terminals that accept solid or stranded conductors within the specified gauge range. Incorrect polarity on the supply lines will prevent operation and may damage the internal circuitry.

Sensor Compatibility

This amplifier works exclusively with Keyence GT2 series sensor heads matched to the 71P variant. It does not support other GT2 codes or third-party transducer families. Verify the sensor head model before purchase to avoid a mismatch.

Questions about this item

How do I confirm the GT2-71P amplifier is operating correctly after installation?

Power the unit and verify the output signal changes smoothly when the contact sensor probe touches the target surface.

What ships with the GT2-71P and what must be sourced separately?

The box contains one new Keyence GT2-71P amplifier; the contact sensor probe and mounting hardware are sold separately.

Which GT2-71P variant should I select for my application?

Only the standard GT2-71P model is listed; choose it when you need a single-channel contact sensor amplifier.
