Product Description

OMRON FE-61R Fiber Optic Sensor Amplifier

The OMRON FE-61R is a fiber optic sensor amplifier unit designed for use with OMRON’s extensive range of fiber optic sensing heads (sold separately). This amplifier provides reliable object detection in industrial automation environments. It typically features sensitivity adjustment for optimal performance tuning based on the application requirements and the specific fiber unit employed (through-beam or reflective). LED indicators provide visual confirmation of the operating status and detection stability, simplifying setup and maintenance. Designed for integration into control systems, it operates on standard DC voltage.
