PROX-MICRO Inductive Proximity Switch

Micro-controlled, Field-adjustable, Multi-setpoint Speed Monitor

The PROX-MICRO Proximity Switch is a non-contacting speed sensing device which converts pulses from a ferrous target to an electrical signal. The speed monitor utilizes a microcontroller and proprietary internal software to precisely monitor the RPM rate of the rotating ferrous target(s). Time between pulses is compared to application-appropriate, user-defined settings. It is packaged in a NEMA 4/5 enclosure with a transparent Lexan™ cover for dust and moisture protection.

The PROX-MICRO Proximity Switch is ideal for applications where access is limited such as small or tight locations, as well as high temperature or high vibration installations while providing a remote placement of the controller for easier user access.
