How it works: Instead of being on continuously like our other optical sensors, the LED light source in the ROSM is modulated on and off at a high frequency. That high-frequency light signal is reflected back at the sensor for processing while all other sources of light are filtered out and/or ignored. The ROSM is packaged in a threaded 303 stainless steel tube and has a green LED on-target indicator.

ROSM-P: Modulated Remote Optical Sensor with 8-foot cable, 1/8" (3.5mm) phone plug connector, mounting bracket, and 12 inches of reflective tape.

ROSM-W: Modulated Remote Optical Sensor with 22-foot cable with tinned leads, mounting bracket, and 12 inches of reflective tape.

Longer Cable Models and Bulk Sensor Cable are available for any of our sensors. Please give us a call or email us for pricing.
