The ROSM Modulated Remote Optical Sensor is designed specifically for use in high ambient light applications where other optical sensors frequently suffer from light interference. The LED light source is modulated, and the light signal is reflected back for processing while all other sources of light are filtered out and/or ignored. 1-20,000 RPM

Detailed Description
The ROSM are versatile Remote Optical Sensors that have a visible red LED light source and green LED On-Target Indicator. The sensors are housed in a threaded 303 stainless steel tube and are built with various length cables terminated with either tinned wires or 1/8″ [3.5 mm] male stereo plug. All models are supplied with a 90° mounting bracket and jam nuts.
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.
