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.
