Monarch Remote Optical Sensor (ROS-W)

Remote Optical Sensor (ROS) with cable 1-250,000 RPM. The most versatile and popular sensors we make. The ROS-W (Remote Optical Sensor with tinned wire termination) and ROS-P (Remote Optical Sensor with 1/8" phone plug termination) are threaded stainless steel remote optical sensors with a visible red LED light source. All these sensors have the "on-target" green LED indicator.
