MCS-655
Photo-Reflective Speed Sensor
The MCS-655 is now available as 2 Models:
MCS-655M - Retro-Reflective Speed Sensor with Metal Housing
MCS-655P - Retro-Reflective Speed Sensor with Plastic Housing
The MCS-655M is a photo-reflective NPN open collector photo sensor with Light/Dark activated output that operates up to 1000 Hz. For simplified installation purposes the integral LED aids in the MCS-655M model comes in a robust metal housing with a connection cable, LED status indicator, sensitivity control and mounting nuts.
- Switching frequency: 1,000 Hz with light/dark ratio 1:1
- LED is mounted in the back of the unit with sensitivity adjustment
- M18 Threaded body housing with two lock (jam) nuts for easy mounting and positioning
