Dual Output Measurement Universal Light Curtain Sensor GM20-20J
Features and Applications
1. Applicable for the safety detection of automatic assembly line, elevator, danger restricted zone, metal forming machine, punching & shearing machine tool, paper cutter and so on and has protection function.
2 .Adopting synchronism scanning technology, concentrated beam path, non working blind area, strong anti-interference ability, and convenient installation.
3. Resistance to mutual interference function. It is possible to closely mount more than 2 sets of devices.
4. Fault self-check, function, power failure stop, inner component fault stop, connection fault stop, object invading stop signal output.
5. Attached with specific control supplying powerful control function.
