Sensor for Iron & Steel IndustryClose Crane Warning

Laser type Distance Sensor
Max. detecting distance, 20m!
2 pcs of optional distance can be set!

This equipment is composed of the amplifier unit and the reflector. It detects when crane or AGV etc. is close. It measures the distance between the unit and the reflector with phase-difference and executes output. Trouble output ( FAULT) executes when light-emitting amount or light- receiving amount is getting lower or troubled.



-> It is easy to set optional detecting distance by pushing the button for distance setting.
-> It always makes a self-diagnosis with inner circuit and it prevent the troubles beforehand.
-> It is easy to make an optical axis with 5-point level meter.
