Microwave Sensor for Crane Proximity Detection

Microwave Sensor for Crane Crash Avoidance MICRO-ROBO®
MWS-CAS-2A15/B15 PAT.

The MWS-CAS-2A15/B15 Micro-Robo is a microwave sensor developed specifically for use on overhead cranes as a crash avoidance sensor.
The sensors are installed face-to-face on adjacent overhead cranes running on the same rails. When one crane approaches the detection area of an adjacent crane, its sensor detects the microwaves transmitted by the sensor mounted on the other crane and an alarm is generated, thus preventing collision.

Features

  • Simple construction The transmitter and receiver are combined in one compact and economical unit.
  • Unaffected by adverse environments Microwaves are generally unaffected by environmental conditions, thus this sensor is unaffected by rain, wind, snow, frost, heavy dust, smoke or vapor.
  • High penetration Easily penetrates dirt and dust accumulation on the antenna, thanks to the high penetrability of microwaves.
  • Three dimensional detection area The sensor has a conical shaped beam pattern, detection occurs when one sensor enters the detecting area of the others. The detecting area can be adjusted by setting the sensitivity.
  • No set-to-set interference Four channels are available, selectable by rotary switch.
    This permits the use of multiple Micro-Robos in close proximity to each other.
  • Power level & sensitivity indicators The received power level and the sensitivity-set-point are indicated on the receiver by a bank of 15 LEDs, allowing for easy visual adjustment and maintenance of the sensors.
  • Enclosure rating IP65 equivalent
