Large Reflective Photoelectric Beam Sensor, 50ft

  • product_icon
  • product_icon
  • Up to 50ft (15m) sensing range
  • Large sensor with patented design and large reflector for a large sensing area and easier alignment
  • Reflective beam provides reliable perimeter security, minimizing false alarms from falling leaves, birds, etc.
  • Lensed optics reinforces beam strength and provides excellent immunity to false alarms due to rain, snow, mist, etc.
  • Response time adjustable from 50~700 ms for nearly all situations
  • NO/NC Alarm output
  • 12~250 VAC/VDC operation
  • Weatherproof (IP55), sunlight-filtering case for indoor and outdoor use
  • Includes large reflector, hoods for sensor and reflector, and mounting hardware

 Typical Applications

  • For garage or overhead doors, outdoor gates
  • Industrial automation: detect objects onmanufacturing line

Product Information Sheet (PI)


Sensor does not detect the object. • Check the sensor’s alignment.
• Readjust the sensor’s response time.
Alarm LED will not turn ON when the beam is interrupted • Clean the sensor and reflector with a damp (not wet) cloth.
• Adjust the reflector and/or sensor for proper alignment.
Alarm LED turns ON when object is detected, but there is no output • Check wiring between the sensor and local alarm device.
Alarm LED is continuously ON • Check the sensor’s alignment.
• Check for any objects between the sensor and reflector that may be causing false alarms.
Alarm output becomes erratic in bad weather • Check the sensor’s alignment.
• Readjust the sensor’s response time.
Frequent false alarms from leaves, birds, or other objects • Readjust the sensor’s response time.
• Change the sensor’s location.
