E3H2

Miniature photoelectric sensors in M8 and M12 housings

For object detection applications where space is crucial, the E3H2 provides the easy mounting of cylindrical sensors in small M8 and M12 metal housings.

  • M8 or M12 sized cylindrical housings when mounting space is crucial
  • Retro-reflective models with two teaching modes for standard and semi-transparent objects
  • Diffuse reflective models with fixed and teachable sensing distance 
  • Pre-wired and connector models
