Omron E3T-C DATASHEET
Miniature photoelectric sensors in M5 and M6 sized housing
500 mm
E3T-C
The E3T-C family of miniature
photoelectric sensors is the ideal
solution when mounting space is
crucial.
• axial and radial M5 sized through-beam sensors
• axial M6 sized diffuse-reflective sensors
• pre-wired models in stainless steel housing
