The high durability stainless steel sensing face provides more than 20 times longer protection against mechanical damage than conventional sensors. The high mineral oil and coolant resistance and the immunity against small metal chips on the surface make this sensor ideal for metal cutting or drilling applications.


  • Full body stainless steel housing for highest mechanical protection
  • Low frequency modulation for metal chip immunity
  • Flame retardant cable for high protection against welding spatter damage (pigtail models)

For oil resistant photoelectric sensors in stainless steel housings see the E3ZM-C.
