The high durability stainless steel sensing face provides 20 times more protection against mechanical damage than conventional sensors. The family has high mineral oil and coolant resistance along with small metal chip immunity which makes this sensor ideal for metal working applications like cutting, drilling, or tapping.

  • 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.
