S41 Miniature

Key Features

  • Diffuse or fixed focus proximity for background suppression
  • Polarized retro-reflective and emitter-receiver with narrow beam
  • Models with trimmer setting
  • Double NO-NC NPN or PNP output


The S41 series offers a basic line of photoelectric sensors in miniature housing, ideal for applications that require reduced dimensions and costs. The optic functions include a diffuse proximity adjustable from 0 to 35 cm and a 11 cm fixed focus proximity suitable for background suppression; 2.5 m polarized retro-reflective, 1 m retro-reflective for transparent and 6 m through beam are available for longer operating distances; the latter is also available in a narrow beam emitter version that allows to place sensors side by side without interferences.

The LED emission is red for the fixed focus proximity and infrared for the other models. Two LED indicators are visible on the sensors: a yellow output LED and a green switching stability LED; the diffuse proximity models and a polarized retro-reflective version also present a sensitivity adjustment trimmer. The normally open and normally closed outputs are both present on different poles; cable or M8 connection is offered according to the model chosen.
