Autonics Universal AC/DC Photoelectric Sensor - BEN5M-MDT

Relay, Cable type connection, Sensitivity adjuster


The Autonics photoelectric sensor BEN5M-MDT with built-in IC photo diode can sense objects without the ambient light and electrical noise affecting the process. This sensor which is Retroreflective type, comes in a rectangular shape, sensing distance of 5m, Sensing target of min Ø60mm and Rectangular installation. The standard rectangular photo sensor can be used in diverse applications requiring non-contact detection of Opaque material.

As a quick report, this photoelectric sensor provides:

  • 5m sensing distance
  • Relay control output
  • ≥ Ø 60 mm min. sensing target
  • Infrared LED (940nm) Light source
  • Small and power supply built-in type.
  • Easy installation with indicators on product.
  • Light ON/Dark ON mode selectable by switch.
  • IP50 ingress protection structure according to IEC standards
  • Status and output indication.
  • Built-in IC photo diode for disturbing light and electrical noise.
  • ≤ 20 ms Response time
  • Operation indicator (red), stability indicator (green), power indicator (red)


This Autonics photoelectric sensor's case and case cover are made of Heat resistant Acrylonitrile butadiene styrene, its sensing part is made of Polycarbonate (with polarizing filter: polymethyl methacrylate).

The BEN5M-MDT features IP50 ingress protection.

The green and red LED on its body acts as the process indicator.


The Autonics sensor BEN5M-MDT features standard cable type connection. This cable is 5 mm in diameter and 2 meters in length.

Sensing specifications
