Autonics Side Sensing Photoelectric Sensor - BMS2M-MDT-P

Retroreflective, Cable type connection, Sensitivity adjuster


The Autonics photoelectric sensor BMS2M-MDT-P with built-in reverse polarity protection circuit. This sensor which is Retroreflective type, comes in a rectangular shape, sensing distance of 2m, 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:

  • 2m (MS-2) sensing distance
  • PNP Open collector
  • ≥ Ø 60 mm min. sensing target
  • Infrared LED (940nm) Light source
  • Light ON mode - Dark ON mode selectable (control wire)
  • ≤ 1 ms Response time
  • Operation indicator (red)


This Autonics photoelectric sensor's case is made of Acrylonitrile butadiene styrene, its sensing part is made of Acryl.

The BMS2M-MDT-P features Reverse power protection circuit, output short overcurrent protection circuit

The red on its body acts as the operation indicator.


The Autonics sensor BMS2M-MDT-P features standard cable type connection. This cable is 5 mm in diameter and 2 meters in length and covers the sensor's 4-wires.

Sensing specifications
