Photoelectric sensors use a beam of light to detect the presence or absence of an object. This technology is used to identify the size and contrast of an object. 4 kinds of general-purpose photoelectric sensor product lines are designed to ensure advanced technology performance combined with optic & electric technology and are widely applied in various fields of industry for its optimized functions, quality, application flexibility, and reliability while remaining strongly competitive with its price among the whole industry. Application areas of photoelectric sensors include industrial automation lines, elevators, parking facilities, logistics services, semiconductor devices, packaging machines, and construction areas.

The BR series Ø18 mm cylindrical photoelectric sensors feature long detection distance up to 20 m (through-beam-type) and high-speed response time under 1ms. The series also features excellent noise immunity with digital signal processing. The BR series is available in 4 different sensing modes, making it practical for a wide variety of applications. Connector type sensors are also available, offering easier maintenance and wiring work.

BR3M-MDT-P from Autonics is a Photoelectric Sensor with polarity PNP (control output). The sensing type is retro-reflective, with light and dark ON operation mode, round shape type and with a sensing distance of 3m.

BR3M-MDT-P from Autonics comes with the following properties:

  • External sensitivity adjustment (diffuse reflective type).
  • IP66 rated waterproof structure (IEC standard).
  • Detects up to 20m (transmitted beam-type).
  • Noise resistant with digital signal processing.
  • Narrow beam-type diffuse reflective sensor using in a narrow space.
  • Reverse power polarity and short-circuit (over-current) protection circuit.
  • High environmental resistance BR4M series with mirror lens.
