Autonics photoelectric sensor 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 BJ series compact photoelectric sensors feature high performance and excellent noise immunity for accurate and reliable presence detection. Light ON/Dark ON operation mode switch and sensitivity adjusters are available for easy configuration and set up (except BJG-DDT). The sensors are available in various types and options, making it ideal for diverse applications. The BJ series is available in long-distance type, BGS (background suppression) reflective type, transparent glass sensing type, and micro spot types, and the sensors are available in cable types and connector types (long-distance type models).

BJ15M-TDT-P from Autonics is a Photoelectric Sensor with polarity PNP (control output). The sensing type is through-beam, with dark ON/light ON operation mode, small long-distance type with a sensing distance of 15m.

BJ15M-TDT-P from Autonics comes with the following properties:

  • Long sensing distance with high quality lens.
  • Waterproof structure IP65 by rubber injection (IEC standard).
  • Compact size.
  • Detects up to 15m (Transmitted beam-type).
  • Long sensing distance: diffuse reflective type 1m, polarized reflection type 3m (MS-3S).
  • Light ON/dark ON selectable.
  • Built-in sensitivity adjuster.
  • Mutual interference prevention function.
    (Retro-reflective type. Diffuse reflective type)
  • Stable detection for the transparent object (LCD, PDP, glass, etc).
