Autonics BJ photoelectric sensors – a compact solution with a wide range of detection modes

The Autonics BJ series are versatile, compact photoelectric sensors designed for reliable detection of objects in various industrial environments. The devices feature long operating range, interference resistance and adjustable sensitivity, allowing for precise adjustment of operating parameters. A wide selection of detection types – from through-beam, reflective and background suppression to transparent glass and micro-detection versions – makes the BJ series suitable for automated production lines, inspection systems and specialised applications.

• Long detection range – up to 15 m (barrier type), 3 m (reflective with polarisation), 1 m (diffuse reflection).

• Compact housing – only 20×32×10.6 mm, ideal for installation in confined spaces.

• IP65/67 protection rating – high resistance to dust and water in accordance with IEC standards.

• Light ON / Dark ON mode – switchable via a VR potentiometer, flexible adaptation to the application.

• Integrated sensitivity adjustment – precise calibration of the detection level.

• MSR (Mirror Surface Rejection) function – eliminates false signals from mirrored surfaces (polarised reflective models).

• Detection of transparent materials – stable detection of glass, film, LCD screens (e.g. model BJG30-DDT).

• Micro-detection – identification of very small objects, e.g. Ø0.2 mm wire (BJN series).

• Advanced safety features – protection against reverse polarisation, short circuit and overload.

• BGS background suppression – minimisation of the influence of colour, material and surroundings (BGS reflective type).
