The new PRK 46B retro-reflective opto-electronic sensor from Leuze Mayser can be built into materials handling applications more quickly and efficiently, thanks to a simple and secure push-pull connection system called Ultralock. Aiding installation further, the device also offers brightVision technology, featuring top-mounted bright LEDs and a significantly more visible light spot for easier alignment of sensor and reflector. Sensing distance ranges from 18m down to just 5cm and the PRK 46B's protection class is IP69.
