Product Description

Background suppression:
·         Very precise, sharp object identification
·         Detection irrespective of background, shape and surface finish of the objects
·         External Teach and g Teach
·         Baumer PinPoint LED

1. Comfortable and fast teaching procedure with ferromagnetic tool (q Teach); secure and wear free.
2. Comfortable thanks to display LEDs visible from all sides.
3.  Maximum flexibility thanks to uniform housing design for two technologies (ultrasonic and optoelectronic).
4.  Sealed housing for absolute impermeability.
5.  Exact positioning and detection of small parts thanks to Baumer PinPoint LED
