WPS2/B is a non-contact trap protection system for power-operated, automatically operated windows or louvres. Unless requirements apply based on the Machinery Directive, a corresponding system may be used as a universal solution using sensor types with object
recognition by passive infrared sensors and different monitoring areas. If a hazard is identified, windows will stop closing and open.

Unit characteristics
- satisfies the highest protection class requirements
for power-operated windows based on risk assessment
- main and secondary closing edges are monitored as
well as the drive
- independent of drive and controller manufacturer
- extensive monitoring area, individually adjustable
- includes Service Port interface for parameterisation
of a wide range of setting options
- option to connect a motor circuit with an 8 A load
- enhanced safety guaranteed by the option to connect
additional switching strips
- option to connect multiple sensors
- object recognition via temperature differences and a
minimum speed (passive infrared sensor: WPS sensor or
- large or small monitoring area using movement
detection by passive infrared portion (passive infrared
sensor: WPS sensor or "Fly")
