Features:

general:

metal housing with high stability
transparent cover for optimal function control
silent due to buffers in both directions
maintenance-free by permanent lubrication with high quality lubricants (up to -30 °C)
oiled felt rings at the latch bolts for lubrication as well as for sealing against dust and dirt (at X-dimension ≥ 10 mm)
constrained faulty closure at DLF2 for use in passenger lifts
auxiliary switch as normally closed contact and/or normally open contact with two galvanically isolated
contacts possible
contacts with solid fine silver plating for a reliable function also at low voltages and currents
extensive range of accessories

special features:

two latch bolts for double-leaf doors
terminal block with all electrical connections
optional: separate door switches for monitoring the closing position of both door leafs
reduced wiring due to internal series connection of the contacts for locking mechanism and the optional door switches
connection for bowden cable or cable pull for actuation or unlocking available, e.g.
application 1: unlocking from the pit ladder (< 1.80 m according to EN 81-20)
application 2: offset emergency release triangle (< 2 m according to EN 81-20)
