DLF1/7 or DL1/6
for single-leaf doors
The basic device for single-leaf doors covers the most common applications. The integrated contact holder insert with contact for locking mechanism and optional auxiliary switches enables a clean and safe wiring. The device can be supplemented by an adjustable door switch for monitoring the closed position.

Features
general:
- metal housing with high stability
- transparent cover for optimal function control
- silent due to buffers in both dircections
- maintenance-free by permanent lubrication with high quality lubricants (up to -30 °C)
- oiled felt ring at latch bolt for lubrication as well as for sealing against dirt and dust (at X-dimension ≥ 10 mm)
- constrained faulty closure at DLF1/7 for use in passenger lifts
- contacts with solid fine silver plating for a reliable function even at low voltages and currents
- auxiliary switch as normally closed contact and/or normally open contact with two galvanically isolated
contacts possible - extensive range of accessories
special features:
- contact holder insert with switch for locking mechanism and double auxiliary switch as option
- optional: adjustable door switch for monitoring the closing position (PZ73)
- comfortable wiring by large terminal compartment
- terminals with pressure plate for the connection of two lines
- 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)
