DL(F)2
with extended range of applications
Basic device for double-swing doors, where both latch bolts are in one housing. Also this model is characterized by many combination options. Door interlocks of DL(F)2 type are installed in the door post above the door.
Door interlock DLF2-L-X15(u).10
Door interlock DLF2-L-X15(u).10
Dimensions DLF2-R-X20(u).10
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)
application 3: actuation by bowden cable as alternative to pull rod - compatible with no longer available KRONENBERG door interlocks (TV2, TVL2)
