EL(F)1
for single-leaf doors
This door interlock is the compact version of the DL(F)1. The device meets the essential quality features of the larger design, however with reduced type diversity. The EL(F)1 is often used for the modernization of lift installations, if no longer available door interlocks of other competitors have to be replaced.

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 ring at latch bolt for lubrication as well as for sealing against dirt and dust (at X-dimension ≥ 10 mm)
- constrained faulty closure at ELF1 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 galvanically separated
contacts possible - extensive range of accessories
special features:
- technology of the DL(F)1 in compact design
- contact holder insert with switch for locking mechanism and optional double auxiliary switch
- screw terminal with pressure plate for both-sided line connection
- options for door switches for monitoring the closing position:
– internal door switch (not adjustable)
– external adjustable door switch (PZ73) - connection for bowden cable or cable pull for actuation of unlocking available, e.g.
