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.
