D4N
This basic safety limit switch can have different actuators
(for example roller lever and roller plunger) to suit the
application. Designed for door monitoring, it is the ideal
additional safety measure in case the main safety switch fails.
In addition to machine directive related standards the D4N
conforms to EN115 (for escalators) and EN81 (for lifts).
D4NR
This manual reset switch works like an ordinary limit switch,
but once it’s activated, the system that it protects remains
in the OFF position until the switch is manually reset. Of course

The D4NS offers superior features at a very attractive price,
in a size that is in accordance with EN 50047.

critical applications to provide mechanical redundancy
in systems up to Category 4.
