- noticeActuating distance up to 60 mm depending on actuating magnet and version

The specifications with regard to the switching distances apply to the actuation of the individually mounted devices without ferromagnetic influence. Any change of the
distance, positive either negative, is possible due to ferromagnetic interference. When multiple actuating magnets are used, the mutual
interference must be observed.

The opening and closing functions depend on the direction of actuation, the actuating magnets and the polarity of the actuating magnets.
When the switches and actuators come together, the colours must coincide: Red (S) to red (S) and green (N) to green (N).
This does not apply to the bistable contact.
Included in delivery
Actuators must be ordered separately.
