Ismertetés

Switching elements

ES 502 E	Snap-action switching contact 1 NC + 1 NO
ES 508	Slow-action switching contact 1 NC

On the usage of safety switching elements, the dog distance must be maintained to achieve the positively driven travel. The dogs must be positively mounted according to EN ISO 14119, i.e. riveted, welded or secured in some other way against becoming loose.

Dimensional drawings

*	Safety switching element ES 508E positively driven. Positive opening function is dependent on maintaining this distance.
