Frequently Asked Questions

What safety rating does this switch provide?

When used in properly designed safety circuit, achieves Category 3, PL d per ISO 13849-1. Direct opening action ensures safety even if contacts weld.

What's direct opening action?

NC contacts opened by direct mechanical force from actuator, not by spring. Even if contacts weld, actuator physically forces them open. Required for safety applications.

What applications use D4B series?

Machine guard interlocks, safety gate monitoring, emergency stop circuits. Any application requiring certified safety interlock.

Can this switch be used outdoors?

Yes, IP67 rating and metal enclosure suit outdoor use. Protect conduit entries from moisture.
