It's rated IP67, so the seal holds up in washdown zones or damp panel interiors. The M25 thread matches standard knockouts on plastic or metal AS-i boxes with 4 to 6 control points. Fastening is direct mounting — no DIN rail, no adapter plate. You drill or punch the enclosure, tighten the locknut, and run the cable through. ## Integration note This is a gland, not a contactor or sensor — it has no electrical ratings beyond the IP seal and temperature range. The M25 thread accepts a round cable of appropriate diameter; the enclosure side must have a matching knockout. For an AS-i box with 4 to 6 control points, this is the factory-specified entry part.","metaTitle":"3SF5900-0CK Connection Element, M25, IP67, -25 to +70 °C","metaDescription":"3SF5900-0CK connection element for routing round cable into AS-i enclosure.
