Kaco Safety Relays

Kaco Electrotechnik was purchased by Hengstler in 1996 and now all Kaco relays are manufactured at the Hengstler plant. Kaco has some of the smallest Force Guided relays available.

Their RBS series is the smallest with only 2 contact sets per relay. We have selected some of the more commonly used Kaco relays for our PDF files.
