Competence within the world of safety: Safety relays

Having recognized the importance of force-guided relay contacts long ago, Hengstler has gathered years of experience in the development and production of safety relays. Today, we serve a very demanding international clientele who use our safety relays for the most diverse applications and appreciate our extensive technical advice, our professional project management and our wide spectrum of products.

The key features of our safety relays for elevator systems are their high switching power, excellent reliability and small size. The reinforced insulation between the individual contacts and the coil ensures SAFE electrical separation between logic and load contacts to IEC 60664-1.

Applications: elevator control, door control, hydraulic control, increased safety during maintenance. 

Three models from our wide range of safety relays:

H-472/473		H-462/464/466		H-468/469
Only 15.7 mm high, with reinforced insulation		For switching currents up to 10 A and max. 10 contacts per relay		Low coil power and small size
