To ensure that our relays as used in your applications carry on doing their job reliably for years, the quality of products bearing the HENGSTLER name is the highest priority. All our locations are certified to ISO 9001 and ISO 14001, and the entire product range is, as you would expect, in conformity with RoHS and REACH regulations.

For decades, HENGSTLER has been intensively involved in matters relating to forcibly guided, or captive, contacts and, as a result, with safety relays. Our large, international customer base benefits from this experienced gathered over many years when it comes to developing and manufacturing relays with forcibly guided contacts. HENGSTLER's H-463 safety relay is used wherever a high number of switching actions is required at moderate switching loads. H-463 safety relays conform to EN 50205 standard, Application type A, and IEC EN 61810-1.
