With its H-473 safety relays, HENGSTLER provides a solution for all those applications that require high component density. The max. height of 15.7 mm enables them to be used in 22.5 mm module housings, for example. The well-designed layout of the relay pins means there is plenty of space at the rear of the circuit board for SMD components. H-473 safety relays conform to DIN EN 61810-3 standard, Application type A, and IEC EN 61810-1. In addition, these safety relays also meet the requirements for railway signal relays in accordance with UIC 736e.
