Mini relay, micro relay and high performance relay
Mini, micro, and high-performance relays offer high reliability for precise switching tasks in vehicles and industrial applications. As electromechanical switches, they completely separate the control and load circuits, thus ensuring safe switching processes in modern E/E systems.
Their compact design, standardized flat plug connections, and variants for 12 V and 24 V vehicle electrical systems enable easy integration into different platforms and applications. The robust construction and high switching capacity make these relays particularly durable and resistant – ideal for demanding applications.
Thanks to their high electrical load capacity and insulation resistances of over 100 MΩ, they also work reliably in sensitive control circuits. The electromagnetic switching technology is designed for high thermal and mechanical stresses and thus meets the requirements of modern vehicle electrical systems. Response and fall times of less than 10 ms enable defined, fast switching – an advantage wherever short response times are crucial.
