RKE-LS Sealed Power Relay is the latest design in power relays. It is engineered for harsh working environments where performance and reliability are critical. The RKE-LS excels in oily, dusty, and humid conditions. Its IP62 protection rating ensures dust and water resistance.
Request A QuoteRKE sealed power relays consist of a relay and a socket. Control voltage ranges can be extended by using matched sockets. They can be used with the following types of sockets: SYF08A-E socket, SYF11A-E socket, SYF14A-E socket, SYF08A socket, SYF11A socket, SYF08A socket, SKB08-E socket, SKB14-E socket, and so on.
