Description
MH24-1A10K
24V Mercury Wetted Reed Relay 1 Form A
The MH24-1A10K is a mercury wetted reed relay from SHR’s MH series, driven by a 24VDC coil with 1 Form A (SPST-NO) contacts. Mercury wetted contacts deliver bounce-free switching with stable low contact resistance over life, making it suitable for high-reliability switching in industrial automation, test equipment and instrumentation.
