Description
HGSR05-2A04
5V 2-Channel High-Current Mercury Wetted Relay, 2 Form A
The HGSR05-2A04 is a dual-channel (2 Form A) high-power mercury wetted reed relay from SHR’s HGSR series, driven by a 5VDC coil. With 5A-class high-current switching per the 2A platform and mercury wetted contacts for bounce-free operation, it suits high-current test and industrial switching applications.
