Machine-Guard Safety Screw Terminal Relays
The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding. The screw terminals are recessed to prevent accidental contact with live connections. Relays are built to International Electrotechnical Commission (IEC) dimensional standards.
Auxiliary contact (sold separately) allows you to add a signaling device or control another relay.
