Omron G6B2114P-FD-US-P6B-DC5 SPST Relay, 5 VDC Coil, Current

The G6B2114P-FD-US-P6B-DC5: SPST form means one normally-open contact set — clean for switching a single load line, pilot duty, or signal-level isolation. The 5 VDC coil is common in logic-level control circuits, so it drops into existing 5 V rail designs without a separate supply. No need to gut the whole control scheme to swap this in.
