Omron G7SA5A1B is a 6-pole safety relay with 5 normally-open (5PST-NO) and 2 normally-closed (DPST-NC) contacts, 24 VDC coil, flux-tight sealed. Standard type — no forced-guided contacts, so it fits basic safety circuits where the relay itself is not the sole monitoring element. The flux-tight seal means the housing withstands wave-solder flux ingress during PCB assembly; fine for automated production but not rated for washdown.
Contact Configuration & Fit
Five NO poles handle the safety output channels (e.g., dual-channel monitoring with feedback loop); two NC poles serve as auxiliary status contacts or a second safety path. The 6-pole count is high for a compact safety relay — typical 3- or 4-pole relays would need two units to match this contact density.
