Emergency Stop Switches / E-Stop Switches Emergency Stop: Flush Mounting 40 mm Push Button; Environ. Rating: IP65; Lighted; Color: Green, Red Solid/Flashing; 2 N.C. Safety Contacts; 1 N.O. aux. Contacts; 8-pin M12 QD
Research Notes
1. What this is
SSA-EB1PLGR-12ED1Q8 is a Banner Engineering SSA emergency-stop button.
2. Part-number decode
- Series: Banner Engineering SSA
- Type: emergency-stop
3. Compatibility & ordering
Banner Engineering makes illuminated E-stop buttons (SSA), indicator/pick-to-light devices (K50/K80), tower lights, and wireless nodes. Match by type, actuation, illumination, sealing, and mounting, then use the manufacturer datasheet to confirm the exact contact and termination encoded in the part number.
4. Data-quality note
The Banner Engineering series and switch type are decoded from the part number (grounded in the manufacturer catalog and distributor listings). The exact contact arrangement, termination, and cap/colour are encoded in the full order code — confirm against the datasheet for a precise order (not guessed here).

Banner SSA-series In-Series Diagnostics emergency-stop pushbutton (illuminated E-stop with per-device diagnostics; NC safety contacts)
|
Installation Quick Reference
Panel cutout: 22mm. Mount with the yellow backing plate visible (required by EN/ISO 13850).
Wiring: Wire NC contacts in series with the safety relay input channels. Use dual-channel wiring for SIL 3 / PLe applications. Never wire directly to a motor contactor.
Testing: Press the e-stop and verify the machine stops within the required time. Test the reset mechanism. Repeat monthly per EN/ISO 13850.

Troubleshooting
E-stop won't reset (twist/pull doesn't release)
Check for debris in the mechanism. For twist-release: turn clockwise 45-90 degrees. For push-pull: pull straight out firmly. If the mechanism is stuck, the internal latch may be damaged — replace the entire head assembly.
Machine doesn't stop when e-stop is pressed
Critical safety issue. Immediately lock out the machine. Check wiring — NC contacts must be in series with the safety relay. Verify the safety relay is functioning. A broken wire in an NC circuit should cause a stop, so check for a wiring bypass.
Safety relay faults after e-stop reset
The safety relay detects a cross-fault between the two monitoring channels. Check that both NC contacts on the e-stop are switching simultaneously. One contact may be welded closed — replace the contact block.
