Pilot Light 120V AC Blue LED
This SIEMENS pilot light provides a blue LED indication at 120V AC for industrial control panels and machinery. The round 22 mm unit suits operators who need clear visual status feedback in automated systems. Its IP67 and IP69K ratings allow use in wet, high-pressure washdown environments. The integrated lamp module removes the need for separate bulb replacement.
Upgrade from basic indicator lights
The sealed construction replaces non-rated pilot lights that fail when exposed to moisture, coolant spray or aggressive cleaning cycles. NEMA 1, 2, 3, 3R, 4 and 4X ratings cover indoor and outdoor enclosures where dust and water ingress are concerns. The jump is worth it when downtime from a failed indicator halts a production line or masks a safety condition. Buyers who only need a simple dry-location status light will not benefit from the added sealing.
Screw-terminal installation notes
The screw-terminal connection accepts standard wire ferrules or stripped conductors for a secure fit in vibration-prone cabinets. A 22 mm panel cut-out is required; verify the mounting hole before drilling. The zinc-alloy body and plastic lens resist impact but can be damaged by over-torquing the locking nut. Ensure the supplied gasket seats evenly to maintain the IP69K seal during high-temperature washdown.

Questions about this item
What size panel cut-out does the 22 mm round body require?
The round pilot light fits a standard 22 mm panel cut-out and mounts with its integral screw terminals.
How is the 120V AC LED module wired during installation?
Connect the supply wires directly to the screw terminals; the LED module is integrated so no separate lamp holder is needed.
When should the sealed blue lens assembly be replaced?
Replace the complete unit if the LED output fades or the IP67 and IP69K seals show damage, as the lamp is not user-replaceable.
