30 mm Red Mushroom Head for Emergency Stop

This Schneider Electric 9001K93R is a 30 mm red mushroom head designed for industrial emergency-stop and safety-control panels. It mounts on compatible 9001KR25 or 9001SKR25 operators and provides a non-illuminated, plastic actuator for manual machine shutdown.

Environmental ratings limit where it can be used

The head carries NEMA 1, 12, 3R, 4 and 4X ratings plus IP66, so it resists dust, water jets and corrosion in indoor or outdoor enclosures. It is not rated for submersion, hazardous-location atmospheres or extreme temperature cycling beyond the base operator specification.

Screw-on mounting with included set screw

Installation threads the head onto the operator and secures it with the supplied set screw using basic hand tools. Misalignment during threading or an overtightened set screw can damage the plastic threads, while omitting the set screw risks the head loosening under vibration.

What does the NEMA 4X and IP66 rating mean once the head is installed?

The screw-on connection secures the plastic head to compatible 9001 series operators using the included set screw for a firm mechanical fit.
