Features and Benefits:

• Key release actuation prevents accidental reset and unauthorised restart
• Plastic mushroom actuator improves grip and Rapid manual handling
• Red colour enhances Visual identification in safety circuits
• Compatible with 22.5mm panel cutouts for standard mounting
• Dual IP ratings provide sealed external protection and internal enclosure flexibility

Applications

• Suitable for emergency shutdowns on factory automation panels
• Ideal for installation on control stations in electrical distribution boards
• Used with machine guards in mechanical fabrication environments
• Can be used for safety interfaces in electronics assembly lines

What mounting aperture is required for installation?

It fits a 22.5mm panel cutout, allowing retrofit into common control enclosures.

How does the actuator behave in dusty or wet environments?

The head carries IP66 protection externally for dust‑tight and powerful water jets, while IP20 applies to internal enclosure conditions.

Is the actuator illuminated for low‑light situations?

No illumination is provided

the design relies on its red colour and mushroom form for visibility.

What release method is used to reset the actuator after operation?

A key‑operated release mechanism is required to reset the actuator and permit restart.
