ABB MP2 Series Green Maintained Push Button Head, 22.5 mm Cutout, IP66

ABB MP2 Series Push Button Head, 22.5mm Cutout Diameter, Green - 1SFA611101R2102

This push button head provides a user-operable Interface for industrial control panels, enabling maintained actuation in harsh environments. It is designed for panel mounting with a standard 22.5mm cut-out and offers a high degree of protection against ingress, making it suitable for outdoor and washdown conditions. The actuator presents a green, round appearance and is constructed from chrome-finish plastic for Visual clarity and corrosion resistance in routine industrial use.

Features and Benefits:

• Maintained operation ensures stable on/off control 22.5mm cut-out compatibility simplifies panel integration IP66 protection prevents dust ingress and powerful water jets Chrome plastic construction reduces corrosion risk and weight Unmarked green actuator offers clear operator signalling Conforms to multiple international standards for consistent performance

Applications

• Suitable for control stations in factory automation systems Ideal for motor starter and machine stop/start panels Used with electrical enclosures requiring robust sealing Can be used for operator interfaces on assembly-line machinery Suitable for retrofit upgrades in industrial control cabinets

What mounting hole size is required for installation?

It requires a 22.5mm panel cut-out to secure the head in place.

How does the actuator behave when operated by an operator?

The switch remains in the selected state after actuation due to its maintained mechanism.

What environmental resistance does it offer against water and dust?

The enclosure rating is IP66, which blocks dust and withstands powerful water jets.

What material is the actuator formed from and why is that relevant?

The head is moulded from chrome-finish plastic, offering a corrosion-resistant surface while keeping mass low.

Which standards govern its electrical and mechanical design?

It meets a range of international standards covering switchgear and enclosure performance to ensure interoperability and safety compliance.
