Why Choose the ABB 1SFA611103R2001 MP4-20R Pushbutton?

The ABB 1SFA611103R2001, also known as the MP4-20R, is a durable maintained extended pushbutton operator designed for industrial machinery, automation systems and electrical control panels. As part of the versatile ABB Modular pilot device range, it provides reliable manual control for applications where the selected command must remain active after the operator releases the pushbutton.

The MP4-20R features a red, non-illuminated extended actuator with a chrome-coloured plastic bezel. Its maintained, or latching, operating action provides a stable selected position rather than automatically returning after release. This makes the operator suitable for machine and process functions that require a retained command, while ABB's modular construction allows the required contact blocks and accessories to be configured separately.

Designed for standard 22 mm panel mounting, the 1SFA611103R2001 provides IP66 front protection together with a NEMA 4X front rating. Mechanical durability of approximately 2 million operations and compact 29 × 29 × 39 mm dimensions make it a dependable choice for operator stations, control cabinets and industrial machine interfaces.

Reliable Maintained Control for Industrial Machinery

Maintained industrial pushbuttons provide operators with a dependable method of controlling machinery and automated processes where a command needs to remain selected after operation. Unlike a spring-return pushbutton, the ABB MP4-20R retains its operating state after the actuator is released, making it suitable for applications requiring a persistent manual command.

ABB's modular pilot device system allows operators, contact blocks and accessories to be combined according to the requirements of the control circuit. The MP4-20R's extended actuator, standard 22 mm mounting format and high front protection ratings make it suitable for machine-mounted operator panels, enclosed control stations and industrial automation equipment.

Typical Applications

• Industrial machinery control panels.
• Factory automation and production equipment.
• Motor and process control systems.
• Operator control stations and consoles.
• Manufacturing and material handling equipment.
• Retained machine function selection.
• OEM machine building and electrical control cabinets.
