ABB MPEK4-11B is a non-illuminated 40 mm black mushroom machine stop operator with maintained operation, code 455 key release and IP66 protection for industrial machinery and control panels.
£30.21
The ABB MPEK4-11B is a robust key-release machine stop operator designed for industrial machinery, control panels and automation equipment. Part of ABB's Modular plastic pilot device range, it combines a large black mushroom actuator with a key-operated release mechanism for applications where controlled resetting of a machine-stop command is required.
The MPEK4-11B features a 40 mm black mushroom actuator and uses key code 455 for release. The operator has two stable positions and remains latched after actuation until deliberately reset by turning the key, helping prevent casual or unintended resetting of the machine-stop control.
Designed for standard 22 mm pilot-device mounting, the MPEK4-11B is non-illuminated and supplied without contact blocks, allowing compatible ABB modular contact elements to be selected separately for the required control circuit. It provides IP66 and NEMA Type 4X protection for demanding industrial installations. ABB identifies this exact machine stop under order code 1SFA611525R1106.
Machine stop operators provide a prominent manual control for stopping industrial equipment. The ABB MPEK4-11B uses a 40 mm black mushroom actuator with maintained operation, so the operator remains in its actuated state after being pressed rather than automatically returning to its normal position.
Resetting is performed by turning the appropriate code 455 key, providing greater control over who can restore the operator after a stop command. ABB's modular construction allows suitable holders and contact blocks to be selected separately, enabling machine builders and panel manufacturers to configure the electrical switching arrangement required by the application.
