Why Choose the ABB MPEK4-12R Emergency Stop?
The ABB MPEK4-12R is a robust 40 mm key-release emergency stop pushbutton operator designed for industrial machinery, control panels and automation systems requiring a secure and clearly identifiable emergency stopping control. Supplied under ABB order code 1SFA611525R1201, it forms part of ABB's modular plastic pilot device range and provides dependable operation in safety-related machine control applications.
The MPEK4-12R features a red 40 mm mushroom actuator with maintained latching operation and a key-release mechanism using key code 421. Once pressed, the emergency stop remains mechanically latched until deliberately released using the appropriate key, providing controlled resetting of the operator.
Designed for standard 22 mm pilot-device mounting, the MPEK4-12R is a non-illuminated operator supplied without a contact block. Its IP66 and NEMA 4X protection ratings, modular construction and durable industrial design make it suitable for machinery, production equipment and automation installations requiring a key-reset emergency stop.
Key Advantages

Controlled Emergency Stop Reset for Industrial Machinery
Key-release emergency stop operators combine a prominent manual emergency control with a controlled reset method. After the mushroom actuator is pressed, its maintained mechanism keeps the operator latched until the correct key is used, helping ensure that resetting is a deliberate action rather than an accidental movement of the actuator.
The ABB MPEK4-12R combines a 40 mm red mushroom actuator with key code 421 and ABB's modular pilot device architecture. Compatible ABB holders and appropriate contact blocks can be selected separately according to the requirements of the emergency-stop circuit, allowing the operator to be incorporated into machinery and industrial automation systems.
Typical Applications
- Industrial machinery emergency stop controls.
- Production and manufacturing equipment.
- Conveyor and material handling systems.
- Packaging and processing machinery.
- Automation and machine control panels.
- Operator stations requiring controlled emergency-stop reset.
- OEM machinery and safety-related control assemblies.
