Why Choose the ABB MPEK4-13R Emergency Stop?
The ABB MPEK4-13R is a robust 40 mm key-release emergency stop operator designed for industrial machinery, control panels and automation systems requiring a secure and clearly identifiable emergency stopping control. Supplied under ABB order code 1SFA611525R1301, it forms part of ABB's modular plastic pilot device range and provides a durable operator interface for safety-related machine control applications.
The MPEK4-13R features a red 40 mm mushroom actuator with a maintained latching function and key-release mechanism using key code 3433-E. Once pressed, the emergency stop remains mechanically latched until the appropriate key is turned to release it, providing a controlled reset method and helping prevent unintended resetting of the operator.
Designed for the standard 22 mm pilot-device format with a 22.5 mm mounting hole, the MPEK4-13R is non-illuminated and supplied without a contact block. Its IP66 protection, operating temperature range of -25 to +70 °C and modular ABB construction make it suitable for demanding machinery, manufacturing and industrial automation environments.

Controlled Emergency Stop Reset for Industrial Machinery
Key-release emergency stop operators combine a prominent manual emergency control with a controlled reset procedure. After activation, the mushroom actuator remains latched and the appropriate key must be used to return the operator to its normal position, making the reset a deliberate action rather than an accidental movement of the actuator.
The ABB MPEK4-13R combines a 40 mm red mushroom actuator with key code 3433-E and ABB's modular pilot device architecture. Compatible ABB holders and suitable contact blocks can be selected separately according to the requirements of the emergency-stop circuit, allowing the operator to be incorporated into appropriately designed machinery and industrial automation safety systems.
Typical Applications

- Production and manufacturing equipment.
- Conveyor and material handling systems.
- Packaging and processing machinery.
- Automation and machine control panels.
