Why Choose the EMAS CPDEE Emergency Stop Button Head?
The EMAS CPDEE is a 40 mm emergency stop button head designed for industrial machinery, automation equipment and operator control stations. Part of the EMAS CP Series, it provides a clearly identifiable emergency-stop operator for use with compatible 22 mm industrial control assemblies.
The CPDEE features a 40 mm mushroom-style operating head with a twist-release mechanism. Once actuated, the operator remains in its operated position until deliberately released by rotation, providing maintained operation for emergency-stop control applications.
Designed for 22 mm mounting systems, the CPDEE can be combined with compatible EMAS contact elements to create the required emergency-stop switching arrangement. The operator is also supplied with an emergency-stop legend, providing clear identification when installed on industrial machinery and control panels.

Emergency Stop Operation for Industrial Control Systems
Emergency-stop operators provide a clearly identifiable manual control point for initiating an emergency-stop command within a suitably designed machine safety circuit. The EMAS CPDEE uses a large 40 mm mushroom-style head to provide an accessible operator for industrial machinery and control stations.
The maintained twist-release mechanism keeps the operator actuated after it has been pressed and requires deliberate rotation before returning to its normal position. When combined with suitable EMAS contact elements and correctly integrated into the machine control system, the CPDEE provides a practical operator interface for emergency-stop applications.
