1SFA192012R9001 ABB P9MEC4RN37 Red 40 mm Key-Release Mushroom Pushbutton

Why Choose the ABB P9MEC4RN37 Key-Release Mushroom Pushbutton?

The ABB P9MEC4RN37 is a robust red key-release mushroom pushbutton from the ABB P9M modular metal pilot-device range. Designed for demanding industrial control applications, it combines a prominent 40 mm mushroom actuator with maintained operation and a key-controlled release mechanism.

The P9MEC4RN37 uses key code 37 and a maintained switching action, meaning the mushroom actuator remains in its operated position until deliberately released with the appropriate key. This provides controlled resetting where access to the release function needs to be restricted.

Its non-illuminated red actuator, modular metal construction and IP66 front protection make the P9MEC4RN37 suitable for industrial machinery, mining, construction and heavy-industry equipment. It is designed for ABB's 22 mm pilot-device system and can be combined with compatible P9M modular components to create the required control arrangement.

Key Advantages

• Prominent 40 mm red mushroom actuator for clear manual operation.
• Maintained action with key release provides controlled resetting.
• Key code 37 configuration for the specified key-operated release system.
• IP66 front protection supports use in demanding industrial environments.
• Non-illuminated design for straightforward control applications.
• Part of ABB's robust modular metal range for mining, construction and heavy industry.

Controlled Reset for Demanding Industrial Controls

Maintained mushroom pushbuttons remain mechanically operated after actuation until a deliberate reset action is performed. The ABB P9MEC4RN37 adds a key-controlled release mechanism to this functionality, helping ensure that resetting is carried out only by personnel with access to the corresponding key.

The P9M modular metal range is engineered for demanding industrial applications and provides a flexible architecture for combining operators with compatible holders and contact blocks. The P9MEC4RN37 therefore provides a durable front operator that can form part of an application-specific industrial control assembly.
