Description

3SU1050-1AD20-0AA0 Overview

The Siemens 3SU1050-1AD20-0AA0 is a robust, industrial-grade 22 mm diameter mushroom pushbutton designed for control panels, machinery, and automation systems. Its round, shiny-metal red actuator (Ø 30 mm) provides excellent visibility and accessibility — especially useful for emergency stop or other critical control functions. The pushbutton operates on a momentary contact type mechanism, making it suitable for applications that require immediate, short-duration control signals.

Function and Application

This pushbutton acts as a human-machine interface (HMI) component, typically used for immediate, non-latching operations. Its momentary function means the circuit is only closed/opened while the operator is actively pressing the button.

  • Common Functions: Start/Stop controls (when used with appropriate contact blocks), Jogging movements, Reset functions, or any application requiring a quick, temporary signal input.

  • Typical Environments: Control panels, machine operating consoles, distribution boards, and emergency/maintenance stations where a large, easily actuated button is necessary.

Benefit

  • High Durability: The metal construction and high-grade materials ensure a long service life, reducing replacement and maintenance costs.

  • Enhanced Visibility: The 30 mm red mushroom head provides excellent visual confirmation and is easy for operators to locate and actuate quickly, a critical feature for process safety and efficiency.

  • Ease of Installation: Complies with the standard 22 mm mounting diameter, allowing for seamless integration into existing control panel cutouts.

  • Reliable Performance: Part of the trusted Siemens SIRIUS ACT range, guaranteeing consistent and reliable signaling for critical control tasks.
