Siemens 3SU1900‑0FX20‑0AA0 SIRIUS ACT Red ID Key (ID Group 3) Original Brand New

Overview

The Siemens 3SU1900-0FX20-0AA0 is a crucial accessory for the SIRIUS ACT 22mm command and signaling device series. This component is a plastic ID key designed for use with compatible ID key-operated switches, providing controlled access and operation within industrial automation and control systems. It features RFID coding set to ID Group 3 and is easily identifiable by its red color. The key is built for durability and reliable performance in demanding industrial environments, ensuring secure operation of key-operated switching functions.

Benefits

• Enhanced Security: Provides coded, restricted access control for critical machine functions using ID key-operated switches.

• System Integration: Fully compatible and designed specifically for the Siemens SIRIUS ACT 22mm modular system.

• Robust Construction: Made from durable plastic, ensuring long-term reliability and high media resistance (e.g., to oils, vapors).

• Easy Identification: Red color and ID Group 3 coding allow for clear operational segregation and management.

• Industrial Durability: Part of the SIRIUS ACT range known for high protection ratings (e.g., up to IP69(k)), suitable for harsh environments.

Function

This ID key acts as the physical key for a key-operated switch actuator within a control panel. When inserted into the corresponding SIRIUS ACT ID key-operated switch (e.g., a 3SU1 series switch), it completes the circuit, allowing the operator to engage or disengage a function (such as starting a machine, switching modes, or enabling safety functions). The integrated RFID coding (ID Group 3) ensures that only this specific key group can operate the designated switch, adding a layer of security and access control beyond a simple mechanical key.
