The EX-AZ 3350-12ZUEK-3D is a safety switch equipped with an independent actuator, specifically engineered for deployment in hazardous dust environments classified as Ex-Zone 22.
Designed to monitor movable mechanical guards (such as doors or hatches) and access points. When guards are opened or removed, the switch immediately halts equipment operation or prevents activation, supporting rigorous functional safety protocols. The independent actuator design isolates the switch body from the trigger component for highly flexible integration options.
Compliant with ATEX/IECEx standards for Ex-Zone 22 environments where combustible dust (such as flour, metal powder, or plastic granules) may be present intermittently. The dust-tight enclosure and specialized interior components mitigate ignition risks in challenging zones common to food processing, pharmaceuticals, and metalworking.
Housing Material: Impact-resistant, dust-proof, industrial-grade corrosion-resistant light alloy die-casting for robust durability.
Dimensions & Features: Compact footprint (40.5 x 114 x 38 mm) ideal for tighter environments. Includes a secure locking handle to prevent accidental disengagement, an M20x1.5 cable entry for secure wiring, and an optional positioning device to ensure correct actuator alignment.
Contact Reliability: Built to maintain precise electrical contact under low-voltage and low-current conditions, ensuring critical safety interlocks trigger flawlessly.
Lockout/Tagout (LOTO): Fully compatible with SZ 415 lockout tags, enabling staff to physically lock the switch in the open position during standard maintenance procedures to prevent accidental start-up.
