Purchase now: Atlantech Drives provides you the Schmersal 101190684 (Model: AZM 170-02ZRK 24VAC/DC), a compact and robust Solenoid Interlock Switch designed to keep safety guards locked until hazardous machine movements have ceased. Unlike simple safety switches, the AZM 170 series physically prevents the door from opening, providing a **holding force of 1,000 N**. This specific model is equipped with screw terminals («K») for easy wiring and operates on a **24 V AC/DC** control voltage.
Technical Specifications and Compact Design
The AZM 170 is favored for its double-insulated thermoplastic enclosure, which is resistant to industrial environments (IP 67). The «02» designation indicates it features **2 Normally Closed (NC)** contacts for the safety circuit. The «R» in the code signifies a **Latching Force of 30 N**, which keeps the door in the closed position even when the solenoid is unlocked, preventing the door from popping open due to vibration or air pressure.

Expert Installation Advice: The Actuator Key
The AZM 170 uses a separate actuator key (e.g., AZ 17/170-B1). Expert Tip: A critical installation error is mounting the switch and actuator rigidly without checking for alignment. If the door sags over time, the actuator will grind against the switch head, eventually breaking the plastic head or the metal key. Always verify the insertion radius. For doors with a small radius, use the flexible actuator (B6) to prevent mechanical stress.
Frequently Asked Questions (FAQs)
Q: Is this «Power to Lock» or «Power to Unlock»?
A: Standard AZM 170 models are typically **Power to Unlock** (Spring to Lock). This ensures the door remains safely locked in the event of a power failure, protecting operators from inertia hazards.
Q: Can I use it in wet areas?
A: Yes, it is rated IP 67. However, avoid high-pressure washdowns directly on the key entry slot, as water could enter the mechanism over time.
