Purchase now: Schmersal 101167190 AZ 16 Safety Interlock
Purchase now: Atlantech Drives provides you the Schmersal 101167190 (Model: AZ 16-02ZVRK), a variant of the globally recognized AZ 16 series Safety Interlock Switch. This specific configuration is designed for applications prioritizing redundancy, featuring 2 Normally Closed (NC) contacts without a signaling NO contact. This makes it a dedicated component for dual-channel safety circuits where maximum reliability in stopping hazardous movement is required upon guard opening.
Robust Design and Latching Force
The 101167190 is built to last in harsh industrial environments. It features a glass-fiber reinforced thermoplastic housing that is self-extinguishing and resistant to industrial oils and chemicals. The «R» in the model code indicates a Latching Force of 30N. This mechanical retention holds the safety guard (door/gate) in the closed position effectively against machine vibration, preventing «nuisance tripping» where the machine stops unexpectedly due to a loose door, thereby increasing production uptime.

Expert Maintenance Tips: Checking for Cam Wear
The AZ 16 mechanism relies on a mechanical cam and actuator key. Expert Tip: In high-cycle applications (e.g., a door opening every minute), inspect the entry throat of the switch annually. If you see excessive white plastic dust or metal shavings, it indicates the door is misaligned and the actuator is grinding against the switch head. Re-align the door immediately. Continued operation with misalignment will eventually break the actuator key or the switch head, bypassing the safety function.
Frequently Asked Questions (FAQs)
Q: Can I upgrade a 1 NC switch to this 2 NC model?
A: Yes, they share the same physical footprint. Using 2 NC contacts allows you to upgrade the safety circuit from Category 1 to Category 3 or 4 (Dual Channel) for higher safety PLr requirements.
Q: Is the actuator included?
A: Generally, actuators (straight, angled, or flexible) are ordered separately to match the specific radius of your door.
