Purchase now: Schmersal AZ16ZVR-1876 Safety Interlock
Purchase now: Atlantech Drives provides you the Schmersal AZ16ZVR-1876, a specialized variant of the legendary AZ 16 series Safety Switch with Separate Actuator. This model is distinguished by its integrated Latching Force (30 N), indicated by the «R» in the type code. It is designed for safety guards and gates that are subject to vibration or airflow that might cause a standard door to rattle or drift open, causing nuisance machine stoppages.
Technical Specifications and Robust Design
The AZ16ZVR-1876 features a glass-fiber reinforced thermoplastic enclosure that is self-extinguishing and resistant to industrial contaminants. The «ZVR» designation typically implies a contact configuration (often 2 NC or 1 NO / 2 NC depending on the exact sub-version) with a snap-action mechanism that prevents contact chatter. The **30N retention force** ensures the door stays physically closed without needing a separate magnetic catch, simplifying the mechanical design of your machine guarding.

Expert Installation Advice: Preventing Actuator Breakage
The most common failure mode for the AZ 16 series is broken actuators due to door sag. Expert Tip: When installing the AZ16ZVR-1876, ensure the actuator enters the head smoothly without lifting or forcing the switch. Because this model has a 30N latching force, you will feel resistance when closing; this is normal. However, do not confuse this latching resistance with misalignment friction. Use the slotted mounting holes to align the switch perfectly with the door radius to ensure long service life.
Frequently Asked Questions (FAQs)
Q: What does the «1876» suffix mean?
A: Numerical suffixes in Schmersal codes often refer to customized versions, such as specific contact materials (gold-plated) or pre-mounted glands. It functions identically to the standard AZ 16 ZVR regarding safety logic.
Q: Is the actuator included?
A: No, the switch body and the actuating key (e.g., AZ 15/16-B1) are sold separately to allow you to choose the correct radius (straight, angled, or flexible).
