Purchase now: Atlantech Drives provides you the Schmersal AZ16-12ZVRK-M20, the M20-thread version of the industry-standard AZ 16 Safety Switch. This model is engineered for guarding applications where larger cabling or standard M20 cable glands are preferred over the smaller M16 standard. Like its counterparts, it features a separate actuator key and utilizes a **30 N Latching Force («R»)** to mechanically hold the guard door in the closed position, preventing nuisance tripping caused by machine vibration.
Technical Specifications and M20 Connectivity
The AZ 16 is constructed from glass-fiber reinforced thermoplastic, making it self-extinguishing and highly durable (**IP 67**).

The defining feature of this SKU is the **M20 x 1.5 cable entry**, which allows for the use of thicker multicore cables often found in heavy industrial installations without the need for thread adapters.

Expert Installation Advice: Gland Selection
Using the correct cable gland is vital for maintaining the IP67 rating. Expert Tip: Since this unit has M20 entries, ensure you purchase M20 polyamide glands with the correct clamping range for your cable diameter. A common mistake is using an M16 gland with a reducer; while possible, it often compromises the seal. Also, ensure the unused entries are sealed with M20 blind plugs (usually included or sold separately) to prevent dust ingress.
Frequently Asked Questions (FAQs)
Q: Is the body size larger than the M16 version?
A: No, the external dimensions of the housing are identical. Only the threaded holes are bored out to M20 specification.
Q: Can I use this for sliding doors?
A: Yes, provided you use the correct actuator (straight or angled) and ensure the door does not have excessive lateral play that could snap the key.
