Purchase now: Schmersal 101172009 AZ 15 Safety Switch
Purchase now: Atlantech Drives provides you the Schmersal 101172009 (Model: AZ 15 ZVK-M16-2254), a specialized variant of the compact AZ 15 series. While standard safety switches have zero retention when unlocked, this «2254» version features a built-in **Latching Force of 5 N**. This light retention is sufficient to keep a lightweight guard door closed against airflow or minor machine vibrations, preventing «nuisance trips» where the machine stops just because the door drifted open by a few millimeters.
Technical Specifications and Compact Design
The AZ 15 is designed for space-constrained applications. The enclosure is made of glass-fiber reinforced thermoplastic (**IP 67**), making it resistant to harsh industrial environments. The «ZVK» configuration offers **1 NO (Signaling) and 1 NC (Safety)** contact. The **M16 cable entry** ensures compatibility with standard small glands. The switch head can be rotated to allow for top, bottom, front, or rear actuation, offering maximum installation flexibility.

Expert Installation Advice: The «2254» Ball Latch
Users often wonder why the actuator «clicks» when inserted. Expert Tip: This is the ball latch mechanism working. It is not a safety lock (you can pull it open by hand), but it is a convenience feature. When installing, ensure the door hinges are aligned so the actuator enters the switch straight. If the door sags, the friction on the 5N latch will increase, potentially causing the plastic actuator to wear prematurely. Use the slotted holes to fine-tune the position annually.
Frequently Asked Questions (FAQs)
Q: Does it fit the same footprint as AZ 16?
A: Yes and no. The mounting holes are the same spacing (center-to-center), but the AZ 15 is physically smaller/slimmer than the AZ 16.
Q: Is the actuator included?
A: No, you must select the correct actuator (e.g., AZ 15/16-B1) based on your door radius.
