AZM160-22YP Non-Contact Magnetic Safety Interlock Switch

The AZM160-22YP functions as a magnetic safety interlock switch, designed to monitor the position of movable machine guards such as access doors, gates, or covers. It uses a powerful magnet embedded in the guard to actuate the switch, eliminating mechanical wear and ensuring consistent performance over time. Unlike traditional mechanical switches, its non-contact design reduces the risk of failure due to dirt, vibration, or misalignment—common issues in industrial settings. The switch connects to safety relays or programmable safety controllers via its 22mm round housing with integrated terminals, supporting both normally closed (NC) and normally open (NO) contacts for flexible integration into safety circuits. It features a built-in LED status indicator that provides instant visual feedback on switch status, simplifying troubleshooting.

Main features and advantages:

Choosing the AZM160-22YP delivers clear safety and operational benefits. Its rugged construction—with a metal housing rated IP67 for dust and water resistance—ensures reliable performance in harsh environments, from food processing facilities with washdowns to automotive plants with oil and coolant exposure. The non-contact design eliminates mechanical wear, extending service life and reducing maintenance costs compared to traditional switches. Engineers will appreciate the ease of integration; its compact 22mm form factor fits standard panel cutouts, and the pre-wired M12 connector simplifies installation, cutting setup time by up to 30%. Most importantly, the AZM160-22YP is engineered to minimize nuisance trips, with a generous actuation range that tolerates minor guard misalignment, ensuring that production isn’t interrupted by false safety signals.

Application areas:

The AZM160-22YP excels in applications where safety and productivity are equally critical. In automotive assembly plants, it secures access doors to robotic welding cells, instantly shutting down power if a door is opened during operation while allowing quick restart once the door is closed. In pharmaceutical manufacturing, it monitors the position of cleanroom access panels, ensuring that sterile processes aren’t compromised by unauthorized entry and simplifying compliance with FDA regulations. The switch also performs reliably in packaging machinery, where it guards access to high-speed rotating parts, preventing injuries while enabling fast changeovers for different product runs. In each case, the AZM160-22YP provides the safety integrity needed to protect workers without sacrificing operational efficiency.

Installation and maintenance:

Before installing the AZM160-22YP, verify that the mounting surface is flat and free of debris to ensure proper alignment with the magnet. Check that the safety circuit voltage matches the switch’s 24V DC rating, as overvoltage can damage internal components.

During installation, confirm that the magnet is positioned within the switch’s actuation range (typically 10-15mm) to ensure reliable operation—use the LED indicator to test alignment, as a steady green light confirms proper actuation. For ongoing maintenance, inspect the switch and magnet quarterly for signs of physical damage or contamination, especially in washdown areas where chemicals may degrade seals. Every year, perform a functional test using a safety relay to ensure that the switch triggers a shutdown within the required response time, maintaining compliance with safety standards.
