When it comes to industrial safety, bulk shouldn't be the price you pay for protection. That’s why Schmersal’s latest combo — the AZM40 solenoid interlock paired with the DHS door handle — is making waves with machine builders and automation engineers. Especially if you’re designing compact machines or working in tight spaces, this slick setup might be exactly what your project needs.
Why the AZM40 Is a Game-Changer in Machine Safety
At just 16mm deep, the AZM40 is the slimmest solenoid interlock on the market. But don’t let the size fool you — this little device delivers a serious punch with 2,000 newtons of holding force. That means it’s staying locked until you say otherwise. No accidental access. No compromise on safety.
But what really makes the AZM40 stand out? Universal actuation. Its bidirectional design allows the actuator to engage from either side, making it perfect for both hinge and sliding doors, whether they're left- or right-handed. This small feature brings a big benefit for OEM flexibility. You no longer have to design around your safety hardware — the AZM40 adapts to you.
Add the DHS Handle — A Total Safety Interface
Safety that’s sleek is good. Safety that’s intuitive? Even better. The DHS door handle was purpose-built for seamless integration with the AZM40. Operators get a single point of interface: turn the handle, open the door, and the interlock engages or disengages smoothly. There’s even a mechanical override built in — a must for emergency access or routine maintenance. This means fewer components, cleaner design, and less wiring complexity — all without sacrificing functionality or safety compliance.
Where Safety Meets Space Constraints
You already know space is a premium on modern factory floors. That’s why the AZM40 + DHS combo is engineered specifically for applications where compact design is non-negotiable.
Think of systems like:
-
Packaging machines
-
Automated assembly cells
-
Test stands
-
Robotics enclosures
-
Small-footprint conveyors and guarding panels
In these environments, every millimeter matters — but so does safety. The AZM40’s ultra-slim form factor integrates easily into tight machine frames, while the DHS handle keeps operations user-friendly for technicians and operators.
