Limit Switch Roller Lever 10A Snap Action 1NO 1NC AZ-5104 Auspicious

The Auspicious AZ-5104 is a limit switch roller lever unit with a fixed rotary lever that turns through 90 degrees. A cam or moving part presses the roller, the lever rotates, and the snap action mechanism flips the contacts cleanly. Snap action matters because the contacts move fast regardless of how slowly the lever is pushed, which prevents arcing and the pitting that slowly destroys a slow break switch.

The roller itself is what keeps it working over long cycle counts. A plain lever tip scrapes against a passing cam and wears down, shifting the trip point over time. The roller turns instead, so friction stays low and the switch trips at the same point after thousands of operations.

Electrically it handles 10A at 125 or 300V AC resistive, with 1HP switching at 250V AC, enough to drive a small motor directly instead of through a contactor. IP67 sealing means fully dust tight and able to withstand temporary immersion, backed by oil tight construction and stainless steel internals. That combination suits machine tools with coolant, washdown areas and outdoor plant. UL and CE approvals cover it for export equipment.

Common Applications

Cam operated sequencing on machine tools, end of travel stops on slides and carriages, guard and door position detection, conveyor stop positions, small motor switching without a contactor, outdoor material handling equipment, and washdown areas where a lower IP rating would fail.

Related Products

The AZ-5104 has a fixed lever. If you need to set the lever length to suit the target, the AZ-5108 adjustable roller lever limit switch shares the same 10A rating and IP67 body with an adjustable arm. For heavy plant such as lifts and cranes, the AZ-5108L big wheel limit switch uses an oversized roller, and the AZ-5109 ball limit switch takes a direct push from above.

For lighter 5A duty the AZ-8108 adjustable roller lever and AZ-8107 adjustable rod models are more economical.

FAQ,s

What is a roller lever limit switch?

It is a limit switch operated by a lever with a roller at the tip. A moving part presses the roller, the lever rotates, and the contacts change over to signal the controller.

What does snap action mean?

The contacts flip over quickly once the lever reaches its trip point, no matter how slowly it was pushed. That speed reduces arcing and makes the switch last longer.

What is the difference between the AZ-5104 and the AZ-5108?

The AZ-5104 has a fixed lever. The AZ-5108 has an adjustable lever, so you can change its length to reach the moving part without relocating the switch.

Can it switch a motor directly?

Yes, up to 1HP at 250V AC. Larger motors should go through a contactor with this switch driving the coil.

What does IP67 cover?

Fully dust tight, and able to withstand temporary immersion in water. That suits outdoor installations, washdown areas and coolant heavy machine shops.

What does 1NO 1NC mean?

One normally open and one normally closed contact, giving both a position signal and an interlock from a single switch.
