The Auspicious AZ-4112 is a wheel limit switch that arrives prewired with a 2.9 metre cable already sealed into the body. There is no terminal chamber to open, no gland to fit and no cable entry to seal on site. You mount the switch, run the cable back to the panel and connect three cores, which is the whole installation.

That matters more than it sounds. On a conventional limit switch the IP rating depends on whoever closes the lid and tightens the gland. A badly fitted gland or a cross threaded cover turns an IP67 switch into a water trap. With a factory sealed cable, the seal is made in the factory and stays made, so the IP67 rating holds in rain, washdown and dusty plant regardless of how the install goes.

The roller plunger actuator takes a cam or moving part pressing down in line with the body, and the wheel turns rather than scraping, so the trip point stays consistent over long cycle counts. Contacts are wired COM, NO and NC, giving both a position signal and an interlock from one device. Ratings are AC15 at 5A 250V AC for inductive control loads such as contactor coils, and DC12 at 5A 30V DC for resistive DC circuits and PLC inputs.

Common Applications

Outdoor gate and barrier position detection, car park and industrial door systems, conveyor end stops in washdown areas, pump and tank level float arrangements, agricultural and irrigation equipment, mobile plant and trailers where a junction box would be impractical, and any position sensing point exposed to water, dust or site conditions.

Choosing the Right Wheel Limit Switch

Two things separate the models: wheel size and how the switch connects. If the moving part is large or arrives with play, such as a lift car or crane trolley, the big wheel limit switch AZ-5108L has an oversized roller on an adjustable 90 degree lever and a higher 10A rating, though it uses terminal connections rather than a cable. The ball limit switch AZ-5109 shares that 10A IP67 body with a top ball plunger for straight down actuation.

Where the environment is drier and a terminal connection is acceptable, the smaller options cost less. The adjustable roller lever limit switch AZ-8108 and the adjustable rod limit switch AZ-8107 cover 5A duty at IP65, the lever limit switch AZ-7120 is a compact side mount unit, and the roller plunger limit switch AM-1308 carries 15A. For contact from any direction, the spring limit switch AZ-8166 flexes rather than breaking on an overrun.

FAQ,s

What is a wheel limit switch?

It is a position switch operated by a roller wheel. When a moving part presses the wheel, the plunger moves and the contacts change over, signalling the controller that the part has arrived.

Why choose a switch with a prewired cable?

Because the seal is made in the factory rather than on site. There is no gland to fit or cover to close, so the IP67 rating is not affected by installation quality, and wiring is faster.

How long is the cable?

2.9 metres, which usually reaches a local junction box or control station. For longer runs, join the cable in a sealed box rather than stretching it.

What do AC15 and DC12 mean?

They are utility categories. AC15 covers switching inductive AC loads such as contactor coils, and DC12 covers resistive DC loads such as PLC inputs and indicator circuits.

Is IP67 suitable for outdoor use?

Yes. IP67 means fully dust tight and able to withstand temporary immersion, so rain, washdown and splashing are not a problem.

What does COM NO NC mean?

Three connections: a common terminal, a normally open contact and a normally closed contact. That gives you both a make signal and a break signal from one switch.
