Wobble Stick Limit Switch Coil Spring Actuator 1NO 1NC 5A IP65 AZ-8167 Auspicious

The Auspicious AZ-8167 is a wobble stick limit switch fitted with a flexible coil spring actuator. Unlike a roller lever or plunger that only responds to movement along one path, the spring can be deflected from any direction through 360 degrees. Push it, brush it or bump it from any side and the contacts change over, then the spring returns the actuator to centre once the object passes.

That omnidirectional action is what makes a wobble stick limit switch the right choice where targets do not arrive on a fixed line. Products on a conveyor that drift sideways, loads swinging on a hoist, or parts dropping into a bin all trip it reliably. The flexible spring also absorbs overtravel and impact, so a heavy or fast moving object will not snap the actuator the way it might break a rigid lever.

Inside, one normally open and one normally closed contact give a clean changeover signal for a PLC input, relay or contactor. The switch is rated 5A at 250V AC and 0.4A at 115V DC on resistive loads. An IP65 sealed, oil tight body with stainless steel parts keeps dust, coolant and washdown water out, so it holds up on machine tools and in wet processing areas. CE marked and made in Taiwan.

Common Applications

Product detection on conveyors where items arrive off centre, bin and hopper level sensing, crane and hoist overtravel detection, package and carton counting, door and guard position sensing, jam detection on packaging lines, and any machine where the target can approach the switch from more than one direction.

Choosing the Right Mini Limit Switch

The actuator is the main decision, and it depends on how the target meets the switch. A wobble stick suits random directions. Where the target always travels along one path, a lever or plunger gives more precise switching.

The adjustable roller lever limit switch AZ8108 suits cams and moving parts that roll past on a fixed line, with a lever you can set to the right angle. The adjustable rod limit switch AZ8107 uses a long rod that reaches targets further from the switch body. For direct push action from the front, the cross roller plunger limit switch ME-8122 from Moujen handles sliding cams in either axis.

FAQ 

What is a wobble stick limit switch?

It is a limit switch with a flexible spring or stick actuator that can be deflected from any direction. When an object pushes the spring, the internal contacts change over, and the spring returns to centre once the object moves away.

When should I use a wobble stick instead of a roller lever?

Use a wobble stick when the target can approach from different directions or its path is not fixed. A roller lever is better when the target always travels along the same line and you need precise, repeatable switching.

What does 1NO plus 1NC mean?

The switch has one normally open and one normally closed contact. When the actuator is deflected, the NO contact closes and the NC contact opens, giving a changeover signal to a PLC, relay or contactor.

Can it switch a motor directly?

No. The 5A rating is for resistive loads. For motors and other inductive loads, use the switch to drive a relay or contactor coil instead.

What does IP65 mean for a limit switch?

IP65 means the body is fully dust tight and protected against low pressure water jets from any direction, so it suits machine tools with coolant and washdown areas.
