Top Plunger Push Type Micro Limit Switch 15A IP55 AZ-1307 Auspicious

The Auspicious AZ-1307 is a micro limit switch with a top plunger push actuator. The plunger sits flat on top of the body, so a cam, door edge or moving part presses straight down onto it. No lever, no roller, nothing sticking out that can be knocked out of line.

That simplicity is the reason to pick it. Where the moving part comes down square onto the switch every cycle, a plain plunger is the most compact and precise option available. Detection starts at 0.01mm of travel, so it will pick up very small, slow movement that a lever actuator would miss. It also fits where nothing else will, since the actuator adds almost no height to the body.

At 15A on 125 or 250V AC it carries three times the current of a typical 5A micro switch, and the quarter horsepower rating lets it drive a small motor directly instead of through a contactor. IP55 protection covers dust and low pressure water, which suits indoor machine and workshop conditions. UL and CE approvals cover it for export machinery.

Technical Specifications

Common Applications

Door and cover position detection, cam operated sequencing on machine tools, jig and fixture confirmation, vending and dispensing mechanisms, press and slide end stops, small motor switching without a contactor, and any tight space where a lever or roller would not fit.

Choosing the Right Limit Switch Actuator

The actuator has to suit how the moving part arrives. A plain plunger is right when the contact comes straight down and repeats accurately. If a cam slides across the actuator instead of pressing onto it, choose the roller plunger limit switch AM-1308, which shares the same 15A rating but adds a roller so the cam does not wear the plunger head.

Where the part approaches from the side, a lever reaches out to meet it. The lever limit switch AZ-7120 is a compact side mount option, the adjustable roller lever limit switch AZ-8108 lets you set the lever length, and the adjustable rod limit switch AZ-8107 gives long reach onto irregular targets. For contact from any direction, the spring limit switch AZ-8166 flexes instead of breaking. For heavy equipment such as lifts and cranes, the big wheel limit switch AZ-5108L is IP67 rated with a wide contact face.

FAQ,s

What is a top plunger push type micro limit switch?

It is a position detection switch where the actuator is a plunger on top of the body. A moving part presses straight down on it, the contacts change over, and the controller gets the signal.

When should I use a plain plunger instead of a roller?

Use a plain plunger when the part presses straight down in the same spot each cycle. If a cam slides across the actuator, use a roller so it rolls rather than scrapes.

Can it switch a motor directly?

Yes, up to a quarter horsepower at 250V AC. Anything larger should go through a contactor with the switch driving the coil.

How small a movement will it detect?

Operation starts at 0.01mm of plunger travel, so it picks up very fine and slow movement as well as faster travel up to 1m per second.

Is IP55 enough for my application?

IP55 resists dust and low pressure water, which covers most indoor machine and workshop use. For washdown, coolant or outdoor conditions choose an IP65 or IP67 rated model.

Does this switch come with a catalog?

Yes, the full micro switch catalog is linked above with dimensions and contact data.
