Top Plunger Push Limit Switch 10A IP65 AZ-7100 Auspicious

The Auspicious AZ-7100 is a top plunger push type limit switch, meaning the actuator is a smooth plunger on the top face that the moving part presses straight down onto. There is no lever to catch and nothing sticking out sideways, so it fits in tight spaces where a lever switch could not be installed at all.

A top plunger push action gives the most precise trip point of any actuator type. The plunger moves in a straight line with no lever arm to introduce play, and the snap action mechanism inside flips the contacts cleanly rather than letting them drift across as the plunger travels. For jigs, fixtures and tooling where the switch has to trip at the same millimetre every cycle, that repeatability is the reason to choose a plunger over a lever.

The operating speed range starts at 0.01mm per second, so the switch registers even very slow creeping movement, and runs up to 50cm per second for faster lines. It is rated 10A at 250V AC and 0.5A at 125V DC, enough for direct AC control switching or a DC signal into a PLC. The oil tight, waterproof IP65 body handles coolant, dust and washdown, and the side mount design lets it bolt flat against a machine frame. UL and CE approvals cover it for export equipment.

Common Applications

Jig and fixture position confirmation, tool and die presence detection, guard and cover closed interlocks, slide and carriage end stops on machine tools, small door and hatch switches, precision assembly stations, and any tight installation where a lever or roller would not physically fit.

Choosing the Right Limit Switch Actuator

The actuator has to match how the moving part arrives, so start there rather than with the price. A top plunger needs the part to press straight down onto it. If the approach is from the side or at an angle, the lever limit switch AZ-7120 reaches out to meet it and shares the same side mount body and IP65 rating.

Where a cam slides across the actuator repeatedly, a roller stops the wear a bare plunger would suffer. The roller plunger limit switch AM-1308 puts a roller on the plunger head and carries 15A, while the cross roller plunger limit switch ME-8122 accepts a push from more than one direction.

For adjustable reach onto an irregular target, the adjustable rod limit switch AZ-8107 and the adjustable roller lever limit switch AZ-8108 let you set the lever length. Where an overrun could snap a rigid actuator, the spring limit switch AZ-8166 flexes and returns. For heavy plant such as lifts and cranes, the big wheel limit switch AZ-5108L has an IP67 body and a wide contact face.

FAQ,s

What is a top plunger push type limit switch?

It is a limit switch whose actuator is a plunger on the top face. The moving part presses straight down on the plunger, which operates the contacts inside. There is no lever or roller sticking out from the body.

When should I choose a plunger instead of a lever?

Choose a plunger when the part presses straight onto the switch and you need a precise, repeatable trip point, or when space is too tight for a lever. Choose a lever when the part arrives from the side or you need extra reach.

What does snap action mean?

The internal mechanism flips the contacts over quickly once the plunger passes a set point, rather than letting them separate slowly. This gives a clean switching signal and reduces arcing at the contacts.

Can this switch connect directly to a PLC?

Yes. The 0.5A 125V DC rating covers standard 24V DC PLC inputs, and the 10A 250V AC rating allows direct switching of AC control circuits.

Is IP65 enough for a machine shop?

Yes. IP65 with oil tight and waterproof construction resists dust, coolant and low pressure water jets, which covers normal machine shop and workshop conditions.

How slow a movement can it detect?

From 0.01mm per second, so it registers very slow creeping travel as well as faster movement up to 50cm per second.
