Roller Plunger Push Type Micro Limit Switch 15A IP55 MJ2-1308 Moujen Taiwan

The MJ2-1308 from Moujen Taiwan is a roller plunger push type micro limit switch from the MJ2 series. A cam or moving part presses straight down onto the roller at the top of the plunger, the plunger travels, and the contacts switch over to signal the controller.

Specify this model when you are replacing an existing MJ2-1308 or need a 15A roller plunger switch in a compact body. The roller is the part that earns its place in repeat duty. A cam sliding across a bare plunger head wears it down, shifting the trip point over time, while a roller turns instead of scraping and holds the same trip point for far longer.

It handles 15A at 125 or 250V AC, with motor switching at an eighth of a horsepower on 125V AC and a quarter horsepower on 250V AC, so small drives can run from the switch directly. IP55 sealing covers dust and low pressure water for normal machine and workshop conditions. UL Listed and CE Mark certified, manufactured in Taiwan by Moujen.

Specifications

Typical Uses

Cam operated sequencing on machine tools, end of travel stops on slides and presses, door and guard position detection, jig and fixture confirmation, conveyor stop positions, and small motor switching without a contactor.

Other Options in This Range

Full range of actuators, ratings and IP grades is on the Limit and Micro Switches page, and all 15A models sit together under 15A Micro Switch.

If you need the same roller plunger action in a different body, the AM-1308 roller plunger limit switch from Auspicious is also 15A at IP55. For angled approach, the ME-8122 cross roller plunger limit switch is the Moujen 5A IP65 alternative.

Where the part arrives from the side rather than from above, use a lever: the AZ-8108 adjustable roller lever mini limit switch at 5A, the AZ-5108 adjustable roller lever limit switch at 10A, or the AZ-8107 adjustable rod limit switch for long reach onto an irregular target.

FAQ,s

What is the MJ2-1308 used for?

It detects when a moving part reaches a set position. A cam presses the roller plunger, the contacts change over, and the machine stops, reverses or moves to the next step.

Why a roller plunger instead of a plain plunger?

A roller turns rather than scraping. A sliding cam wears down a plain plunger head over thousands of cycles, which moves the trip point and can eventually jam it.

Can it switch a motor directly?

Yes, up to an eighth of a horsepower at 125V AC and a quarter horsepower at 250V AC. Larger motors should run through a contactor with the switch driving the coil.

Is IP55 enough for a workshop?

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

What is the difference between the MJ2 and ME series?

MJ2 is the 15A micro limit switch family in a standard body. The ME series covers the 5A mini switches in a smaller housing for tighter spaces.

Do you ship MJ2-1308 outside the UAE?

Yes. Choose your destination at checkout and shipping is calculated there.
