Roller Lever Type Micro Limit Switch 15A IP55 MJ2-1713 Moujen Taiwan

The Moujen MJ2-1713 is a roller lever micro limit switch from the MJ2 Series, used to detect when a moving part reaches a set position. A cam or dog presses the roller lever, the contacts change over, and the control circuit gets the signal to stop, reverse or move to the next step.

The roller on the lever tip is what keeps the trip point accurate over a long service life. A cam sliding across a bare lever scrapes it, and that wear gradually shifts where the switch operates until it no longer reads the same position twice. The roller turns instead of scraping, so friction stays low and the position stays repeatable through thousands of cycles.

At 15A on 125 or 250V AC it carries far more than a typical 5A micro switch, and the motor ratings mean it can drive a small motor directly rather than going through a contactor. The operating speed range starts at 0.01mm per second, so it registers very slow, precise movement as well as faster travel. IP55 sealing covers dust and low pressure water, suiting workshops, machine shops and general industrial enclosures. Moujen has built industrial switches in Taiwan for decades, so the MJ2 Series is a known direct replacement for machine builders.

Technical Specifications

Common Applications

End of travel detection on conveyors and sliding mechanisms, cam operated sequencing on machine tools, door and guard position confirmation, jig and fixture position sensing, packaging and assembly line stops, small motor switching without a contactor, and repeat cycle work where a plain lever would wear out.

Related Products and Categories

This switch belongs to the limit and micro switches range, where every actuator type and rating can be compared side by side, and to the 15A micro switch group for anything at the same current rating.

If the moving part presses straight down from above instead of across, the roller plunger limit switch AM-1308 shares the same 15A rating with a top plunger head, and the cross roller plunger limit switch ME-8122 accepts a push from more than one direction. Where the lever length needs setting to suit the gap, the adjustable roller lever limit switch AZ-8108 and the adjustable rod limit switch AZ-8107 both allow adjustment. For heavier duty, the 10A adjustable roller lever limit switch AZ-5108 has a metal body with stainless steel internals.

Panel builders fitting these switches also need push buttons and indicators and selector switches and isolators for the control station.

FAQ,s

What is a micro limit switch used for?

It detects when a moving part reaches a set position. The part presses the actuator, the contacts change over, and the signal tells the machine to stop, reverse or start the next step.

Why choose a roller lever over a plain lever?

Because the roller turns instead of scraping. A cam sliding across a bare lever wears it down over time and shifts the trip point, while the roller keeps friction low and the position repeatable.

Can the MJ2-1713 switch a motor directly?

Yes, up to a quarter horsepower at 250V AC or an eighth of a horsepower at 125V AC. Anything larger 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 washdown or coolant heavy areas choose an IP65 or IP67 rated model instead.

Will it replace my existing Moujen switch?

If the current unit is an MJ2 Series roller lever switch, this is a direct replacement. For other brands or series, check the mounting centres and actuator height against your existing switch first.

How slow a movement can it detect?

The operating speed range starts at 0.01mm per second, so it handles very slow and precise travel as well as faster movement up to 1m per second.
