The Moujen MN-5311 is a mini limit switch that carries a full 10A at 250V AC from a compact side mount body. That combination is the reason to specify it. Most switches this size stop at 5A, so when a panel is tight on space but the circuit still needs real switching capacity, the MN-5311 fills the gap without stepping up to a full size enclosure.

The roller plunger actuator takes a push in line with the body. A cam or moving part presses down on the roller, the plunger travels, and the contacts change over. The roller is what makes it last: a plain plunger head gets scraped by every pass of a sliding cam, which shifts the trip point and eventually jams it, while a roller turns instead.

Side mounting lets the switch sit flat against a frame or bracket so the actuator faces the direction of travel. Oil tight and waterproof construction to IP65 handles coolant, dust and washdown. The operating speed range starts at 0.01mm per second, so it registers very slow creeping movement as well as fast travel up to 50cm per second. UL and CE approvals cover it for export machinery.

Common Applications

Cam sequencing on machine tools, door and guard position detection, end of travel stops on slides and carriages, jig and fixture confirmation, packaging and assembly line positions, vending and dispensing mechanisms, and any tight installation that still needs 10A switching capacity.

Choosing the Right Actuator

The actuator has to suit how the moving part arrives. A roller plunger wants a push in line with the body. Where the approach angle varies, the cross roller plunger switch ME-8122 accepts contact from more than one side.

Where the part passes by rather than pressing down, a lever reaches out to meet it. The lever limit switch AZ-7120 is a compact side mount unit, the adjustable roller lever switch AZ-8108 lets you set the lever length, and the adjustable rod limit switch AZ-8107 reaches irregular targets with a shapeable rod. For contact from any direction without risk of breakage, the spring limit switch AZ-8166 flexes instead.

Heavier duty needs a bigger body. The 10A adjustable roller lever switch AZ-5108 has a metal housing, and the big wheel limit switch AZ-5108L is IP67 rated for lifts and cranes.

FAQ,s

What is a mini limit switch?

A compact position detection switch that signals a controller when a moving part reaches a set point. The smaller body fits inside machinery and tight panels where a full size switch will not go.

Why does the 10A rating matter on a mini switch?

Most switches this size are limited to 5A. The MN-5311 carries 10A at 250V AC, so it can switch heavier control circuits without needing a larger housing or an extra relay.

What is a roller plunger actuator?

A plunger with a roller at the tip. A cam presses down on the roller and pushes the plunger in. The roller turns instead of scraping, which reduces wear and keeps the trip point consistent.

Can this switch connect to a PLC?

Yes. The 0.5A 125V DC rating covers standard 24V DC PLC inputs, and the 10A AC rating lets it switch control circuits directly.

What does side mount mean?

The switch fixes flat against a surface on its side, so it can sit along a frame or bracket with the actuator facing the direction of travel.

Is IP65 suitable for coolant and washdown?

Yes. IP65 with oil tight and waterproof construction resists dust and low pressure water jets, which covers machine tool coolant and routine washdown.
