The Moujen MN-5120 is a lever type mini limit switch from the MN series of side mount switches. The body fixes flat against a surface and the lever reaches out sideways, so it sits along a machine frame or guide rail where a top actuated switch would not fit.

The lever handles approach from the side and tolerates small alignment errors, which makes it a practical fit for conveyors, sliding doors and carriage travel limits. The 10A 250VAC rating allows direct AC control switching, while 0.5A at 125VDC covers DC inputs into a PLC. The oil tight and waterproof IP65 body holds up in machine shops and washdown areas, and UL and CE approvals cover it for export machinery.

Related Side Mount and Mini Limit Switches

For the same side mount lever duty from a different brand, the Auspicious AZ-7120 lever limit switch is the direct alternative. Where the lever length needs setting, the adjustable roller lever limit switch AZ-8108 adds a roller, and the adjustable rod limit switch AZ-8107 gives longer reach onto irregular targets. For a push straight onto the head, the cross roller plunger limit switch ME-8122 is the Moujen plunger option, and for heavier equipment the 10A adjustable roller lever limit switch AZ-5108 has a larger metal body.

FAQ,s

What is a side mount limit switch?

It fixes flat against a surface with the actuator facing sideways, so the switch can sit along a machine frame or rail and meet the moving part from the side rather than from above.

What does 1NO 1NC mean?

One normally open and one normally closed contact. When the lever operates, the NO closes and the NC opens, giving a position signal and an interlock from one device.

Can it connect directly to a PLC?

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

Is the MN-5120 suitable for wet or oily areas?

Yes. The IP65 oil tight and waterproof body suits machine tools with coolant, conveyors and washdown areas.

What is the alternative if the MN-5120 is out of stock?

The Auspicious AZ-7120 is the closest substitute with the same lever actuator and side mount body at a similar rating.
