Why Choose the IMO MAS120A1-RB2 Miniature Limit Switch?
The IMO MAS120A1-RB2 is a compact miniature cabled short plunger limit switch designed for reliable position detection, end-of-travel sensing and machine control in industrial automation applications. Part of the IMO MA miniature limit switch range, it combines a robust metal body with a short plunger actuator for direct mechanical operation by moving machine components.
The MAS120A1-RB2 features an S12 1NO + 2NC snap-action contact arrangement, providing one normally open and two normally closed contacts within a single compact switch. Its snap-action mechanism produces rapid contact changeover when the short plunger reaches its operating point, making it suitable for dependable position feedback and control signalling.
Supplied with a factory-fitted 2 m cable, the MAS120A1-RB2 provides a convenient pre-wired solution for machinery and automated equipment. The short plunger configuration has a minimum operating force of 7 N and uses IMO's Group 1 travel characteristics, providing a compact sensing solution for direct mechanical actuation.

Reliable Short Plunger Position Detection
The IMO MAS120A1-RB2 provides electromechanical position feedback by converting movement of its short plunger into an electrical switching signal. When a moving machine component depresses the plunger sufficiently, the internal snap-action mechanism rapidly changes the state of the 1NO + 2NC contacts, providing signals that can be used by the associated machine control system.
The short plunger actuator is particularly suitable for direct mechanical sensing where the moving component approaches the switch along a controlled path. Combined with its compact metal body and factory-fitted 2 m cable, the MAS120A1-RB2 provides a practical solution for machine sequencing, end-of-travel detection and automated position monitoring.
Typical Applications
- Industrial machinery position detection.
- End-of-travel sensing.
- Machine sequencing and control.
- Conveyors and material handling systems.
- Packaging and production machinery.
- Machine tools and automated equipment.
- Mechanical position feedback systems.
