MAS110A4-RB2 IMO Limit Switch, Miniature Cabled Sealed Piston Plunger

Why Choose the IMO MAS110A4-RB2 Miniature Limit Switch?

The IMO MAS110A4-RB2 is a compact and robust miniature cabled sealed piston plunger limit switch designed for reliable position detection, end-of-travel sensing and mechanical control in industrial machinery and automation systems. As part of the IMO MA miniature limit switch series, it combines a durable metal body with a sealed piston plunger actuator and factory-fitted cable for straightforward machine installation.

The MAS110A4-RB2 features an S11 1NO + 1NC snap-action contact arrangement, providing one normally open and one normally closed switching circuit. Its snap-action mechanism provides rapid contact changeover when the actuator reaches its operating point, while the piston plunger incorporates an external rubber gasket to provide additional sealing around the actuator.

Supplied with a factory-fitted 2 m cable, the MAS110A4-RB2 provides a convenient pre-wired solution for machinery and automated equipment. The actuator has a minimum operating force of 7 N, while the compact metal construction makes this model suitable for installations where dependable mechanical position sensing is required within restricted mounting space.

Reliable Position Detection for Industrial Machinery

Mechanical limit switches such as the IMO MAS110A4-RB2 detect the physical position or movement of machine components. When a moving component depresses the sealed piston plunger, the internal snap-action mechanism rapidly changes the state of the normally open and normally closed contacts, providing an electrical switching signal to the machine control system.

The external rubber gasket around the piston plunger provides additional protection at the actuator interface, making this variant particularly useful where a sealed plunger arrangement is preferred. Combined with its compact metal body and factory-fitted 2 m cable, the MAS110A4-RB2 provides dependable electromechanical feedback for machine sequencing, travel limitation and automated position monitoring.

Typical Applications

• Industrial machinery position detection.
• End-of-travel and overtravel sensing.
• Conveyors and material handling systems.
• Packaging and production machinery.
• Machine tools and automated equipment.
• Mechanical sequencing and control systems.
