MSSTC11DA15 IMO Microswitch, Screw Terminals Roller Piston Plunger In-line

Why Choose the IMO MSSTC11DA15 Microswitch?

The IMO MSSTC11DA15 is a compact and durable industrial snap-action microswitch designed for mechanical position detection, end-of-travel sensing and machine control applications. As part of the IMO MSS microswitch series, it features an in-line roller plunger actuator with M12 threaded neck, snap changeover contacts and robust glass-reinforced plastic construction.

The MSSTC11DA15 uses a snap-action switching mechanism to provide fast and repeatable contact operation when the roller plunger is mechanically actuated. Its in-line roller reduces sliding friction between the actuator and moving machine components, while the M12 threaded neck provides a convenient method of positioning and securing the switch within industrial machinery.

Featuring 1 NO + 1 NC changeover contacts, the MSSTC11DA15 provides both normally open and normally closed switching functions. Its actuator has 0.5 mm pretravel, 5.5 mm overtravel and a maximum operating force of 4 N, providing controlled mechanical operation for automation equipment, machine tools and OEM machinery.

Reliable Mechanical Switching for Industrial Equipment

Microswitches provide an electrical signal when mechanical movement reaches a predetermined position. The IMO MSSTC11DA15 uses an in-line roller plunger and snap-action mechanism to operate its changeover contacts, enabling machinery and control systems to detect component position, identify end-of-travel conditions or initiate another stage of an automated process.

The roller plunger is particularly useful where a moving component passes across the actuator because the rotating roller helps minimise sliding friction and wear at the contact point. Combined with its M12 threaded neck, defined actuator travel and durable MSS series construction, the MSSTC11DA15 provides a practical solution for repetitive position-sensing duties in industrial machinery.

Typical Applications

• Industrial machinery position detection.
• Mechanical limit and end-of-travel sensing.
• Conveyors and material handling equipment.
• Automated production machinery.
• Machine tools and processing equipment.
• Packaging and assembly machinery.
• Control and interlocking mechanisms.
• OEM machinery and automation systems.
