Why Choose the Lovato KBB2A12 Metal Top Roller Plunger Limit Switch?
The Lovato KBB2A12 is a compact and robust metal top roller plunger limit switch designed for reliable position detection and mechanical actuation in industrial machinery and automation systems. As part of the Lovato K series limit switch range, it combines a metal-bodied construction with a top roller plunger actuator for dependable operation in machine control applications.
The KBB2A12 features a 1NO+2NC contact configuration, providing one normally open and two normally closed contacts for flexible signalling, interlocking and control functions. Its slow-action switching arrangement provides defined contact operation as the roller plunger is mechanically actuated by a moving machine component.
The top-mounted roller plunger is particularly suited to applications where a moving component, cam or machine element travels against the switch from above. The roller reduces sliding friction at the point of actuation, while the compact K series format makes the KBB2A12 suitable for installation in machinery where dependable mechanical position sensing and efficient use of space are required.

Reliable Position Detection for Industrial Machinery
Limit switches such as the Lovato KBB2A12 convert the physical movement of a machine component into an electrical switching signal. When a moving component contacts the top roller plunger, the actuator travels and changes the state of the internal contacts, allowing the control system to detect position, confirm movement or initiate another machine function.
The 1NO+2NC slow-action contact arrangement provides multiple circuit possibilities from a single mechanical actuator. This makes the KBB2A12 suitable for applications requiring simultaneous signalling and control functions, including machine sequencing, interlocking, travel limitation and position confirmation.
Typical Applications
- Machine end-of-travel detection.
- Industrial position sensing and monitoring.
- Conveyors and material handling equipment.
- Packaging and production machinery.
- Machine tools and automated equipment.
- Doors, guards and moving machine assemblies.
- Mechanical sequencing and interlocking systems.
- OEM machinery and industrial automation systems.
