Why Choose the Lovato KBF4S02 Limit Switch?
The Lovato KBF4S02 is an industrial K series limit switch with an adjustable roller lever, designed for position detection and motion monitoring in machinery and automated equipment. Its dimensions conform to EN 50047, supporting straightforward integration into standard industrial installations.
This limit switch features 2NC snap-action contacts, providing two normally closed contacts for machine-control, monitoring and interlocking circuits. The adjustable lever incorporates a rubber roller with offset alignment, allowing the actuator position to be adapted to the movement and geometry of the machine.
The KBF4S02 uses a double-insulated thermoplastic housing with IP65 body protection and a bottom M20 cable entry. Its rapid snap-action mechanism, self-releasing screw terminals and adjustable operating head make it suitable for reliable mechanical position detection in demanding industrial applications.
Key Advantages
- Adjustable roller-lever limit switch for industrial machinery.
- 2NC snap-action contacts provide rapid and repeatable switching.
- Rubber roller with offset alignment for adaptable mechanical actuation.
- IP65 thermoplastic housing provides protection against dust and water jets.

Reliable Position Detection for Industrial Machinery
Limit switches convert the physical movement of a machine component into an electrical contact signal. The adjustable lever on the Lovato KBF4S02 allows the roller position to be configured for contact with cams, conveyors and other moving parts, while the rubber roller provides a resilient actuation surface.
The snap-action mechanism changes both normally closed contacts rapidly when the operating point is reached. This switching characteristic supports repeatable position detection where a decisive contact change is required despite gradual actuator movement.
Typical Applications
- Machine position and end-of-travel detection.
- Conveyors and material-handling systems.
- Equipment-status and movement monitoring.
- Packaging and processing machinery.
- Automated production and assembly equipment.
- Cams, lifts and moving mechanical components.
