Snap action, limit switches are widely used in industrial automation and process control system. The GKRA40F4C2-F05-C limit switch is one such device that is widely used in these industries. It is designed for applications such as on/off control of valves, pumps, fans, motors, and other industrial equipment. In this article, we will discuss the application field and working principle of the GKRA40F4C2-F05-C limit switch.

Application Field:

The GKRA40F4C2-F05-C limit switch is designed and manufactured for applications in industrial automation, process control, and safety systems. This industrial limit switch is most often used in systems that require reliable on/off control of valves, pumps, fans, motors, and other equipment. It is also commonly used in safety circuits to detect safe conditions such as open/closed doors or gates. Other applications include isolating and controlling electric circuits, as well as controlling material flow in equipment such as conveyors, lifts, and elevators.

Working Principle:

The GKRA40F4C2-F05-C limit switch is a magnetic reed switch. A magnetic reed switch consists of two reed contacts that are sealed in an inert gas and encased in a plastic housing. When the switch is energized, a magnetic field builds up around the reed contacts, attracting them together and closing the circuit. When the switch is de-energized, the magnetic field dissipates and the reed contacts separate, opening the circuit. When a magnetic object, such as a door or gate, comes within range of the reed contacts, it triggers the switch, activating the circuit.

The GKRA40F4C2-F05-C limit switch is designed to withstand harsh industrial environments. It is rated IP67 and is rated for temperatures ranging from -40°C to +85°C. It has a contact resistance of 25mΩ~50mΩ and insulation resistance of 100MΩ and is rated at 250VAC and 500VDC.

The GKRA40F4C2-F05-C limit switch is a robust, reliable, and highly effective solution for on/off control jobs in industrial applications. It is easy to install, easy to use, and offers reliable long-term performance.
