Snap action, limit switches are a type of electromechanical device used to monitor and control the opening and closing of a circuit. D2HW-C202M is the latest in the range of snap action, limit switches available to designers. It is a dual-lever switching mechanism that is suitable for a wide variety of applications requiring precise switching control.

D2HW-C202M has two switching functions, one that detects the presence of an object and another that detects the passage of an object. Its contact rating is 5A/120VAC and 1A/60VDC. It has a degree of protection of IP64 and a mechanical life of up to 10 million cycles. The travel distance of the limit switch is 10mm. It also features a ‘push to release’ mechanism for easier operation.

The D2HW-C202M can be used in a variety of applications. It is commonly used in safety circuits, packaging machinery, conveyor systems, machining centers and automated machine tools. It can also be used for door interlocks, access control and to detect the presence or passage of an object. In addition, it can be used as a limit switch for controlling hydraulic or pneumatic systems and for controlling position/displacement of moving objects.

The working principle of the D2HW-C202M is based on the action of two levers. As the object to be detected comes close to the switch, the actuator unit of the switch is moved by the object, causing the two levers to rotate and making contact inside the switch. The contact points close the circuit, allowing the current to flow, which activates the device.

The actuator unit of the D2HW-C202M is a pivoting arm with a magnetic flux detector, which is used to detect the presence and direction of a magnetic field. This in turn triggers the movement of the two levers. When the object approaches the switch, it creates a magnetic field around it which is detected by the detector. The detector relays a signal to the switch, which activates the levers to move and close the circuit.

In addition, the D2HW-C202M has a ‘push to release’ feature. This feature allows the user to manually reset the lever when required. This feature can be used to reset the switch after a fault has been detected or to reset the device in case of a power failure. This feature can also be used to manually override the switch and open the circuit without any power supply.

The D2HW-C202M provides precise switching control and can withstand a wide range of temperatures. Furthermore, it is resistant to shock, vibration and humidity, making it suitable for use in harsh industrial environments. It can also be used with a wide variety of devices and systems. The D2HW-C202M is a reliable and safe switch for a wide range of applications.
