D4N-9131

Snap action limit switches are electrical switches used for a variety of applications. The D4N-9131, in particular, is built for a wide range of industrial, electronic and automotive applications, from quality control and hazard detection to motion control and material handling.

The D4N-9131 is a single-pole, double-throw (SPDT) snap action limit switch with a max voltage rating of 125/250V. It features a contact resistance of 30mΩ minimum, with a mechanical life expectancy of 10 million operations (at full load). The control circuitry is extremely reliable and durable, making it suitable for heavy-use, even in damp and corrosive environments.

The working principle of the D4N-9131 is quite simple. When it is triggered by an external force, the lever arm of the switch moves, closing or opening the circuit depending on how it is set up. In order to trigger the mechanism, the physical force has to be greater than the switch\'s actuation force. Once the external force is removed, the switch returns to its original position and the circuit is reset. This allows the switch to cycle between open and close states many times, making it suitable for a variety of applications.

The D4N-9131 can be used in a variety of applications, such as safety detection, hazard detection, quality control, motion control, material handling and control of machines. In safety or hazard detection applications, the switch can be used to detect when a device is either opened or closed, such as an open door or window. Quality control applications may use the D4N-9131 as a limit switch to monitor when a product has reached a preset number or amount. In motion control systems, the D4N-9131 can be used to control the speed and direction of an actuator or motor. Finally, in material handling or machine control applications, it can be used to detect when an object has reached a certain point in a process.

The D4N-9131 is a reliable and durable limit switch that can be used in a variety of applications. The simple working principle, high voltage rating, contact resistance and mechanical life expectancy make it suitable for both indoor and outdoor applications. It is also easy to install and use, making it a great choice for a variety of commercial, industrial, automotive and electronic projects.
