D4N-4A31

The D4N-4A31 is a type of snap-action limit switch with a variety of uses in industrial settings. It is a commonly used industrial switch for controlling motors, pumps and other industrial machinery. It is designed to be reliable and cost-effective, making it an ideal choice for applications that require dependable operation at a budget-friendly price.The D4N-4A31 is a solder lug–mounted, single-pole, single-throw (SPST) snap action switch that can be used as a general-purpose industrial safety switch. It has a variety of applications and can be used in many types of machinery, such as conveyor systems, printing presses and printing machines, packing machines, etc. It is also used to control temperatures, heating, cooling and other processes.The operating principle of the D4N-4A31 is based on a snap-action mechanism. When the plunger is actuated, it snaps back, which in turn activates the armature of the switch and ultimately triggers the closing or opening of the contacts. This actuation process is known as a “snap-action”, and it is the characteristic that gives this switch its name.The D4N-4A31 has also been designed to perform reliably over a wide range of temperatures, from -40°C to +125°C. This means that it can be used in a variety of industrial settings, from temperatures as low as a cold store to temperatures as high as a laboratory setting. Besides, it is made from durable and reliable materials, making it suitable for use in extreme conditions such as vibration and mechanical shock environments.The D4N-4A31 is a versatile switch that can be used in a variety of applications. Its most common applications include motor control, position sensing, machine protection, and process control. In motor control, it can be used to control the starting and stopping of the motor. In position sensing, the switch is used to detect when a certain limit is reached. In machine protection, it can be used to detect when a machine’s operating speed exceeds a certain limit and shut it down accordingly. And in process control, it is used to automate certain processes, such as material flow, heat exchange, and so on.Overall, the D4N-4A31 is a reliable and cost-effective snap-action limit switch with a variety of uses. It is highly durable and capable of performing reliably in a wide range of temperatures, from -40°C to +125°C. It is suitable for applications such as motor control, position sensing, machine protection and process control.
