D4N-822G is a type of Snap Action, Limit Switches. It is used in both industrial and commercial applications where durable, reliable and easy to use equipment is necessary. In many applications, such as machinery, machine tools, and processes, these switches are used to trigger an action when an operator presses a button or switch.

The D4N-822G consists of a moving contact, known as the “actuator”, which is normally open and a stationary contact, the “target” plate. In normal operation, the actuator remains open, until the operator pushes it against the target plate. When this occurs, the current is allowed to flow through and the circuit is complete.

In this configuration, the limit switch serves as a monitor to detect over-travel and/or under-travel in process control applications. In other words, it serves as a limit on the movement, allowing adjustments to be made should the equipment move beyond their preset limits.

The snap action component of this switch is known as the “snap-back” feature. When the actuator is pushed against the target plate, the switch will snap to the next position and quickly return to the open position. This allows for rapid response to an operator’s inputs and ensures that the switch always returns to the same, predetermined position when it is actuated.

In addition to its simple operation, the D4N-822G is also extremely durable, being made of a durable, stainless steel body and a rugged, impact resistant rubber seal, ensuring maximum protection against dirt, dust, moisture, and other corrosive agents.

Most importantly, the D4N-822G is able to operate in a variety of environments. This includes temperatures ranging from -40 to 85° C, as well as a wide variety of operating pressures, including up to 5 psi. This makes it suitable for a variety of applications, including those using hazardous or explosive atmospheres.

The D4N-822G is a popular choice for many industries, including process control, robotics, and packaging. Due to its robust construction, ease of use, and excellent performance, the D4N-822G is one of the most reliable and cost effective snap action, limit switches available.
