D4N-9A31R

Depending on the type of application, snap action, limit switches are available in several different styles and capabilities. A popular style is the D4N-9A31R. This switch is a multiple pole, single throw type with a mechanical actuating element that is a ball plunger or roller lever. While designed for industrial applications, this switch can be used in a wide range of environments where durability and long service life are preferred.

The D4N-9A31R snap action, limit switch employs a mechanical plunger that is spring-loaded and when released, contacts on a terminal contact block. The contact block is rated for 15 amperes at 125/250 VAC. In the normally open configuration, an electrical current is unable to pass through the switch until the plunger is mechanically actuated provided there is sufficient force to depress the actuating element past the contact point. Conversely, in the normally closed state, the electrical current is able to pass through the switch until the plung is actuated. Once the plunger is actuated, the electrical current is disrupted, providing the desired electrical triggering feature.

The D4N-9A31R is a momentary switch, meaning that the plunger must always be depressed to maintain the electrical connection. In addition to the 15 amperes at 125/250 VAC, the switch is also UL listed for 10 amperes at 32 VDC. An optional low voltage rating is also available for 2.5 amperes at 20 VDC. The switch also carries an IP rating of IP50 for dust protection, making it a suitable switch for many applications.

The D4N-9A31R snap action, limit switch is used in a wide variety of industrial and commercial applications. Typical uses include conveyors, production machines, electric motors, elevators, and industrial fans. The switch is known for its reliable operation and long service life, making it a preferred choice for many applications. In addition to its use as a limit switch, the D4N-9A31R is also used as an emergency stop switch, a machine sequence switching system, and a wide range of other applications.

The D4N-9A31R snap action, limit switch is a reliable and cost-effective switch for a wide range of applications. Its long service life and affordability make it a preferred choice for many applications. The mechanical actuating element requires manual resetting, eliminating the need for frequent replacements. When used in industrial applications, the switch provides a reliable and cost-effective solution for providing electrical triggering when needed.
