D4N-3131

Snap Action, Limit Switches

The D4N-3131 series of limit switches is a type of snap action switch that uses mechanical force to open and close the electrical circuit. The switch operates using a lever mechanism, where a spring-loaded arm moves to either break or make contact with the terminals. It is usually used with a maximum voltage of 250VAC and a maximum current of 5A, making it suitable for lower power applications. The switches are designed to provide a reliable, repeatable, and economical electrical switching solution in many types of equipment, such as machine tools, production machinery, assembly line equipment, and food processing machines.

Operating Mechanism

The D4N-3131 series switch is operated by a lever and spring-loaded actuator that is attached to the main body of the switch. When the actuator is moved to the operating position, the spring-loaded arm is activated, which moves the contact to either make or break the electrical circuit. As the arms move, a mechanical movement occurs, which produces an audible click and a tactile feeling when the contacts are operated. The switches are designed with a positive opening action, ensuring that the contacts are not accidental and are always reliably actuated.

Design Features

The D4N-3131 series switch has many design features that ensure reliable performance and longevity. The adjustable snap action mechanism is designed to maintain consistent, repeatable operation over millions of cycles. The switch has a high degree of protection against shock and vibration, making it suitable for use in harsh industrial environments. Its terminal construction ensures reliable contact and is designed to resist corrosion and oxidation. The switch is also UL approved, making it suitable for installation in hazardous locations.

Applications

The D4N-3131 series switch is suitable for a wide range of applications, due to its strong construction and reliable operation. It is suitable for use in the control and monitoring of heavy machinery, production machinery, and assembly line equipment. It is also often used to control and monitor pumps, conveyor belts, and packing lines in food processing and beverage industries. The switch is also Rugged enough to be used outdoors, making it suitable for door locks, gutters, and fire systems as well.
