Snap-action limit switches, also known as microswitches, are popularly used in a variety of industrial applications and have become an integral part of many industrial automation processes. The D4NL-2DFG-B is a type of snap-action limit switch that is widely used in different industries for various tasks. The D4NL-2DFG-B is a reliable and cost-effective solution for industrial automation needs.

Application Fields

The D4NL-2DFG-B snap-action limit switch is widely used in automatic machinery and process control systems. It is suitable for use in a wide range of applications, such as printing and packaging, textile, pharmaceutical, food and beverage, and automobile industries. The switch is also widely used in the HVAC industry, as well as in industrial automation, machine tools, and robotic systems. The switch is also used in hazardous environments, such as high-temperature and pressure applications, as well as in corrosive workspaces. Furthermore, the device can be used in outdoor applications, where the device is subject to rain, snow, and other weather conditions.

Working Principle

The D4NL-2DFG-B snap-action limit switch is a quickly-acting switch with a highly sensitive contact mechanism and is triggered by the movement of a plunger or roller, resulting in an immediate “snap” action. The switch is commonly used to detect the end of travel of the actuator in a system or to detect the presence of an object or material. The switch requires a fixed or adjustable travel distance for proper operation. The switch is adjustable with a manually operated or motorized potentiometer, allowing the user to adjust the sensitivity of the switch. The range of motion is adjustable to include a pick-up and a drop-out position.

The switch has a basic construction that consists of a spring-mounted actuator, a moving contact arm, and a stationary contact. When the actuator is energized, the contact arm snaps to the stationary contact, completing the circuit. The switch is designed to operate in a wide range of temperatures, typically −25°C to 70°C (−13°F to 158°F). The switch also has a wide range of electrical ratings, from 0.4A to 16A, with standard ratings of 0.4A/125V to 6A/250V AC/DC.

The D4NL-2DFG-B provides a quick, reliable, and cost-effective solution for industrial automation needs. Its quick action and adjustable sensitivity make it an ideal choice for a wide range of applications. The device is easy to use and maintain, making it an attractive option for industrial automation.
