D4SL-N4DFA-N

D4SL-N4DFA-N is a type of snap action, limit switch. It is used for sensing and controlling industrial equipment, automatically starting and stopping operations when predetermined limits are reached. By accurately detecting the position of moving parts, it can also be used to monitor shaft speed and acceleration. The switch is also suitable for use in hazardous locations.

The D4SL-N4DFA-N is a miniature limit switch, designed to fit in tight spaces and weighing only 2.5 ounces. It has a metal bellows plunger actuator that snaps back into place when the limits of the switch are detected, providing reliable and accurate operation. The switch is rated up to 3 amps and 125 VAC, and features a robust IP65 enclosure. It has a maximum operating temperature of 210°F, and an operating life of 10 million cycles.

The working principle of the D4SL-N4DFA-N is fairly straightforward. When the plunger is pressed, it triggers the switch, which changes state from open to closed. When the plunger is released, it snaps back into place, triggering the switch to open again. This provides a reliable mechanism for controlling machinery and detecting position limits without the need for human intervention.

The most common application of the D4SL-N4DFA-N is in the automation of industrial machinery. For example, when the switch is wired to a motor, it can be used to detect when a preset position limit has been reached. This allows the motor to automatically stop without the need for human supervision. Additionally, the switch can be used to detect acceleration and deceleration of a motor, allowing it to be regulated for safety purposes.

The D4SL-N4DFA-N is also suitable for use in hazardous locations. It is rated for NEMA 4x and IP67 standard, and is UL certified for wet and hazardous locations. This makes it ideal for use in industrial and petrochemical environments, where the switch needs to be able to withstand extreme temperatures, humidity, and dust.

Overall, the D4SL-N4DFA-N is a versatile, reliable, and compact limit switch, suitable for a broad range of applications. Its simple, reliable working principle combined with a robust housing make it ideal for use in industrial and hazardous applications, while its miniature size allows it to fit into tight spaces. With its certification for hazardous locations, it is the perfect choice for any application that requires a reliable and accurate switch.
