D4SL-N2QFG-D4

Snap Action, Limit Switches are ubiquitous in industrial and commercial applications, making them vital to the efficient and reliable functioning of many mechanical, electrical, and electronic systems. The D4SL-N2QFG-D4 series of switches is often referred to as a “universal” switch because it can be used to control virtually any type of system and motion, including sliding and rotary motion, velocity, force, and position. The D4SL-N2QFG-D4 switch is a toggling reed switch and is part of the larger family of snap-action switches that include microswitches, miniature snap-action switches, and other rigid-motion switches.

The D4SL-N2QFG-D4 switch is a single-pole double-throw (SPDT) switch that enables a circuit, or load, to be switched between two different voltage sources. It is usually used to control the power to an appliance or system, such as a fan, motor, or light. Unlike traditional switches, the SPDT type is designed to “snap” on and off when power is applied or when the circuit is open, thus providing greater assurance that the device will not be damaged, or exposed to hazardous current overloads.

The D4SL-N2QFG-D4 is a great choice for use in harsh and hazardous environments, like oil and gas production sites, remote locations, and Class 1, Division 1 areas. Its impact-resistant NEMA 4X stainless steel housing helps it to resist corrosion, making it more reliable and longer-lasting than other types of switches. It also offers an IP67 watertight rating and is designed to operate in temperatures between -40 and 140 degrees F (-40 to 60 degrees C). The spring-loaded actuator isolates it from vibration and movement while in use, protecting it from accidental operation and enabling it to operate in a single direction.

The most common way that a D4SL-N2QFG-D4 switch is used is as a limit switch that opens or closes a circuit when a predetermined amount of current, voltage, or force is applied to it. In the simplest form, a limit switch can be used to turn a light on and off at a specified time. It can also be used to limit the movement of a conveyor belt or to activate a safety feature that halts a machine if an overload current is detected. In such cases, the switch acts as both an on/off switch as well as a sensor.

The D4SL-N2QFG-D4 switch’s internal contact assembly is designed to reduce the effects of arcing and wear and tear that can occur with other types of switches. It also offers high-current ratings and switching speeds, with contact ratings of 10A at 240VAC and 5A at 250VAC. Switching speeds of up to 1 million cycles per minute make it well suited for high-speed applications. In addition, its hermetically sealed construction protects it from dust and moisture, and it is UL, CE and OSHA rated.

The D4SL-N2QFG-D4 switch is a versatile component that can be used to replace complex circuitry, providing a simple solution for a variety of industrial or commercial applications. Its robust construction, reliable operation, and long life make it a great option for many applications requiring remote or hazardous-duty operation. With its long history of successful operation in many different applications, the D4SL-N2QFG-D4 switch is an excellent choice for controlling electronics, machines, and other systems.
