Snap action limit switches are a type of switch that utilize rapid, discrete movement to register changes in G force, mechanical force, position, and temperature. Recognised for their ability to switch in as little as one millisecond, snap action limit switches offer fast, reliable, and accurate triggering. This is especially beneficial in applications that require detecting sudden impulses and rapid changes, such as those detected by various types of light curtains, robotic arms, and automated safety systems. The D4NL-2EFG-B4 is a high quality snap action limit switch that features two metal contacts and an omron micro switch.

Application Fields

D4NL-2EFG-B4 snap action limit switches are typically used in applications that require detection of sudden shock and force impulses. The switch is primarily used in automated safety systems, such as those used in manufacturing facilities, but also in other industrial and commercial equipment, such as conveyor systems. Specifically, this type of switch is very effective for monitoring distances traveled, changes in force, position and speed adjustments. In some scenarios, the switch can also be used to trigger a safety shut-off or emergency stop.

Working Principle

The principle of the D4NL-2EFG-B4 snap action limit switch is to produce a mechanical impulse when a change in force or speed is detected, thus triggering a reaction. The switch includes two contact pads and a micro switch. The two pads are held in place by a spring, and when the pads are released, they generate an impulse which is transmitted by the micro switch, allowing the switch to activate. This allows the switch to detect a range of movements, from sudden shocks to gradual changes. As the switch is capable of reacting to extremely small changes, it is highly effective for a variety of uses.

The D4NL-2EFG-B4 snap action limit switch is a reliable and cost-effective way of helping facilitate automated systems, particularly when fast and accurate results are required. The switch is designed to detect a range of force, pressure, and speed changes with high precision and reliability, providing a valuable tool for any industrial or commercial application requiring rapid and precise control.
