D4NL-4BFH-B

Snap Action, Limit Switches

Snap action, limit switches are widely used in modern electrical and electronic circuits for many different applications. In particular, the D4NL-4BFH-B model limit switch is designed to open and close contacts when actuated mechanically. This switch is available in a variety of different actuator styles and contact configurations to suit specific requirements.

Application Field

The D4NL-4BFH-B limit switch can be used for a range of applications, including positioning systems, door activation, safety interlocking, detecting the presence or absence of object, and controlling the speed of automated machinery. The switch can also be used in harsh industrial environments, such as those with impacts, vibrations, or strong dust particles.

Working Principle

When the plunger of the D4NL-4BFH-B limit switch is pressed, a mechanism inside the switch body actuates the special magnetic strip. The magnetic strip then makes contact with either the normally open or normally closed contacts, depending upon the type of switch configuration and desired action. This action opens or closes the contacts, thus controlling the electrical or electronic circuits connected to the switch.

Additionally, the snap action of the limit switch ensures quick and reliable operation and prevents accidental or undesired operation due to over-travel, shock, or vibration. This prevents the switch from being undesirably actuated and provides a high degree of operational safety and reliability in the field.

Conclusion

The D4NL-4BFH-B snap action limit switch is a highly reliable and versatile device for a range of electrical and electronic application. The switch’s unique design, robust construction, and quick actuation provide it with high performance and reliability. Therefore, the device is an ideal choice for many different applications and environments, including those that require an additional degree of protection from impacts and vibrations.
