D4GL-4HFA-A-NPT Application Field and Working Principle

Snap action, limit switches have been widely used in many industries and applications where precise control of electronic, mechanical and hydraulic systems is required. The D4GL-4HFA-A-NPT limit switch from Omron is one such device which offers superior performance and reliability in these applications. It is a subminiature size limit switch which offers a high degree of protection from dust and water and is ideal for use in confined spaces.The D4GL-4HFA-A-NPT limit switch has two main components; the actuator and the contact. The actuator is a plunger type which is actuated by the motion of a mechanism such as a switch lever, cam, solenoid, etc. When the mechanism is moved to a predetermined point, the actuator pushes against the contact which in turn completes an electrical circuit, thus enabling the control of a system. The contact is available in different configurations depending on the application, such as snap-action, roller, and sliding contact.The D4GL-4HFA-A-NPT is a single pole, double throw (SPDT) snap action switch with a silver-plated brass contact. The contact construction is designed for flexibility, with a variety of electrical connections, such as push-in, soldering pin, plug-in, and terminal block. It is designed to operate at up to 16 amps, 125 VAC and 28 VDC. The contact rating is 0.5 amp, 250 VAC/30 VDC, making it suitable for low-voltage applications.The operation of the D4GL-4HFA-A-NPT switch is quite simple; when the mechanism connected to the plunger are moved to a predetermined point, the plunger pushes against the contact which in turn completes an electrical circuit. The adjustable screw on the side of the switch can be used to adjust the pressure needed to actuate the contact, thus allowing for precise control of the switch\'s operation.The D4GL-4HFA-A-NPT limit switch from Omron can be used in a variety of applications, such as automotive, industrial, and medical applications. It offers reliable and precise operation in a wide range of environments and is easy to install. The device\'s high degree of protection from dust and water makes it suitable for use in confined spaces, making it a great choice for those looking for a versatile and reliable switch.
