Snap action, limit switches are commonly used in industrial environments for controlling devices, signals and power. The D4NH-4FBC is a highly reliable and rugged inductive limit switch designed for extreme environments. It has various application fields and is suitable for harsh and hazardous areas such as dust, water and oil.

In many application fields, the D4NH-4FBC can be used as level signalling, position control and indication, or as a control switch in hazardous areas. The working principle of this popular switch is based on electromagnetic induction. It has two main parts: the magnetic head and the switch body.

The magnetic head is a permanent magnet mounted to a moving member. This generating a magnetic field that extends to the switch body. When the moving member approaches the switch body, the magnetic flux saturates an inductor. This changes the flux and produces an alternating current in the inductor which is then transmitted to the supply circuit in order to activate the switch.

The D4NH-4FBC has to be wired in series with the circuit it controls and the supply must be connected to a live circuit. The switch contacts are normally open and close when the supply voltage is removed. The contacts remain closed until the magnetic field is again induced and the switch contacts open. This type of switch is used in applications where a delayed response is required as the contacts will remain closed until the power supply is interrupted.

The D4NH-4FBC is widely used in hazardous areas in order to increase safety. The switch can be used to detect changes in process conditions, the presence of liquids, gases and other dangerous materials. It can also be used for indicating the presence of sparks, smoke, heat or high temperatures. This makes it a reliable and safe solution for monitoring and controlling processes in hazardous environments.

The D4NH-4FBC is a highly reliable and durable switch which is suitable for extreme environments due to its robust construction and low maintenance need. Its basic working principle makes it easy to install and use and its wide range of application fields makes it a versatile solution for many industrial applications.
