NPN 3 Wires Inductive Proximity Sensor Switch

• The cover is made of thermoplastic and brass alloy.
• The sensor built in over-load protection, short-circuit protection, reverse-connection protection and surge absorbing circuits.
• Multiple connection options, flexible and convenient installation.
• Protection degree can reach IP67, water-proof, oil-proof and dust-proof.
• LED indicates work condition.
• Widely used in water level and liquid lever detection, industrial automatic production line detection, safety detection, position detection and alarm application detection, etc.

These switches are connected to the load and power supply separately; The polarity, short circuit, overload protection function and the residual current can be ignored.

The load must be connected in series in the sensor, in the closed circuit. The switching element has a smaller voltage drop.

Non shielded proximity switches can achieve maximum operating distance(with the diameter of the relevant); but in order to prevent the switch around the metal impact on the switch, the sensor head must be in a certain gap with the surrounding metal(Figure 1).

Due to the special shielding effect inside the shield, the radial magnetic field of the side is reduced, and the induction distance is about 60% of the non shield type, because it can be flush mounted in the metal(Figure 2).

The magnetic sensor is not affected by the conditions of installation, as long as the material around the material is not magnetized.

In order to prevent mutual interference, we must keep the minimum distance between each other(Figure 3).
