SN04-N Inductive Proximity Sensor

What is the SN04-N proximity sensor? 

• Want to turn on a load when an object approaches? The SN04-N sensor may be your best choice. The SN04-N is a 4.0 mm detection range NPN NO output inductive proximity sensor designed to detect metal objects without touching them.

How to wire this proximity switch?

• This sensor has 3 wires, one wire is brown in color and needs to be connected to the positive pole of the DC power supply, and the other is blue wire and needs to be connected to the negative pole. The black line is the output. Since SN04-N is an NPN sensor, the load needs to be connected between this line and the positive electrode.

SN04-N inductive proximity sensor applications:

• Metal parts detection on production lines.
• Collision detection in robotics.
• Safety and security in interlock systems.
• Packaging industry.
• Position sensing of a machine element, such as a valve, gate, or elevator.
