How Do You Wire An Inductive Proximity Switch?
Inductive proximity switches or sensors are used in industrial applications for sensing a metal part. When the metal part moves into close proximity of the sensor an internal switch is either opened or closed. The sensor is always labeled as N.O. (normally opened) or N.C. ( normally closed). This designation identifies the precondition of the switch and when actuated will reverse its condition. In other words, a normally open sensor when tripped will then close completing an electrical circuit. The same for a normally closed switch as it will open upon the sensor being triggered. A proximity switch is generally powered by a direct current source of low voltage in the range of 12 VDC to 36 VDC. Identify the type of proximity sensor or switch you need to install. Whether that condition is a NO or NC type. You should also confirm the power requirements of the sensor so you will not damage the power source or the device it is controlling. Install the proximity switch into the receiving hol
