Integration requirements are typically determined by the other components and setup of the application. Often these requirements cannot be changed and, therefore, are important to understand early in the process of selecting an inductive sensor. Inductive sensors are available for use with input supply voltages of AC, DC, or even AC/DC applications. Common output options available include Normally Closed (NC) and/or Normally Open (NO), NPN and/or PNP (DC), SCR (AC), MOSFET (AC), analog (DC) output, NAMUR, or IO-Link communication. Inductive sensors are available in threaded cylinder, smooth cylinder, and rectangular housings. The most common body style is threaded cylindrical in M8, M12, M18, and M30. These cylindrical housings are often offered in short and long bodies, referring to the length of the sensor. Some sensors are designed for flush mounting (also referred to as shielded), but others are designed for non-flush (also referred to as non-shielded) mounting, allowing additional sensitivity on the side of the sensing face. If more than one inductive sensor will be installed, research the operating instructions since the sensors can interfere with each other. There are inductive sensors available which can be programmed to operate without interference for this type of application. Typically, inductive sensors will only have two connection options to input power and output signal—quick disconnect (M8 or M12) or a cable with flying leads. The quick disconnect options are popular due to faster sensor replacement and easier connectivity troubleshooting. For larger inductive sensors, occasionally terminal connections are offered.
