Connecting a proximity sensor to a PLC can be a daunting task at first glance. For one thing, there is no universal way to connect sensors. The process varies depending on the sensor and input module used in the configuration.
On quick visual inspection, a 2-wire NAMUR sensor looks the same as a standard 2-wire DC sensor. But do not confuse the wiring connections between these two types of sensors. On the inside, NAMUR sensors have different circuitry than standard 2-wire DC sensors and need special treatment.

Is it possible to meet every requirement of an application with a single solution? It all depends on the complexity of the application. Simple applications may only need simple digital-output sensors to detect the presence or absence of a target. But what about demanding applications that involve flaw detection, high-speed target inspection, precise positioning, profile comparison, or some combination of the above?

Ultrasonic sensors are non-contact devices used for object detection or level measurement. They operate on the principle of sound traveling through a medium, where a transducer emits a sound wave at a specific frequency. Based on the time it takes the reflected sound pulse to reach the transducer, the sensor’s internal logic determines if the object is within the nominal sensing range and generates an output signal.
