Size: The operating distance refers to the size of the standard target.

Material: The sensor only detects different materials (ferrous metals, nonferrous metals, glass, wood, plastics, oil, water, and aqueous solutions).

Electric voltage: The voltage should be between 10 V.Switching element function: Check whether the specified switching element function is being observed: NPN or PNP? NC contact or NO contact?.Operating distance: The operating distance can be found in the product technical data and the product marking.The Target Is Not Detected, What Am I Doing Wrong?Ĭheck all settings, properties, and distances relating to the sensor and the target. The contact resistance and the risk of oxidation of the contact surface mean that a certain minimum current is necessary. Very small switching currents are also possible. As a result, a mechanical contact may supply multiple switching pulses per switch event.

The electronic output prevents contact bounce.Ĭontact bounce may occur at signal output. The contact transition resistances can change unpredictably. Mechanical contacts can become contaminated and worn over time. There are no moving contacts that can become contaminated or worn. The mechanical sequence takes time and sets narrow limits on the maximum switching frequency. Quick detection and thus short response and switching times, i.e., high switching frequencies are possible. Operation only possible with mechanical contact: objects to be measured can be manipulated or obstructed. Operation without touching the objects being measured.

Issues a mechanical signal, which is then transmitted electrically, hydraulically, pneumatically, or mechanically as required. The electrical output signals can undergo further processing directly in electronic circuits. Why Should I Use a Capacitive Sensor at All?
