product description
description:

Not all materials are subject to 10MM detection limits.

Three factors that affect sensor function:

Material density Most plastic materials can not be detected by capacitive proximity sensors at the proper distance, sometimes because of the density too low, sometimes because the plastic is too thin, for example, if an empty 1 mm thick plastic bottle is detected, the detection distance may be Less than 2mm, if filled with water bottles, the detection distance may exceed 5mm.
2. Sensitivity, when the sensor can not work, the sensor has a sensitivity adjustment screw on the back, you can use a flat-blade screwdriver clockwise to increase the sensitivity of the sensor
Load current. High output current may cause product malfunction. Inductive loads, such as motors that draw large currents at start-up, are not allowed to connect directly to this sensor because this sensor can only provide 300mA of current to the load and you can use this sensor to provide a low-level signal to PLCs that require very little current, Or you can control small relays that require coil currents less than 100mA.
