1. INTRODUCTION
The NIMET BC capacitive proximity sensors are for industrial automation tasks for non-contact detection of metallic and non-
metallic objects (water, plastic, stone, wood, etc.). The NIMET BC capacitive proximity sensors operate like an open capacitor.
The dielectric of the capacitor is the air. If there is an object with a significantly different dielectric constant in the sensing area,
the switch will change state. The material-dependent sensitivity can be set with the potentiometer. Devices with a DC power
supply have short-circuit protected PNP or NPN transistor outputs. Devices with an AC power supply have a thyristor-driven
output. Furthermore, there is a LED and a potentiometer on the backplate of the device. The LED shows the output state.

3. INSTALLATION
The device must be mounted with the two hex nuts provided with it so that the distance
between the device and the object to be detected is less than 70% of the sensing (switching)
distance of the given device.

Materials of sensing targets: Sensing distance may be different due to the electrical
characteristics of the target (conductivity, non-dielectric constant) and its physical
properties, like water absorption, size etc.
 High-frequency electric fields may cause malfunction, e. g., fields generated by
washing machines, etc.

Surrounding environment: water or oil on the surface of the sensing part may cause a
malfunction. If the sensing bottle is covered in oil etc., it may cause a malfunction.
Especially in the case of the 15 mm version (BCZ–16–), which is highly sensitive
to certain objects and water droplets.

Oil: Do not let the oil or other liquid flowed into the sensor or in the plastic case.

UTUAL INTERFERENCE
When several proximity sensors are mounted close to one another, the sensors may
malfunction due to mutual interference. Therefore, be sure to provide a minimum distance
between sensors as per the chart below.
Type
A [mm]
B [mm]
When sensors are mounted on a metallic panel, the sensors must be prevented from being
affected by any metallic objects except the target. Therefore, be sure to provide a minimum
distance as per the chart below.
