As a distance sensor with an adjustable sensing distance of up to 25 mm, the compact Sensorik disk sensor, 50 mm diameter, is suitable for scanning plastics, glass, ceramics, wood, etc.
This sensor's large active surface also enables it to be used as a fill level indicator, since it can detect liquids and granules through plastic or glass walls.
Typical applications here would include medical equipment, or use as an overfill safety feature in whirlpools.
Two mounting holes integrated into the housing, plus various cable arrangements, mean there are several different options available for attaching the plastic housing.
The sensor is protected to IP67. The control state is indicated by an LED visible from three sides, with rotary switches provided for user configuration of the starting position as NO/NC and PNP/NPN.
Attractive quantity discounts mean a favourable price/performance ratio for bulk buyers.
Applications
* Object detection: Detecting plastics, glass, ceramics, wood and all metals, etc.
* Fill level monitoring: Level control of liquids and granules like water, blood, cereals, coffee beans, etc. This will work with a glass, or plastic wall up to a maximum of 4 mm, depending on the material of the container wall.
Adjustment
The sensor is adjusted using a flush-mounted potentiometer.
Switchover
Rotary switches are provided at the back of the sensor for PNP/NPN function coding and NO/NC selection. The sensor is set by turning the relevant switch to the appropriate position for the switching function required.
As-delivered status
PNP, normally open (NO).
NC/NO coding
Turn the switch 270° anti-clockwise to switch over from NO to NC.
PNP/NPN-coding
Turn the switch 270° clockwise to switch over from PNP to NPN.
Signal evaluation
The SNG series (12.01-12.03) of sensor downstream devices is available for signal evaluation.
Depending on the application involved, you can choose between a power supply, a power supply with timer function, or a MinMax control unit.
