CIRCUIT DIAGRAMS
In order to suit any application, these sensors have been designed with various output circuit configurations.
CAUTION: Take care when connecting loads.
The minimum load impedance should not exceed Vs/max output current.
Note: Shorting the output to Vs or 0V will result in irreparable damage to the sensor.
ORDER INFORMATION
Generate your specific part number using the convention shown opposite. Use only those letters and numbers that
correspond to the sensor and output options you require — omit those you do not.

CAUTION
Do not exceed maximum ratings and ensure sensor(s) are operated in
accordance with their requirements.
Carefully follow all wiring instructions. Incorrect wiring can cause
permanent damage to the device.
SST Sensing Ltd recommend using alcohol based cleaning agents.
Do NOT use chlorinated solvents such as tricholerthane as these are
likely to attack the sensor material.
Failure to comply with these instructions may result in product
damage.
