Failure to select the correct resistor value can lead to the sensor not operating or being damaged.
Note: All OL T... devices are supplied with lead wires. The wire lengths are 200 mm -0, +30 mm measured
from the back of the housing. Wire diameters are 0.51 1 mm (AWG 24) for all OLT01... devices and
0.812 mm (AWG 20) for all OL T25/50... devices.
