6.2 Digital output model
(4) Others, reference data
B5W-LB Light convergent reflective type sensor User’s manual (E592)
The influence to sensing distance by ambient temperature:
The sensing distance of B5W-LB will be changed by ambient temperature. The reference data is shown
below.
The average consumption current:
In the case that this sensor is operated with the recommended input pulse, the average current
consumption is approximately 32 mA.
The digital output model contains an LED driving circuit and a dedicated photo IC (with fixed threshold level).
As shown below, the output of the Main Circuit is routed through an NPN open collector transistor (Both,
internal to the sensor). Regarding the wiring, please refer to the data sheet or “Precautions for use” in the
product specification sheet.
The digital output model has a fixed threshold level internally. If there is any object/background which should
not be detected in the sensing area, the mechanical design should be modified to avoid detecting those objects.
Alternatively, please try to use the analog output model with proper threshold level setting.
