■Others: Reference data
- Sensing distance characteristics and the effect of ambient temperature
The RGB output voltage value of this sensor varies depending on the ambient temperature. Shown
below is the reference data.
■Use of color sensors in practical applications
As mentioned above, the characteristic values listed in the product specifications specify a gray-colored
resin plate equivalent to general Munsell paper as the sensing object. Actual applications, however,
generally detect various objects other than that, and it is necessary to evaluate whether the sensor can
stably detect the target object in actual equipment over a long period of time. Specifically, it is necessary
to measure "Sensing distance - Output voltage" using actual objects to make sure that sufficient output
voltage values are obtained to discriminate color differences. As precautions in this case, the smaller the
output voltage value, the greater the influence of fluctuations due to noise and other effects. As a result, it
may be necessary to take measures to stabilize the output voltage value, such as increasing the average
number of times (this is especially true for subtle differences in color). In addition, it is ideal to evaluate as
many samples as possible, taking into account the individual variability of the sensor.
6 Usage (Circuit)
1. Connector
This sensor uses a connector for connection. Shown below is the model and terminal function of the
connector mounted on the sensor.
You must provide the harness. You also need to select the housing to be connected to the connector.
Shown below are the housing and contact listed in the manufacturer's catalog for the connector "SM05B-
SRSS-TB (J.S.T. Mfg. Co., Ltd.)" to be mounted on the sensor as reference information.
[Excerpt from the catalog of J.S.T. Mfg. Co., Ltd.]
Housing With protrusions: SHR-05V-S-B
Without protrusions: SHR-05V-S
Contact SSH-003T-P0.2-H
* You must determine the compatibility of the connector on the harness side and that on this sensor.
Note that the connector terminal (4) of B5WC-VB2322-1 is a blank one. Since it is not connected to the
internal circuit of the sensor, the operation of the sensor is not affected even if no wire is connected to the
terminal (4).
