Note: For more of connector characteristics, please contact the relevant connector manufacturer.
Precautions
q Keep the device away from external light. Although the photo-IC is of low optical sensitivity, the device may
malfunction if external light with a wavelength of 700 nm or more is allowed to impinge on it.
q Care must be taken in relation to the environment in which the device is to be installed. Oil or chemicals may
cause the package to melt or crack.
q When attaching the device to the metal board, always hold the body of the device. Do not hold it by the
connector. Ensure that the board is flat, and not warped or twisted. Attach the device to a metal board at room
temperature.
0 Toshiba recommends attaching the device to the smoother side of the board.
q Toshiba recommends testing the attachment strength beforehand by actually attaching a device to the board.
q Do not apply solder to the pins of the device's connector. Make sure that the connector is plugged into the Mini
CT connector or equivalent connector.
q When inserting or removing the Mini CT connector or equivalent connector, always grasp it and its cable firmly
and either plug it straight into or pull it straight out of the device's connector. If the Mini CT connector or
equivalent connector is inserted or removed at an angle, both the device's connector and the Mini CT connector
or equivalent connector may get damaged, resulting in an unreliable connection.
0 Conversion efficiency falls over time due to the current which flows in the infrared LED. When designing a
circuit, take into account this change in conversion efficiency over time. The ratio of fluctuation in conversion
efficiency to fluctuation in infrared LED optical output is 1:1.
