Precautions

At power-on the internal circuit takes about 100 μs to stabilize. During this period any output signal would be unstable

and liable to change. Design the circuit so that no signal is output during this period.

The device when installed should be protected from interference by ambient light. The integrated phototransistor is

insensitive to light of 700 nm or less (e.g., fluorescent light), but is sensitive to light above 700 nm (e.g., incandescent

light). Detecting ambient light may cause the device to trigger a malfunction. Test and evaluate thoroughly any

end-equipment in which the device is used to ensure that no such interference will occur.

Take due care regarding the environment in which the device is to be installed. Oil or chemicals may cause the package

to melt or crack.

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.

Toshiba recommends attaching the device to the smoother side of the board.

Toshiba recommends testing the attachment strength beforehand by actually attaching a device to the board.

Do not apply solder to the pins of the device connector. Make sure that the connector is linked to the Mini CT connector

or equivalent connector.

When inserting or removing the Mini CT connector or equivalent connector, always grasp the connector and its cable

firmly and either plug the connector into or pull it out of the device connector straight and not at an angle. Inserting or

removing the Mini CT connector or equivalent connector at an angle may cause damage to both the connector of the

device and the Mini CT connector or equivalent connector, resulting in an unreliable connection.

The leadframe of the package and the resistance are exposed, as shown below. Design the housing and chassis of

end-equipment with particular care to ensure that no conductive material or object (such as a metal pin) drops on the

leads of the leadframe or on both ends of the resistance terminal to cause a short circuit between them.
