TLP1031A TOSHIBA Photointerrupter Infrared LED + Photo IC TLP1031A Domestic electrical appliances such as VTRs and CD players Office equipment such as photocopiers, printers and fax machines Trackballs Position detectors The TLP1031A is a high-withstanding-voltage photo-interrupter for digital output. The device combines a high-optical-output GaAs infrared LED with a high-sensitivity, high-gain Si photo-IC. The photo-IC, which supports a wide range of systems (3.3 V to 12 V), enables the device to consume less power than conventional devices. The device also features a narrow slit width and high resolution. · Compact package: Package height: 7.4 mm Depth: 4.5 mm · Designed for direct mounting on printed circuit boards (positioning pins included) · Gap: 2 mm · High resolution: Slit width of 0.15 mm · Digital output (open-collector, high-level output when no light is present) · Direct connection to logic IC · Power supply voltage: VCC = 2.7 V~15 V · Switching time: tpLH = 15 µs (max) · Detector impermeable to visible light · Package material: Polybutylene-terephthalate (UL94V-0, black) TOSHIBA ― Weight: 0.4 g (typ.)

Do not immerse the entire package in the cleaning solvent. Chemical residue on the LED emitter or the photodetector inside the photo-IC case may adversely affect the optical characteristics of the device and may drastically reduce the threshold input current. The case is made of polybutylene-terephthalate. Oil or chemicals may cause the package to melt or crack. Care must be taken in relation to the environment in which the device is to be installed. Mount the device on a level surface. Output fluctuates for 100 ms after power-on while the internal circuit stabilizes. To stabilize the power line, insert a bypass capacitor of up to 0.01 mF between VCC and GND, close to the device. The threshold input current increases over time due to current flowing in the infrared LED. The design of circuits which incorporate the device must take into account the change in threshold input current over time. The change in threshold input current is equal to the reciprocal of the change in LED infrared optical output.

If the material is of inferior quality, light from the LED may pass through the shutter, causing the device to malfunction. 3 2002-09-20 TLP1031A Package Dimensions Unit: mm Country of origin Slit width Anode Product number (TL omitted) Center of sensor ( ): reference value Weight: 0.4 g (typ.)
