The TLP1037A is a high-withstanding-voltage photo-interrupter for digital output. The device combines a high-optical-output Ga As 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. The device is housed in a deep-slot package.

Frequently Asked Questions
What power supply voltage range does the sensor support?
The device supports a wide operating voltage range between 2.7 V to 15 V CC.
Can this detector be used in low-power systems?
Yes, its design allows it to consume less power than conventional devices and the photo-IC supports 3.3 V to 12 V systems.
What precautions should I take when soldering or cleaning the package?
Only clean the soldered lead parts; do not immerse the entire package in the cleaning solvent, as residue can damage optical performance.
Is there a delay before the output signal stabilizes after power-on?
Yes, the output fluctuates for 100 µs after power-on while the internal circuit is stabilizing.
