Features
Product Introduction
TP-12 optical scanning probe can sense both light and IR(Infrared) light pulses emitted by LED, and then convert them to electric pulses. TP-12 is designed with two power supply modes, one is powered by +5V which is supplied by outer power source, and LED indicator on top of probe is enabled in this mode. The other power source is +3.3V which is suitable for battery power system on very low consumption. LED indicator on top of probe is disabled in this mode.
Strong Compatibility
Detects lights of different colors and wavelengths, converts light pulses to electric pulses. Has two power supply modes and various connectors.
Fixed Method
Supports multiple fixing methods like magnets, double - sided tapes, etc. Double - sided tape is popular for convenience and protection.
High Sensitivity
Supports min 200μs pulse width, max 5kHz frequency. Senses multiple colors of light, resists interference, usable indoors and outdoors.
Excellent Performance in Harsh Environment
Made of 100% PC material, works well in summer sun or winter blizzards. Has top - level enclosure, strong magnet, and durable cable.
