• HIGHLIGHTS: Comparator output, clean signal, good waveform, strong driving capability, more than 15mA.
• STRONG ANTI-INTERFERENCE:The transmissive optical sensor used consists of an infrared light emitting diode and a phototransistor. This both prevents interference from stray external light sources and by having the two components matched for a specific frequency of radiation, they are even more immune to undesired interference.
• EASY TO USE: The DO output interface can be directly connected to the IO port of the MCU to detect whether the sensor has a occlusion. If the motor code plate is used, the motor speed can be detected. The module DO can be connected to a relay to form a limit switch, or can be connected to the active buzzer module to form an alarm.
• EASY INSTALLATION: 3mm fixed bolt holes for easy installation.
• WIDELY APPLICATIONS: Widely used in motor speed detection, pulse counting, position limit, etc.
