Fc 51 Ir Sensor Datasheet Jun 2026

Approximately 23mA at 3.3V and 43mA at 5.0V . Performance Review Pros

The is a popular, cost-effective module used widely in robotics for obstacle avoidance and proximity detection. Using a simple infrared "reflection" principle, it identifies objects by bouncing IR light off surfaces and measuring the return signal. FC-51 Key Technical Specifications Specification Operating Voltage 3.0V – 6.0V DC Detection Range 2cm – 30cm (Adjustable via onboard potentiometer) Detection Angle Current Consumption ~23 mA at 3.3V; ~43 mA at 5.0V Output Type Digital signal (0 or 1) Onboard IC LM393 Dual Comparator Pinout Configuration Fc 51 Ir Sensor Datasheet

Based on your request, here is the technical information and specification summary for the . Approximately 23mA at 3

When an object enters the detection range, the light reflects back to the photodiode. This directly changes the detection distance

The blue potentiometer on the FC-51 adjusts the reference voltage for the LM393 comparator. This directly changes the detection distance.

. It consists of an IR transmitter and receiver pair, using a comparator circuit (LM393) to provide a simple digital output Ktechnics Systems Technical Specifications Operating Voltage: 3.0V to 6.0V DC Current Consumption: approximately at 3.3V and Detection Range: 2 cm to 30 cm (adjustable via onboard potentiometer) Art of Circuits Detection Angle: Output Signal: Digital (High = No Obstacle, Low = Obstacle Detected) Art of Circuits Dimensions: Approximately 43mm x 16mm x 7mm Радіокомпоненти Pinout & Hardware Features
