Fc 51 Ir Sensor Datasheet Hot - !!link!!

If your sensor is currently running hot, disconnect the power immediately and follow these steps to safely troubleshoot the issue. Step 1: Verify the Power Source

| Parameter | Value | |-----------|-------| | Supply voltage | 3.3V – 12V (5V recommended) | | Current consumption | 20–50 mA (depends on LED and regulator) | | Sensing distance | 2cm – 30cm (depends on object reflectivity) | | Output type | Digital (TTL, active low) | | Comparator IC | LM393 | | Operating temp range | –25°C to +85°C | fc 51 ir sensor datasheet hot

The FC-51 splits its physical payload between emitting components, optical receiver blocks, logic comparators, and a simple 3-pin system header interface. System Interface Layout Power input line. Connect to the common power rail. GND: System reference ground. Connect directly to the If your sensor is currently running hot, disconnect

If your sensor is running hot to the touch, it is likely due to one of the following "hot" issues: Connect to the common power rail

: IR transmitter (LED), IR receiver (phototransistor), and an LM393 comparator chip. Why It Might Be "Hot" (Thermal Behavior)
