ACS712T 5A Range Current Sensor

Linear Hall-Effect Transducer Core: Powered by the Allegro ACS712TELC-05B IC, delivering precise analog voltage output proportional to AC or DC current streams.

Galvanic Isolation Protection: Features 2.1 kVRMS voltage isolation between the primary copper conductor path and low-voltage control circuitry for high safety.

Low-Current $\pm 5A Sensing Range: Optimized specifically for low-current applications up to ± 5A, centered around a V_CC/2 zero-current output offset voltage (2.5V).

High Analog Sensitivity Scale: Factory calibrated to 185 mV/A sensitivity, delivering high resolution for precise micro-load and low-current monitoring.

Heavy-Duty Screw Terminal Block: Outfitted with a 2-pin screw terminal block for secure, low-resistance connection to target power lines.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with surface-mount ACS712 IC, green terminal block, and tinned header pins.

Technical Specifications:

Operating Supply Voltage (V_CC): 5.0 V DC.

Current Measurement Range: ±5A AC or DC.

Sensitivity Rating: 185 mV/A.

Color: Blue PCB with Green Terminal Block and Silver Pins.

Usage Advice: Connect 5V VCC, GND, and OUT to your microcontroller ADC; wire the load line through the screw terminal block pads (IP+ / IP-).

Maintenance: Keep terminal block screws properly tightened; handle with ESD protection and keep PCB surfaces free from dust, moisture, and flux residue.

Essential Low-Current Precision Module: Position as an ideal Hall-effect sensor for low-power robotics, light DC motor profiling, small solar panel diagnostics, and high-resolution current logging.

Highlight High Sensitivity (185 mV/A): Emphasize how 185 mV/A sensitivity yields higher signal resolution than 20A or 30A variants when sampling currents under 5A.

Recommended Cross-Sell Add-ons: Pair with ACS712T 20A Range Current Sensor, ACS712T 30A Range Current Sensor, INA219 Bi-directional DC Current Power Supply, and ESD antistatic mat 50x40CM PCB Welding Mat.
