Hongyan Technology EC28A C15H15P3 Hollow Shaft Incremental Encoder - 4096 P/R, 1024H

The EC28A encoder provides a standard incremental quadrature output, typically consisting of A and B channels (90 degrees out of phase) and a Z index pulse. The '1024H' bitstream designation refers to the signal format compatible with industrial counters and PLCs for precise pulse counting and direction detection.

This encoder features a 28mm through-hole (hollow shaft). You mount it by sliding it directly onto the motor or axle shaft. Secure it using the provided locking collar or set screws to clamp it concentrically, ensuring minimal radial runout for accurate signal generation. Always ensure the shaft is clean and within the specified diameter tolerance.

The encoder typically operates at 5V DC. Connect the Vcc and GND pins to the Arduino's 5V and GND. The A and B output channels connect to digital input pins configured with internal pull-up resistors. The Z index pin can be connected to another digital input if a reference pulse is required. Always consult the specific pinout for your C15H15P3 variant.

Yes. By counting the pulses from either the A or B channel over a fixed time interval, you can calculate rotational speed (RPM). For higher precision and direction detection, use both A and B channels in quadrature, which effectively quadruples the resolution for speed and position calculations.

'4096 P/R' (Pulses per Revolution) is the base mechanical resolution from the encoder disk. '1024H' likely refers to the electrical signal output per revolution after internal signal processing or a specific industry-standard counting mode. In many systems, one mechanical pulse generates multiple electrical edges, allowing for higher interpolation.
