Hongyan Technology EC25-20P Hollow Shaft Incremental Encoder - 5-Pin Plug-in

The EC25-20P is an incremental encoder that outputs standard quadrature signals (A and B channels) for determining direction and counting pulses, plus an index (Z) signal that provides a reference pulse once per revolution. The specific electrical interface (open collector or line driver) should be verified against the datasheet for your specific model.

Typical supply voltages for this encoder series are 5V DC or 12-24V DC. The 5-pin vertical plug-in connector commonly uses the following pinout: Pin 1: Vcc (Supply+), Pin 2: 0V/GND, Pin 3: A Channel Output, Pin 4: B Channel Output, Pin 5: Z Index Output. Always consult the official manufacturer documentation for the exact pin configuration before connecting.

Yes, hollow shaft encoders like the EC25-20P are designed for direct mounting, which minimizes mechanical play and allows for high rotational speeds. A typical maximum operating speed is around 5000 RPM. Ensure the mounting is secure and the shaft diameter matches the encoder's bore size to prevent vibration and ensure signal integrity at high speeds.

The EC25-20P features a robust housing, but its specific IP (Ingress Protection) rating should be confirmed for your application. Encoders in this series often have ratings like IP50 or IP64, protecting against dust and light splashing. For environments with heavy washdown, moisture, or oil mist, an encoder with a higher IP rating (e.g., IP67) would be recommended.
