Hengstler AC58 Series 0574329 Absolute Optical Rotary Encoder - 0 Detents, Horizontal, IP64/IP65, Binary Output

An absolute encoder, like the Hengstler 0574329, provides a unique digital code (binary output) for each shaft position, giving the exact angle immediately upon power-up without needing a reference point. An incremental encoder only outputs pulses relative to movement and requires a homing routine to establish a zero position after each power cycle.

The encoder outputs a parallel binary code. You must connect the power supply (7-30 VDC) and ground pins, along with the multiple data lines representing the bit positions of the binary code. The specific pinout and number of bits (resolution) should be confirmed from the official Hengstler AC58 series datasheet for integration with PLC digital input modules or dedicated encoder interfaces.

Yes, its IP64 and IP65 ratings make it suitable for many industrial environments. IP64 protects against dust ingress and water splashing from any direction, while IP65 protects against low-pressure water jets (6.3mm nozzle). It is suitable for indoor industrial settings with dust or occasional washdown, but not for prolonged submersion (IP67/IP68).

The provided data specifies it as an absolute encoder with binary output but does not state the bit count (e.g., 8-bit, 10-bit, 12-bit) which defines its resolution. The resolution determines the number of unique positions per revolution. For exact resolution, please consult the official Hengstler datasheet for the AC58 series, model 0574329.
