Quadrature channels with complementary outputs and a zero-index channel for directional position feedback.

845H-SJDZ24FWY2C

A 1024 PPR square-flange encoder that converts shaft rotation into differential quadrature pulses for position, speed and direction control. The configuration uses an 8–24 V DC supply, a 3/8-inch shaft with flat and a radial connector.

Pulses per revolution with a 210 kHz data-channel response and 125 kHz index response.

The machine shaft turns the encoder through a correctly aligned coupling.

The code disc produces 1024 pulse cycles per revolution.

Differential quadrature carries position, direction and index.

The controller calculates position, direction and rotational speed.

1024 PPR Is Only One Part of the Match

An encoder with the same resolution can still be incompatible. Confirm mechanical mounting, shaft geometry, supply voltage, output driver, pinout, connector direction and index behavior.

Worldwide coverage for supplied items.

Contact us within seven days, keep the item in original condition and explain the concern. Return or replacement follows inspection; buyer covers shipping costs.

Not automatically. Match flange, shaft, connector orientation, supply, output driver, pinout and index behavior.

Use a high-speed differential receiver compatible with the supply and A, A-complement, B, B-complement, Z and Z-complement signals.

Calculate pulse frequency from RPM and 1024 PPR, keep it below 210 kHz and the input limit, and remain below the mechanical speed ceiling.

Avoid shaft misalignment, excessive axial or radial load and rigid coupling stress; support the cable so it does not pull on the radial connector.

Confirm supply polarity, channel sequence, direction sign, zero index, counts per revolution, shield continuity, noise immunity and stable counting throughout the machine speed range.
