Description

This photoelectric incremental rotary encoder generates quadrature (A/B) and index (Z) pulse trains in response to shaft rotation, enabling precise measurement of angular displacement, speed, and acceleration. The optical sensing mechanism, based on a grating disc and optocoupler, provides high reliability and long operational life with minimal mechanical wear.

Designed for industrial automation, the encoder features an IP54 protection rating against dust and water ingress, a stainless steel shaft for durability, and a shielded 2-meter cable with a waterproof interface. The NPN open-collector output circuit requires external pull-up resistors for proper signal conditioning and protection against electrical interference, ensuring stable data transmission to counters, tachometers, and programmable logic controllers (PLCs).

Key Features

  • High-resolution optical encoder with 1000 pulses per revolution (PPR) and 4000 counts per revolution (CPR).
  • IP54-rated enclosure and waterproof cable gland for protection against dust and water splashes.
  • NPN open-collector output (A, B, Z phases) compatible with 5-24V DC industrial control systems.
  • Stainless steel solid shaft ensures high torsional strength and corrosion resistance.
  • Maximum rotational speed of 5000 RPM with a high response frequency up to 300 kHz.
  • Wide operating temperature range from -25°C to 85°C for use in varied environments.
  • Compact, lightweight design with a 2-meter shielded cable for flexible installation.
  • CE and RoHS compliant, meeting international electrical and environmental standards.

Applications

  • Precision motor speed and position feedback in industrial servo drives and CNC machinery.
  • Linear position measurement via measuring wheel or cable-pull mechanisms in conveyor systems.
  • Robotic joint angle sensing and closed-loop motion control for articulated arms and grippers.
  • Speed synchronization and registration control in labeling, printing, and converting equipment.
  • Angular displacement monitoring in medical analysis devices, plotters, and automated test stands.

Frequently Asked Questions

What is the purpose of the Z (Index) pulse on this encoder?

The Z channel provides a single index pulse per full shaft revolution, serving as an absolute reference point. This pulse is used for homing sequences, verifying total revolution counts, or synchronizing multi-axis systems by providing a known zero position within each rotation.

How do I interface this NPN open-collector output with my microcontroller or PLC?

The NPN open-collector outputs (A, B, Z) require external pull-up resistors to your logic voltage (e.g., 5V or 24V). Connect the encoder's output wires to your input pins through the pull-up resistors. This configuration protects the output transistors and ensures clean, noise-immune signal transitions for reliable counting.

What is the difference between PPR and CPR for this encoder?

PPR (Pulses Per Revolution) refers to the physical pulses generated per shaft turn (1000 here). CPR (Counts Per Revolution) is the quadrature count achieved by evaluating both the rising and falling edges of the A and B channels, yielding 4x the PPR (4000 CPR). This provides higher resolution for direction-sensitive position tracking.

Can this encoder be used for speed measurement, and what is its maximum frequency?

Yes, by measuring the pulse frequency from the A or B channel, you can calculate rotational speed. The encoder supports a maximum response frequency between 100 kHz and 300 kHz, allowing it to accurately track speeds up to its mechanical limit of 5000 RPM without signal loss.
