Broadcom 5V dc 1024 ppr Pulse Optical Encoder with a 8 mm Hollow Shaft, Standard, External, 5 x 0.025 Inch Square Pin on

Broadcom HEDS-55xx Series Optical Encoder, 1024ppr Pulses Per Revolution, 5V DC Supply Voltage - HEDS-5540#A11

This optical encoder converts rotational motion into digital signals for motion control and position feedback in electromechanical systems. It operates from a 5V DC supply and provides quadrature outputs with an additional index Pulse to enable precise angular measurement and reference marking. The device is designed for external mounting and accommodates hollow-shaft installations, making it suitable for integration where axial coupling is required.

Features and Benefits:

• 1024ppr resolution delivers fine incremental position information
  30000r/min max speed supports high-speed rotational applications
  5mA current rating minimises supply loading during operation
  5V quadrature output with index Pulse enables accurate phase and reference detection
  Square pin termination on 0.1in centres simplifies PCB or socket connection

Applications

• Suitable for closed-loop motor speed control systems
  Ideal for rotary Axis position feedback in automation
  Used with hollow shafts requiring direct shaft insertion
  Can be used for encoder retrofit where external mounting is available
  Appropriate for systems requiring RoHS-compliant components

What shaft Interface does it require?

It fits an 8mm hollow shaft enabling direct shaft insertion for Compact coupling.

How is the unit mounted to equipment?

It uses external mounting with 0.25mm hole diameter for securing to a host structure.

What form of electrical termination is provided?

Electrical connection is via five 0.025in square pins on 0.1in pitch to mate with standard headers.

Does it include an index signal for homing routines?

Yes, it provides an index Pulse in addition to two quadrature channels for reference positioning.
