HEDS-974x LPI Small Optical Encoder Modules

The HEDS-974x series is a high performance, low cost, optical incremental encoder module. When operated in conjunction with codestrip, this module detects linear position. The module consists of a lensed LED source and a detector IC enclosed in a small C-shaped plastic package. Due to a highly collimated light source and a unique photodetector array, the mod.

Features

• Small size

• No signal adjustment required
• Insensitive to radial and axial play
•
  –40°C to +85°C operating temperature
• High resolution version of the HEDS-970x
• Two-channel quadrature output
• TTL or 5.0 V CMOS compatible
• Single 5 V supply
• Wave solderable
• Integrated 2.5 KΩ pullup on outputs codestrip. These detectors are also spaced such that a light period on one pair of detectors corresponds to a dark period on the adjacent pair of detectors. The photodiode outputs are fed through the signal processi.
