The HEDS-9140 is a three channel optical incremental encoder module. When used with a codewheel, these low cost modules detect rotary position. Each module consists of a lensed LED source and a detector IC enclosed in a small plastic package. Due to a highly collimated light source and a unique photodetector array, these modules provide the same high performance found in the HEDS-9000/9100 two channel encoder family.

Features:

• Two channel quadrature output with index pulse
• Resolution up to 2000 CPR (Counts Per Revolution)
• Low cost
• Easy to mount
• No signal adjustment required
• Small size
• -40°C to 100°C operating temperature
• TTL compatible
• Single 5 V supply
