PEC Rotary Encoders

Bourns Pro Audio PEC Rotary Encoders feature a compact design, long life, high reliability, and low cost compared to optical type encoders. Available in a wide variety of configurations. The Bourns Pro Audio PEC Series Rotary Encoders are incremental encoders with a 2-bit gray code output, 3Ω max closed circuit resistance, and a contact rating of 1mA @ 5VDC. Also available is the PES12 series, a 12mm incremental shaftless encoder with detent option.
