3.3 VOLT COMPACT OPTICAL COMMUTATION ENCODER
Description
RENCO ENCODERS INC. of Goleta, CA, introduces a 3.3 Volt feature for the RCML15. The RCML15 is compact optical encoder that provides signals for brushless motor commutation as well as incremental position feedback in a low profile (.350” height) optical encoder. A custom LED and CMOS sensor arrangement reduces cost while improving performance and reliability of the encoder package. Encoder frequency response reaches 500 KHz. Supply voltage is +3.3 VDC +/- 10% Max Ripple, 40mv pk-pk. The RCML15 features RENCO’s patented slide/gap mechanism for ease of installation and maximum performance, and ± 20° rotation of the encoder to align the commutation signals with the motor poles. The RCML15 is available in a wide selection of resolutions up to 4096 and provides commutation for 4, 6, 8 and 10 pole brushless motors. The RCML15 meets all requirements in NEMA’s ICS-16 standard.
