Pepperl+Fuchs’s ENI58IL incremental encoders first with blue emitter LEDs.
Pepperl+Fuchs introduced its ENI58IL rotary encoder with BlueBeam Technology, a short-wave blue emitter LED and receiver diodes that allow the encoder maintain pecision at rotational speeds up to 12,000 RPM. BlueBeam Technology allows a reduction in the tolerance of phase position A:B to well below 10%. Because the high-frequency sampling is less prone to interference, BlueBeam Technology also keeps signals stable when exposed to mechanical force like shock and vibration. Another advantage is the improved calibration of the code disk. The ENI58IL series also features interlocked bearings and EMC circuit protection. Various types of shafts (solid shaft, hollow shaft, recessed hollow shaft), flanges, (clamping, servo, square) and connections (axial and radial M23 or M12) are available.
