PreciSen™ — Zero-Calibration Absolute Encoder ASIC for Robot Joints
Zero Calibration.Instant Precision.
Patented 2D optical absolute encoders that eliminate factory calibration, shrug off contamination, and hold ≤ 0.01° native accuracy — on every joint and every axis.
≤ 0.01°
Native accuracy — without calibration
±2.5 mm
Mounting tolerance, plus ±5° tilt & twist
>90%
Worst-frame contamination absorbed — angle output unaffected
0
Factory calibration steps
Proven live
Deliberately misaligned. Still precise.
Zero calibration
Learns and cancels the mount's geometry in real time — immediate convergence in Advanced mode. Bolt it on, power it up.
Contamination immune
Above 90% of the optical field obstructed — angle output unaffected. Oil, dust and heavy markings are irrelevant.
Every joint, every axis
24-bit absolute sensing, ±2.5 mm mounting tolerance, SPI · I²C · BiSS · SSI — built for robot joints from cobot to humanoid.
