Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...

Computer Conversions' Shaft-Tracker resolver-based encoder provides both incremental and true absolute position outputs with a resolution of 4096 counts/turn. A rugged, self-contained, resolver-based ...

Quadrature-output incremental optical shaft encoders are popular in high-performance, bidirectional rotation-sensing applications. Available with resolution options extending beyond 2000 ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.
