Avtron HS4 encoders are setting THE industry standard for incremental quadrature hollow shaft rotary encoders.  This versatile lineup fits the same mounting patterns on all motors and machines as competitor units, but that’s where the similarities end.  We've incorporated Avtron magnetic sensing technology to this affordable set of encoders!  This makes HS4 more resistant to dust, dirt, oil and other liquids that make ordinary optical encoders fail.

Our Wide-Gap technology provides for 10-20X larger air gap between sensor and rotor than ordinary optical encoder designs.  Consider the resistance to vibration when you compare our 0.060” air gap to the typical 0.004” clearance from the thin, often flexible, optical disk spinning at full motor speeds.  Our high-accuracy magnetic sensors provide high quality quadrature signals for precise velocity and position control with the durability of magnetic sensing technology.

Our magnetic HS4 encoders are setting a new standard for quality, durability, and performance. Select an Avtron HS4 today!
