MAGNETIC ENCODERS - CANOPEN ABSOLUTE MULTI TURN - THK4 RANGE
THK4 is a Ø36mm multiturn encoder with CANopen interface :
 Compact and robust design.
 Blind shaft Ø 6 mm version.
 Precision sealed bearings.
 High temperature performance –30°C to 70°C.
 Hall effect technology.
 Multiturn encoding based on magnetic pulse counter. No batteries used.
 CANopen interface, binary code.
 12 bits resolution = 4096 steps / turn.
 Number of turns : 13 bits = 8192 turns.
 Polarity inversions and surges protections.
 High integration SMD technology.
