MAGNETIC ENCODERS - SSIR ABSOLUTE MULTI TURN - THM4 RANGE
THM4 is a Ø36mm multiturn encoder with SSI interface :
 Compact and robust design.
 Solid 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.
 SSI interface, GRAY code.
 12 bits resolution = 4096 steps / turn (max 14 bits).
 Number of turns : 13 bits = 8192 turns.
 Polarity inversions and surges protections.
 High integration SMD technology.
