Absolute encoder WV36M/SSI

Metal housing with solid shaft

Magnetic, absolute multi-turn rotary encoder WV36M/SSI -batteryless, with SSI interface. Owing to its double ball bearing, small design and wear-free magnetic measurement method, the WV36M/SSI is also best suited for positioning jobs in mechanically demanding environments.

Profile WV36M/SSI:

  • Compact design (36.5mm diameter)
  • SSI interface
  • IP65 protection category
  • Multi-turn without battery
  • Double ball bearings
  • 13 bit multi-turn (8192 revolutions)
  • 12 bit single-turn (4096 steps)
