: v360 p/r -LRB- Single-phase 360 pulses / R, Two phase 4 frequency doubling to 1440 pulses -RRB-. vFor measuring angle, acceleration, length measurements and the move speed vFit for a variety of displacement measurement healthy control, measuring height of noncombatant body scale and so on. vSmall and ethical motive weight, comfy to install, cost-efficient features. Connection : chromatic colour = A phase, wild blue yonder = B phase, Red = Vcc power +, someone = power - Notice : AB 2phase output must not be directly with VCC, otherwise, will burn the output triode.
