When a cable other than one of the recommended cables above is used,
the voltage drop in the cable must be within 0.2 V for a +5 V power supply.
(Tip) Maximum cable length L can be found from the following formula:
L [m]x0.2 [V] n[line]B2BI [A]BR [Ω / m]
n : Number of power lines (number of +5V or +15V lines)
I : Current consumption of the detector
R : Resistance of a wire used for a power line
Detector Current consumption
M sensor (pulse generator) 0.035A
MZ sensor, BZ sensor (built–in sensor) 0.05A
Magnetic sensor (for orientation) 0.1A
Position coder 0.35A
High–resolution magnetic pulse coder 0.15A
High–resolution position coder 0.35A
Check the check board to confirm that the feedback signal waveform of
each detector satisfies the specifications.
