NO. OF INPUT P/R Can be specified from 1 to 120 pulse.
Pulses/rev. :
INPUT IMPEDANCE Approx.50k
MIN. PULSE WIDTH Approx.50μsec
DIMENSION OF TARGET
(Model VK,RD,FK)
Note) To detect a projection (gear), provide surface A of the projection with a concentric curve.
Do not make it flat.
A= mm

NO. OF INPUT PULSE 1 to 120 pulse
TRIGGER MODE AUTO, MANUAL (selectable)
In case of auto trigger mode, input pulse duty ratio should be between
10 and 90% and input pulse frequency should be 1Hz and over.
It depends on the target.
