Wiring
CRT1-MD16 (NPN)
CRT1-MD16-1 (PNP)
Note (1) The V1 and V2 terminals as well as the G1 and G2 terminals of the I/O
power supply are not connected internally. Supply power separately for
V1-G1 and V2-G2.
(2) When using an inductive load, such as a solenoid valve, either use a built-
in diode to absorb the counterelectromotive force or install an external di-
ode.
(3) Wire colors have been changed according to the revised JIS standards
for photoelectric and proximity sensors. The previous colors are shown in
parentheses.
