C. 20–PIN INTERFACE CONNECTORS AND CABLES
Connector : PCR–E20FS (HONDA TSUSHIN KOGYO CO., LTD.)
Wires of 20 AWG or smaller can be soldered to the connector. However,
soldering many of these wires together lowers work efficiency because
the pitch of the soldering portion of the connector is too small to support
To increase work efficiency HIROSE ELECTRIC has developed a new
connector. By thinning out the number of pins, its soldering portion has
a pitch equal to that of the conventional HONDA TSUSHIN MF
connectors. The FI40–2015S can be used for interfacing pulse coders and
manual pulse generators which require wires up to as 20 AWG thick for
connection with a +5V power source.
Cable wires generally need to be developed or ordered by the machine tool
builder for the Series 16/18.
FANUC has developed wires that specifically suit the interface connector
of the Series 16/18. They are listed in the table below, for your
convenience when ordering from the manufacturer.

For the pulse coder, scale, and manual pulse generator, each of which has a +5–V power
supply, wires need to be selected taking into consideration the supply voltage drop caused by
the resistance of the cable.
A66L–0001–0371 is larger in diameter than conventional cable, therefore, use it with the
following connector as a pair:
FI40A–20S (connector) : Hirose
FI–20–CV5 (case) : Hirose
A66L–0001–0286 has been designed for use with a cable length of 20 mm or less. If the cable
length exceeds 20 m, use a cable with a lower resistance, such as A66L–0001–0157.
The number of manual pulse generators to be connected is assumed to be three. If only one
generator is connected, the cable can be extended to a maximum of 50 m by connecting wires
in parallel a cross–sectional area of 0.5 mm
for the power supply.
