M8 connector Type
■Standard type (with polarity)
■Non- polar type
Solenoid valve side pin wiring diagram
• For the standard type, connect + to 1 and – to 3 for Type
W according to polarity, while + to 4 and – to 3 for Type
WA. • Please be careful not to reverse the polarity, since
a diode to prevent the reversed current is not provided
for DC voltages other than 24 and 12 VDC.
• The WA-type valve cannot be grounded.
<For AC>
(There is no "S" type because the generation of surge
voltage is prevented by a rectifier.)
Grommet, L/M plug Connector Type
DIN Terminal Type
Note) Surge voltage suppressor of varistor has residual
voltage corresponding to the protective element
and rated voltage ; therefore, protect the controller
side from the surge voltage. The residual voltage of
the diode is approximately 1V.

Specific Product Precautions 3
･Y type DIN connector conforming to DIN pitch 8mm
standard.
･ D type DIN connector with 9.4mm pitch between
terminals if not interchangeable.
･To distinguish from the D type DIN connector, "N" is listed
at the end of voltage symbol. (For connector parts
without lights, "N" is not indicated. Please refer to the
name plate to distinguish.)
･ Dimension are completely the same as D type DIN
connector.
･When exchanging the pilot valve assembly only. "V115-
□D" is interchangeable with "V115-□Y". Do not replace
V114(G,H,L,M,W) to V115 (DIN terminal), and vice
versa.
Caution
Connection
1. Loosen the holding screw and pull the connector out of
the solenoid valve terminal block.
2. After removing the holding screw, insert a flat head
screwdriver, etc. into the notch on the bottom of the
terminal block and pry it open, separating the terminal
block and the housing.
3. Loosen the terminal screws (slotted screws) on the
terminals block, insert the cores of the lead wires into
the terminals according to the connection method, and
fasten them securely with the terminal screws.
4. Secure the cord by fastening the ground nut.
Caution
When making connections, take note that using other than
the supported size (Ø3.5 to Ø7) heavy duty cord will not
satisfy IP65 (enclosure) standards. Also, be sure to
tighten the ground not and holding screw within their
specified torque ranges.
Caution
Changing the entry direction
After separating the terminal block and housing, the cord
entry can be changed by attaching the housing in the
desired direction (4 directions at 90°intervals)
*When equipped with a light, be careful not to damage the
light with the cord's lead wires.
Precautions
Plug in and pull out the connector vertically without tilting
to one side.
