1.Attaching and Detaching Connectors
･
To attach a connector, hold the lever and connector unit between
your fingers and insert straight onto the pins of the solenoid valve
so that the lever’s pawl is pushed into the groove and locks.
･
To detach a connector, remove the pawl from the groove by pushing
the lever downward with your thumb, and pull the connector straight
out.
･
Connect the standard type in accordance with the +,- polarity
indication.(The non-polar type can be used with the connections
made either way.)
･
Since voltage specificaitons other than standard 24V and 12 VDC
do not have diodes for polarity protection, be careful not to make
errors in the polarity.
･
When wiring is done at the factory, positive (+) is red and negative
(-) is black.
2.Crimping connection of lead wire and socket
Strip 3.2 to 3.7mm of the lead wire end, insert each stripped wire into
a socket and climp contact it using special crimping tool. Be careful
that the outer insulation of the lead wires does not interfere with the
socket contact part.(Contact SMC for a special crimping tool.)
3.Connection/Disconnection of Socket with lead Wire
1)Connection
Insert a socket into the square hole (Indicated as +,-) of connector,
push the lead wire in and it by hanging the hook of socket to the
seat of connector.(Pushing-in can open the hook and lock it
automatically.) Then confirm the lock by lightly pulling on the lead
wire.
2)Disconnection
For pulling-out the socket from the connector, pull out the lead wire by
pushing the hook on the socket with a stick with a fine point (approx.
1mm ). If the socket is to be re-used, spread the hook to the outside.
How to Use Plug Connectors
Caution
Surge Voltage Suppressor

With power saving circuit
Power conumption is decreased by 1/4 by reducing the wattage
required to hold the valve in an energized state.
(Effective energizing time is over 62ms at 24 VDC)
Operating principle
With the above circuit, the current consumption when holding is
reduced to save energy. Please refer to the electric wave data below.
(In the case of SY **0T, the electric wave form of energy saving
type)
