•
Set the ON-pressure by the pressure setting trimmer. Turning
clockwise can set the high pressure/high vacuum pressure.
•
In the event of setting, use a flat head screwdriver suited for the
groove of a trimmer, and rotate it lightly with a fingertip.
•
Switches with variable hysteresis can be adjusted by means of
the HYS potentiometer in the range 1 to 10% of the setting
pressure range.
•
Readjust the ON-pressure setting when the hysteresis setting
trimmer was changed after setting the ON pressure.

Regarding the pressure setting
•
Set the possible min. pressure for adsorption confirmation. If
setting the pressure lower than that, switch becomes ON in
case that adsorption is not completely done. If setting the pres-
sure higher than that, switch does not become ON even though
it may absorb workpieces.
Observe the following precautions for setting the vacuum pres-
sure:
Use your fingertips to gently turn the screwdriver.
Do not use a screwdriver with a large grip or with a tip that does
not fit into the trimmer groove because this could strip the groove.
Hysteresis
Hysteresis is the pressure difference between the ON and the
OFF pressure of the output signal. The set pressure is the pres-
sure selected to switch from OFF to ON condition.

How to Use Connector
1. Attaching and detaching connectors
•
When assembling the connector to the switch housing, push
the connector straight onto the pins until the lever locks into the
housing slot.
•
When removing the connector from the switch housing, push
the lever down to unlock it from the slot and then withdraw the
connector straight off of the pin.

2. Crimping of lead wires and sockets
Strip 3.2 to 3.7 mm at the end of the lead wires, insert the ends
of the core wires evenly into the sockets, and then crimp with a
crimping tool. When this is done, take care that the coverings of
the lead wires do not enter the core wire crimping area.

3.Attaching and detaching lead wires with sockets
•
Attaching
Insert the sockets into the square holes of the connector (with
+, 1, 2, – indication), and continue to push the sockets all the
way in until they lock by hooking into the seats in the connector.
(When they are pushed in their hooks open and they are locked
automatically.) Then confirm that they are locked by pulling
lightly on the lead wires.
•
Detaching
To detach a socket from a connector, pull out the lead wire
while pressing the socket’s hook with a stick having a thin tip
(about 1 mm). If the socket will be used again, first spread the
hook outward.
