● Wiring
Each terminal should be careful not to exceed the rated. If install the cable, the user should be

and resin parts. And, after the wire, unnecessary force is not take care to apply to the
instrument by the wired cable.

4. Connection

 Wire connection
M12 connector with cable (available as option) should be inserted while aligning a notch
with that of a receptacle. Hand-tighten until the swivel nut is tightened.
Nut tightening torque 0.4 to 0.5 N・m.
Insufficient tightening of the nut may compromise water-proof characteristics.
Please sufficiently tighten the nut.
Wire connection of the connector is shown as below. Please turn on the power supply from
check the wire connection. Also, please perform the measurement taking into account the
actuation delay time
Do not wiring work, nor connect/disconnect connector while the power is turning on. There
is risk of electrical shock.
・1 ......... Power (+), COM(Select PNP open collector)
・2 ......... Open collector output 2
・3 ......... Power (-), COM(Select NPN open collector)
・4 ......... Open collector output 1
 Internal system
Output system is consists of NPN open collector output or PNP open collector output for
the comparator output. (It can be changed by ER40 IR COMMUNICATOR.)
Please refer to "1.Specification" with respect to output capacity of open collector.
wiring. The unit may have broken down if the comparator output is
different.
filled with a liquid. Because liquid is incompressible fluid, when the
pressure fitting is tightened a high pressure is generated thus causing a
damage to the unit. For existing pressure line or replacing the existing
unit, please drain the fluid within the pressure line to allow 15 to 20mm of
air when installing the unit.

because the diaphragm for detection is located at the tip of the
connection screw. Please be careful not to touch the diaphragm with a
hard solid.
