INSTRUCTION MANUAL
PARECT PRESSURE SWITCH
PPX series
Read this instruction manual carefully before using this product, particularly the section
describing safety.
Retain this instruction manual with the product for further consultation whenever necessary.
Precaution
● This product is designed for air / non-corrosive gas.
●
● Do not touch electric wiring connections (bare live parts): this will cause an electric shock.
During wiring, keep the power off. Also, do not touch these live parts with wet hands.
● A product intended for use in Japan conforms to the Japanese Measurement Act.
Do not use a product intended for use overseas in Japan.

PIPING
● When connecting a commercial coupler to the pres-
sure port, attach a 12mm spanner (14mm for 6G
type) to the pressure port’s hexagon section to fix
the port, and then tighten with a tightening torque of
9.8N·m or less (M5 female: 1N·m or less). The com-
mercial coupler or pressure port section will be dam-
aged if the tightening torque is excessive.
Wrap sealing tape around the coupler when connect-
ing to prevent leaks.
12mm spanner

MOUNTING
● The sensor mounting bracket
PPX-KL
is available as an option. When mounting the sensor
onto the sensor mounting bracket, etc., the tightening torque should be 0.5N·m or less.

Notes: 1) When the analogue current is output, the output load resistance should be 250Ω max.
2) Take care that when the analogue current is output, 5V or more voltage generates.
3) When using the analogue voltage output, be careful to the input impedance of the connected device.
Furthermore, note that if the cable is extended, the cable resistance will cause the voltage to drop.
