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.

Notes: 1) In the case of a model that is intended for use outside Japan, attach the unit switch plate corresponds to the set 
pressure unit.
  2) The product for use inside Japan can be set only to “MPa” or “kPa.”
2 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
3 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.

Sensor mounting bracket 
PPX-KL (Optional)
 ● The panel mounting bracket PPX-KHS (optional), as well as the front cover PPX-KCB 
(optional) are also available.
 ● For  mounting of the panel  mounting bracket, refer  to the Instruction Manual en-
closed with PPX-KHS.

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.
6 OUTPUT MODE AND OUTPUT OPERATION
 ● The EASY mode, hysteresis mode or window comparator mode can be selected as 
the output mode for comparative output 1 and comparative output 2.
Refer to  <Comparative output 1  /  2  output mode  setting> in  “

MENU  SET-
TING MODE” for details.
EASY mode
 ● ON / OFF of the comparative output is controlled in this mode.
