Pressure Switch for Air and Liquid Systems

The IFM PN4223 is a digital pressure sensor designed to monitor and control pressure in industrial automation circuits. It operates on a 90 to 250V AC supply at 45 to 65 Hz and provides a SPST Triac output rated for 2.5A at 20 degrees C. The stainless steel housing and wetted parts resist corrosion in demanding environments.

IP65 Protection and Temperature Tolerance

The switch carries an IP65 rating, shielding internal electronics from dust and water jets during normal operation. It functions reliably across an ambient range of 13 to 176 degrees F. The 1/2 inch UNF 5-pin connector ensures a secure electrical link without exposed wiring.

Adjustable 0 to 363 psi Range

The set points adjust from 4 to 363 psi on and 2 to 362 psi off, covering a broad span for pneumatic or hydraulic lines. A 1/4 inch FNPT process connection threads directly into standard ports. The sensor withstands a burst pressure of 5,075 psi for safety margin. Buyers who need a different thread size or a voltage outside 90 to 250V AC must select another model.

Questions about this item

How do I wire the 5-pin 1/2 in UNF connector to my 90-250V AC supply?

Connect the supply across the two triac output pins; the remaining pins are unused for this SPST switch. Torque the connector to the rated spec so the IP65 seal seats.

What part will need replacement first in a system cycling at 363 psi?

The stainless-steel wetted parts and triac output are rated for the full range; the 5,075 psi burst margin means the sensor itself rarely fails before seals or external piping.

At what ambient temperature does the 2.5 A output rating start to drop?

The 2.5 A rating is specified at 20 °C; above that temperature the triac's thermal derating reduces the allowable load current.
