Dietz 5-30 PSI Medium Pressure Switch (200P-2-4M-C-HC)
This Dietz Medium Pressure Switch is an essential electromechanical component for safety and control logic within the Tommy RO System (Reverse Osmosis). It is commonly assigned to the PRS4 monitoring point, where it monitors pressure within the crucial 5 to 30 PSI range. This pressure band is vital for tasks such as confirming adequate feed water supply or monitoring inter-stage pump pressures.
The switch is housed in a compact, rugged Brass body for excellent resistance to corrosion from both air and water applications. It features a Nitrile diaphragm and can safely withstand a maximum overpressure of 350 PSI. The SPDT (Single Pole, Double Throw) snap-action switch allows for versatile wiring options, rated up to 5 Amps at 12/24 VDC or 125 VAC. Its mechanical life is rated for over one million cycles, ensuring exceptional longevity.
Installation is straightforward with a 1/4" NPT Male pressure port and a standard DIN 43650 A connector for the electrical hookup. The IP 65 rating provides a high level of protection against dust and water jets, making it perfectly suited for the backroom environment.
