SKU CH-BKPE-4DVTS

A 10 psi diaphragm pressure switch with a 1NO contact, 1/8-27 MNPT port and 0.5 A at 240 V AC rating

  • TypeLight Switch
  • Actuates at 10 psi for precise pressure control
  • 1NO contact form simplifies wiring for single-circuit applications
  • Diaphragm actuation ensures reliable mechanical operation
  • Rated .5 A at 240 V AC for compatible voltage handling
  • 1/8-27 MNPT port fits standard plumbing connections

Honeywell 5000 Series 10 psi Pressure Switch

The Honeywell 5000 Series pressure switch is a diaphragm-actuated control calibrated to close at 10 psi. It carries a single normally-open contact rated for 15 A at 6 V DC, 8 A at 12 V DC, 4 A at 24 V DC, 1 A at 120 V AC and .5 A at 240 V AC. The port uses 1/8-27 MNPT threads for direct plumbing.

Suits low-pressure safety or pump control circuits

Installers needing a factory-set 10 psi actuation point with a 1NO contact will find this switch matches the requirement. The NEMA rating is not rated, so the device is not intended for wet, dusty or hazardous locations without a suitable enclosure. Buyers who need adjustable set-points, normally-closed contacts or a higher NEMA classification should select a different model.

Factory-set 10 psi actuation on a 1/8-27 MNPT port

The single specification that decides fit is the fixed 10 psi on-rise actuation combined with the 1/8-27 MNPT male pipe thread. Verify that the system pressure range of 8 to 13 psi and the contact ratings above match the circuit design before ordering.

Questions about this item

Should I choose the 10 psi setting or another pressure value for my application?

The switch is factory set at 10 psi with a differential range of 8 to 13 psi, so select it when your system must actuate within that window.

What does the 10 psi factory setting mean once the switch is installed?

It means the contacts will close when pressure rises to about 10 psi and open again when pressure falls back toward 8 psi, giving a repeatable on/off point.

How do the 1/8-27 MNPT port and contact ratings limit what I can connect?

The 1/8-27 MNPT port accepts matching pipe threads, while the contacts handle up to 1 A at 120 V AC, 0.5 A at 240 V AC, or 8 A at 12 V DC.
