Compact Pressure Switch Model KPH
Description
The KOBOLD KPH pressure switch is highly reliable, has a compact
design, and is ideal for OEM installations. Its long cycle life and rugged
mechanical design assure reliable service. The 8000 series is suitable
for low to medium pressure monitoring of air, gases, lubricating oil, light
fuels and many other types of compatible industrial media. The 8200
series is suitable for high pressure monitoring of lubricating oil, light
fuels and many other types of compatible industrial media. The KPH
snap-action switch comes standard with gold plated contacts which
have a mechanical reliability equal to that of a reed switch. If a reduced
contact life is acceptable for a specific application, the KPH surpasses
reed switches in its capacity to switch AC loads up to 5 amps.
