These instructions cover installation, process connection, electrical connection and
calibration of the SOR
® Mini-Hermet explosion proof pressure switches.
The switching element is hermetically sealed in an explosion proof capsule
that is UL Listed and CSA Certified for hazardous locations Class I,
Groups A, B, C & D; Class II, Groups E, F & G; Divisions 1 & 2 and
SAA Approved for Ex s IIC T6 IP65 Class 1, Zone 1. When certain
options are ordered, the Pressure Switch may be ATEX Certified
EEx d IIC or UL Listed and CSA Certified Class I, Groups A, B, C & D;
Class II, Groups E, F & G; Divisions 1 & 2.
Static O-Ring Type (prefaced by 1, 5, 6, 9, 10 or 56)
Typical Model No. 6AG-EF3-N4-C1A
The static o-ring type pressure switch with optional wetted parts is
suitable for a wide variety of process applications. This type is not
recommended for high-pressure fluid power applications where
high shock pressure and high cycle rates are expected. Use SOR
pivot seal type for fluid power applications.
Pivot Seal Type (prefaced by 2 or 3)
Typical Model No. 3AH-EF45-P1-C1A
The pivot seal type pressure switch is generally suitable for fluid power hydraulic
applications where high shock pressures and high cycle rates are expected and where
only normally industrial clean hydraulic fluid is used. Use static o-ring type for other
process applications.
