1 Pressure Range Code

Insert Pressure Range Code from Table 1, below.

2 Pressure Fitting¹

316 Stainless Steel -4MNS = 1/4"NPTM -4MGS = 1/4" BSPM (G type) -4FGS = 1/4" BSPF (G type) -6MSS = 9/16"-18 SAE Male

3 Circuit

-A=SPST/N.O.

-B = SPST/N.C.

-C = SPDT -AA = DPST/N.O.²-BB = DPST/N.C.²-CC = DPDT²

4 Electrical Termination

-FLXX=Flying Leads³

5 Options

-V=Viton® Diaphragm -N = Neoprene Diaphragm -E=EPDM Diaphragm -G = Gold Contacts

(for loads less than 12 mA @ 12 VDC) -RD = Reduced Differential (25% reduction typical) -OXY=Oxygen Cleaned⁶-R=Restrictor (low damping coefficient) Brass -SR=Spiral Restrictor (high damping coefficient)

300 Series Stainless Steel⁷-WF=Weather Pack Connector, Female -WM=Weather Pack Connector, Male -DE = Deutsch Connector, Male, DT04 Series

6 Fixed Set Point (optional)

A. Specify set point -FS (in PSI or BAR, see example)⁸

B. Set Point Actuation

R on Rising Pressure

F on Falling Pressure

Example: -FS1BARF for 1 BAR Falling

or -FS20PSIR for 20 PSI Rising

Notes:

1. Manifold mounts available. Consult factory.

2. Requires -FL or -EL electrical termination.

3. 18" is standard. Specify lead length in inches (max. 48"). e.g. -FL18 or -FL30.

4. 18" is standard. Specify lead length in inches (max. 48"). e.g. -EL18 or -EL30.

5. DIN connectors require -C SPDT circuit.

6. Requires stainless steel pressure fitting.

7. -SR will result in wider deadbands and slower response times.

8. Set Point must be within Pressure Range selected in Step 1.

Repeatability and set point of units may change due to the effects of temperature.

In certain applications deadband can be tailored and controlled to customer specifications. Consult factory for details.

Operation of both switches in most cases will not be simultaneous but will occur within the specifications listed. Deadband figures

already reflect the improvement from the -RD option which is automatically included in the -AA, -BB and -CC circuits.
