PS76 -10 -4MNZ -C -H -XX -XXXX

12 3

1 Pressure Range Code

Insert Pressure Range Code from Table 1, below.

2 Pressure Fitting¹

12L14 Zinc-Plated Steel -2MNZ = 1/8"NPTM -4MNZ = 1/4"NPTM

-4FNZ = 1/4"NPTF

-4MGZ = 1/4" BSPM (G type)

-4FGZ = 1/4" BSPF (G type) -4MSZ = 7/16"-20 SAE Male -6MSZ = 9/16"-18 SAE Male

-4SSZ = 7/16"-20 SAE Male Swivel

316L 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

-ELXX=1/2" NPT Male Conduit w/Flying Leads⁴-H = DIN 43650A Male Half Only⁵-HR=Right Angle DIN 43650A Male Half Only⁵-HC=DIN 43650A 9mm Cable Clamp⁵-HCR=Right Angle DIN 43650A 9mm Cable Clamp⁵

-HN = DIN 43650A with 1/2" Female NPT Conduit⁵-HNR=Right Angle DIN 43650A with 1/2" Female

NPT Conduit⁵

5 Options

-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.

40	500-1750 psi (34.5-121 bar)	±35 psi (2.41 bar) +4% of setting	45 psi (3.10 bar) +13% of setting

* 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.
