1 Pressure Range Code

Insert Pressure Range Code from Table 1, below.

2 Pressure Fitting

1

12L14 Zinc-Plated Steel

-2MNZ = 1/8˝ NPTM 12L14

-4MNZ = 1/4˝ NPTM 12L14

-2MGZ = 1/8˝ BSPM 12L14 (G type)

-4MGZ = 1/4˝ BSPM 12L14 (G type)

-4MSZ = 7/16˝-20 SAE Male

-6MSZ = 9/16˝-18 SAE Male

-M10Z = M10 x 1.0, Straight

5 Options

-G = Gold Contacts
(for loads less than 12 mA @ 12 VDC)

-IP = Ingress Protection

-IPA = Removable Silicone Seal for
Set Point Adjustment

4

5

-R = Restrictor (low damping coefficient) Brass

-SR = Spiral Restrictor (high damping coefficient)
12L14 Steel w/Black Oxide Finish

6

-OF = Oil Free Cleaned (requires SS housing)

-RB = Rubber Boot (shipped loose)

-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)

7

Notes:

1. Other fittings available.
Consult factory.

2. 18˝ is standard. Specify lead
length in inches (max. 48˝).
e.g. -FL18 or -FLS30.

3. 36˝ is minimum. Specify
cable length in inches. e.g.

-CAB36 or -CAB120.

4. Ingress Protection is
available only with -FL, -FLS
or -CAB Electrical
Termination choices.

5. IPA protection is available
only with -FL or -FLS.

6. -SR will result in wider
deadbands and lower
response time.

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

B. Set Point Actuation
R on Rising Pressure
F on Falling Pressure
Example: -FS3BARF for 3 BAR Falling
or -FS60PSIR for 60 PSI Rising

Table 1 — Pressure Range Codes

Pressure Range Code Pressure Range Accuracy* Average Deadband**

10 15-60 psi (1-4 bar) ±1.5 psi (0.10 bar) +4% of setting 3 psi (0.21 bar) +6% of setting

20 40-150 psi (3-10 bar) ±2.5 psi (0.17 bar) +4% of setting 5 psig (0.34 bar) +7% of setting

30 75-275 psi (5.2-18.9 bar) ±3.75 psi (0.26 bar) +4% of setting 7 psig (0.48 bar) +9% of setting

40 150-600 psi (10.3-41.4 bar) ±5 psi (0.34 bar) +4% of setting 10 psi (0.69 bar) +11% of setting

* Accuracy 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.
