Description
The Maury model A034B1 connector gage kit is designed to measure 3.5mm and 2.92mm (K) connectors with
either female or male interfaces.
CAUTION: Use your A034B1 for 3.5mm and 2.92mm (K) connectors only. Do not use for SMA connectors.
The Maury models A034B1 female and male connector gage assemblies simulate actual mating conditions al-
lowing high accuracy measurements. The connector gage assemblies are initially set to zero using master setting
gage, A027T1, permitting subsequent measurements to be read directly on the dial indicator. All machined parts
are made from non-magnetic stainless steel to assure long life and good stability. Gaging surfaces are lapped to
ensure a high degree of accuracy. A parts list is shown in Table 1.

MAURY MICROWAVE
The specications listed in Table 2 are the performance standards based on factory measurements traceable to the
U.S.A. National Institute of Standards and Technology (NIST).
To verify that your gage kit is performing to traceable specications, periodically send the kit to Maury Microwave
Corporation for calibration. The recommended calibration cycle is one year. The actual need may vary depending
on usage.
NOTES:
1Per ASME B89.1.10M-2001, C5.1.2.
2Per ASME B89.1.10M-2001, Table 2.
3Per manufacturer's specication.
4Operator skill has a great impact on repeatability. You can easily determine the repeatability of the connector
gages by multiple engagements of the master gages following the procedure outlined under Zero Setting on
page 5.
5Performance standards are in compliance with ANSI/NCSL Z540-1, MIL-STD-45662A and ISO 10012-1.
6Applies over the operating range for connector gaging +0.006/-0.003" from master gage zero setting.

NOTES:
1Female contact pin location.
2Male contact pin location.
3Tighter tolerances can be used at user's discretion.
4In reference to the outline above, Plus (+) tolerances indicate a recessed condition from the outer conduc-
tor mating plane.
Minus (-) tolerances indicate a protruding condition above the outer conductor mating plane.
5 Other dimensions shown in this gure are shown since they affect the mating of the Gage Assemblies'
gaging mechanisms (bushing and pin). Deviation from these dimensions may cause measurement errors
or improper t between the gaging mechanisms and the connectors being measured.
Consult our Customer Service Department on measuring connectors with interface dimensions other than
specied above.

Operation
Visual Inspection
Inspect all connectors carefully before each use. If a connector shows deep scratches, dents, uneven wear, or par-
ticles clinging to the mating plane surfaces, clean it and inspect again. Damaged connectors should be set aside
for repair. Also, try to determine the cause of the damage before making further connections.
Cleaning
Use dry compressed air of a very low velocity rst; then a solvent such as isopropyl alcohol. Clean the contacting
surfaces using a lint free swab. Then re-inspect the connector to make sure that no bers have been left around the
contact and mating surface.
CAUTION: For optimum measurements, never rotate parts against each other since this will yield faulty readings
and could damage the mating surfaces.
Verifying Zero Setting
The gage assemblies are pre-set at the factory for zero setting, however, the user should verify the zero setting prior
to each use as follows.
NOTE: The master setting gage is marked 'M' (male) and 'F' (female) to correspond to the 'M' and 'F' marked on
the indicator assemblies.
Procedure: Refer to Figure 3
Example for Zeroing Male Connector Shown (Applies Equally to Female Connector Gage)
1. Visually inspect the mating surfaces of your connector gage and master setting gage.
2. Clean both mating surfaces using the cleaning procedure above.
3. Align the connector gage and master setting gage. Carefully engage the master gage with the dial indicator
until the master gage seats securely. The dial hand should rotate clockwise and stop at zero after one or
more revolutions.
4. If resetting zero is required, engage the master gage, then while holding the dial indicator and master gage in
one hand, loosen the dial lock and rotate the bezel (outside rim on indicator) to the zero position indicated
by the hands on the indicator. Re-tighten the dial lock.

Gaging 3.5mm and 2.92mm (K) Connectors
The critical mechanical specication in precision 3.5mm and 2.92mm (K) connectors is the recession (setback) of
the center conductor relative to the outer conductor mating plane. No protrusion of the center conductor in front
of the outer conductor mating plane is allowable.
Gaging Female & Male Connectors
Contact Pin Location: Dimension 1 & 2 , Figure 2.
1. Using the gage assembly with corresponding 'F' (female) or 'M' (male) master setting gage end, check the
zero setting of the connector.
2. For Female: Carefully engage the female connector to be gaged to the female gage assembly. The gage
assembly bushing will slip into the connector and bottom on the outer conductor mating plane.
For Male: Carefully align the center contact pin of the male connector to be gaged so that it will enter the
hole in the pin of the male gage assembly. Engage straight on until the gage bushing bottoms on the outer
conductor mating plane of the male connector.
3. The pointer of the dial indicator will then indicate the deviation from zero. A minus (-) reading of the dial
shows that the center contact is below the outer conductor mating plane and a plus (+) reading shows that
the center contact is protruding past the outer conductor mating plane, which is not acceptable.
