GH Series connectors are high reliability, hexagonal
connectors offered with solder and straight solder termi-
nations. Contacts have 0.040 inch (1.02 mm) diameters
and are rated to 7.5 amperes per contact. Five connector
variants, four through ten poles, are offered.
GH Series connectors have DAPinsulators. Avariety of
plastic and metal hoods are available, and the locking
system is achieved by a lock-ring spring mechanism.
Polarization is accomplished by contact layouts or by an
oversized contact.
GH Series connectors are ideal for use in industrial and
instrumentation applications where light weight, miniature,
high reliability interconnections are necessary.
MATERIALS AND FINISHES:
Insulator: Glass-filled DAP per ASTM-D-5948,
Type SDG-F. Grey color is standard.
Fixed Contacts: Copper alloy, gold flash over nickel or
copper.
Hoods: Aluminium with yellow or black anodize.

Lock Rings and Lock Springs: Copper alloy with zinc plate and
dichromate seal.
MECHANICAL CHARACTERISTICS:
Fixed Contacts:
Male: Size 20: 0.040 inch (1.02 mm) diam-
eter.
Female: Open entry is standard. “Closed
Entry” is available on solder-style
contacts for high reliability applica-
tions.
Contact Retention in Insulator: 10 lbs. (44.5N), minimum.
Contact Termination: 0.046 inch (1.17 mm) internal diame-
ter on solder style contacts for 20
AWG (0.5 mm2) wire maximum
0.025 inch (0.64 mm) diameter
straight solder, printed board mount
style contact.
Locking Systems: Friction, lock spring with lock ring.
MECHANICAL CHARACTERISTICS, continued:
Polarization: 0.056 inch (1.42 mm) diameter male
contact in position “A” on Size 4 con-
nector. Molding configuration pro-
vides polarization on other sizes.
Mechanical Operations:
Open Entry Contacts: 250 operations per IEC 512-5.
Closed Entry Contacts: 500 operations per IEC 512-5.
ELECTRICAL CHARACTERISTICS:
Contact Current Rating: 7.5 amps, maximum.
Initial Contact Resistance: 0.010 ohms, maximum.
Flash over Voltage: 1,750 VAC (rms).
Test Voltage: 1,200 VAC (rms).
Insulation Resistance: 5 G ohms.

GH
SERIES
MGH Series connectors are microminiature, high relia-
bility connectors. They are available with three contacts
for providing polarization: two contacts at 0.030 inch
(0.76 mm) diameter, and one contact at 0.040 inch (1.02
mm) diameter . The MGH Series is rated to three amperes
per contact. Spacing between contacts is 0.102 inch
(2.59 mm), and the face diameter of the connector is
0.312 inch (7.92 mm).
MGH Series connectors are ideally applied where limit-
ed space is a concern. MGH Series connectors can be
used as cable connectors, panel-mounted connectors, or
probes. Constructed of high performance materials, MGH
Series connectors are widely used in medical, industrial,
military, and automotive applications.
