Service Class F Amphe-Lite M3 uses superior silicone seals providing increased fluid resistance.
2.
Provides excellent
EMI
shielding and grounding through 100% metal to metal bottoming.
3.
Acme threads provide coupling durability. Completely mates
in
one 360-degree turn
of
the coupling nut to provide
the fastest and easiest equipment assembly and maintenance possible.
4.
Recessed pins minimize potential contact damage
in
this 100% scoop-proof connector.
In
a blind mating
application, mating shells cannot scoop the pins and cause a shorting or bending
of
contacts.
5.
A rigid dielectric insert with excellent electrical characteristics provides durable protection to the contacts.
6.
With Gray ZnNi Plating the connector can reach 500 salt spray hours and is RoHS compliant.
Features and Benefits For Amphe-Lite M3
• Acme threads provide coupling durability and quick-mating.
High Vibration Resistance.
• High-density connectors suitable for small footprint designs.
Using crimp contacts, able to be removable.
• 100% scoop-proof shells.
• Self-Locking Threaded Coupling.
• 9 shell sizes and 5 Keyway options are available to eliminate mismating.
• 17 insert patterns with a sandwich structure design rated to IP67
in
the mated condition. Contacts for
printed circuit board and fiber optics are available upon request.
• Amphe-Lite M3 can withstand 500-hours
of
salt spray corrosion when plated with our Gray
Zn
Ni
plating
suffix
is
072.
• Amphe-Lite M3
is
able to
