at sea level
wall mounting receptacle
with wide flange
Quick positive coupling assured by 3 point bayonet coupling
system

coded (three colour bands), and are crimped with standard crimp
tools per MIL-C-22520
Grommets are constructed of tear-resistant
elastomer and experience no degradation when exposed to a
broad range of fluids
Sealing over a range of wire diameters is assured by a triple
webbed grommet at the rear of the connector
MS3474
Closed entry socket side of the insert is designed with a lead-in
chamfer and a hard face that will accept a pin contact bent within
pre-established limits
jam nut receptacle
Elastomer interfacial seal on the pin side has raised barriers
around each pin which displace into the socket chamfer when
mated, providing a positive moisture seal

** Service rating is comparable to MS rating A. Miniature connectors rated Service Rating I will provide a
minimum flashover voltage at sea level of 2000 volts AC (RMS). Service rating II is comparable to MS Service
Rating D, and will provide a minimum flashover voltage of 2,800 volts AC (RMS) at sea level.
Please note that the electrical data given is not an establishment of electrical safety factors.
This is left entirely in the designer’s hands, as he can best determine which peak voltage, switching surges,
transients, etc. can be expected in a particular circuit.
