asterLatch (GMLM) Quick-release locking Micro-D connector pairs are equipped with
a precision latching and locking mechanism. The single thumb latch on the plug side
actuates a pair of locking latches that mate quickly and reliably to GMLM receptacles. These
TwistPin equipped, low-insertion-force connectors meet all the standard performance
requirements of MIL-DTL-8513 including vibration, shock, and mating durability. Choose
from 7 different insert arrangements from 9 to 51 way. The unique ergonomic latching
mechanism can be easily activated with a thumb and forefinger grip even when wearing
gloves, or when difficult access to connector pairs makes the use of jacking hardware and
tools impossible.
