LEMO M Series range of triple-start micro-connectors
provide significant space savings in comparison to MIL
38999 Series III connectors, and are LEMO’s smallest
multi-pin, fully shielded, vibration-secure and sealed
connectors available, offering a lightweight connection
with high pin-count density, 360º EMC shielding
protection, and LEMO rugged quality.
•
LEMO M-Series high-strength aluminium connectors
incorporate a triple-start fast-locking ratchet mechanism
for use in high vibration and harsh environments,
providing significant size and weight advantages over
MIL-38999 connectors and other micro circular
connectors. Already selected for use on the F1ECU
and a number of military and avionics applications,
the M Series is continuing
the excellent reputation
of LEMO connectors’
for high quality and
reliable interconnection
solutions that meet
customers requirements.
Main features and benefits include:
•
Unique LEMO precision gold-plated contact
system for exceptional performance and longterm reliability
•
With power pin and reduced crimp barrel
contacts, accommodates wire from 16 to 32 AWG
•
•
•
•
•
Triple-start thread ratchet coupling mechanism
for fast (3/4 turn) & secure connection
Small size with high contact density for
significant space savings
Multiple keys and keyways for ease of mating
and security
Short flange to pcb depth for greatly reduced
enclosure sizes and cost savings
Integral backshell, but with MIL backshell
options if preferred

M-Series
Designed for use in harsh environments, M Series
connectors have been tested to the full range of MIL
tests including vibration, gunfire, altitude, lightning,
temperature, immersion,chemical and flammability,
clearly demonstrating capability of the range to handle
many aerospace, military and security applications.
This catalogue provides a summary of the M Series
range and accessories with comparisons to some
popular MIL 38999 shell sizes to demonstrate the
potential equipment savings that can be made by
adopting the M Series.
Note that this catalogue does not cover the whole
M Series range and other housings are available –
some examples below. The full catalogue giving full
details of the complete M Series range is available
via our website – www.lemo.co.uk
The M Series has a wide range
of shell design options to suit
customer requirements.

LEMO to see if the configuration you
require is available. All contacts other
than for pcb are crimp contacts for
which you will need a standard style

Backshells
A range of backshells have been specially designed
to be fitted to the LEMO M Series connectors where
customers require the additional benefits of a separate
backshell – note that the M Series has an integral
backshell. The design is shorter than standard MIL
spec adaptors in order to complement the space
savings offered by the M Series.
LEMO backshells are available in 3 primary models –
straight, 45º and 90º – and are manufactured as
standard from the same lightweight high strength
aluminium as the M Series. Other materials are
available on request.The rear fixing channel is
designed to take metal tie-wraps or spring clips,
depending upon the customer’s preference.
Part number structure
A slotted option is available for termination of
additional drain wires.
The connector interface is to the MIL 38999 Series III
and IV shell sizes and a range of cable entry
diameters are offered. Part number structure is
shown below (add “M” to the end
of M Series part number for the
correct interface).

Microbands and Constant Force Spring clips for screen termination
Termination of the cable screen to M Series
connectors can be achieved through the use of either
metal microbands or constant force spring clips. The
closing of microbands requires the use of a special
tool to ensure sufficient tightening of the band,
whereas the spring clips are manually applied and are
contained by a the heatshrink boot.
Microband tool
Part Number
A30199
M Series Constant Force Spring Clips
A range of constant force spring clips are available for
use with M Series connectors, which permits repair of
cable terminations without having to discard any of the
existing braid shield system. When used in conjunction
with LEMO heatshrink boots, a fully sealed termination
is achieved. An additional benefit
of the constant force spring
isthat it provides excellent
resistance to shock or
vibration due to its
self-tensioning properties.

Cable assembly
LEMO UK offers a full cable assembly service from its
modern facilities with fully trained technicians, and we
pride ourselves on the quality of the terminations provided.
CAD drawings are created for new assemblies and are
fully structured on our system to provide appropriate
controls & full traceability.
Whilst our emphasis is naturally on the termination of
LEMO connectors, we have extensive experience of
connectors from other manufacturers.
LEMO UK has the capability for termination of both
copper and fibre optic cable assemblies.
At LEMO every cable assembly is fully inspected to
ensure it meets the required standard.
In many instances the technical requirements for an
assembly are the same for many different customers.
For this reason a part numbering system for M Series
standard cable assemblies has been created, where the
specification is a text description based on DEF STAN
61-12 standard cables and standard pin-outs to match
the connector. Variants according to customer
requirements can be accommodated, though the part
numbering will be different and will be generated at the
time of an order.
Short run cables can be made up to suit customer
requirements.
