interface, which can confirm parameters in real time
without stopping motors by loading parameters relevant
to motor control to RAM. A self-diagnostic function
that confirms the reference voltage of the ADC, and
a CRC arithmetic circuit that identifies incorrect
detection for every read operation of the memory are
also incorporated. These support load mitigation of the
software process required for functional safety[2].
Offering pin counts from 32 pins to 64 pins, the new
devices are available with flash memory capacities
from 64KB to 128KB. Communication options comprise
UART, TSPI and I2C interfaces, while I/O ports range
from 24 to 52. Operating voltage range is from 4.5V
to 5.5V. Toshiba’s integrated Advanced Vector Engine
Plus (A-VE+) supports vector control and dead-time
compensation, while an advanced programmable motor
control (A-PMD) circuit delivers 3-phase output and
supports 3-phase interleaved PFC.
Products with a wide pitch for flow mounting and a fine
pitch for reflow mounting are included in the line-up.
Operating temperature is from -40 to +105°C.
TT Electronics set to revolutionise the
soldier wearables market with its auto-aligning
and self-coupling textile-mounting garment
connector
mag-Net® offers invisible power and data connectivity
with incredible ease-of-use, dependable reliability,
improved mobility and superior human factors
Woking, UK, 28 September 2016 – TT Electronics,
a global provider of engineered electronics for
performance critical applications, today launched its
mag Net® soldier connector, the world’s first and only
C4I2 MIL-spec connector specifically designed for textile
mounting. Unlike circular barrel connectors, mag Net®
is a robust, flush rectangular solution with a self-aligning,
automatic magnetic latching system that enables the
easiest ever, one-handed blind mating. This system will
be showcased by TT Electronics at the AUSA Exposition
in Washington, October 3-5, 2016.
Intended for equipment connection to soldier-worn
garments and load-carrying systems, the mag Net®
design provides mechanical latching with no moving
parts for reliable, jam-free operation. Together with
an ultra-lightweight, no-bulk design that maximises
mobility and eliminates cable snag hazards, mag Net®’s
abrasion-resistant, flush-flat receptacles are virtually
self-cleaning and require no protective caps, ensuring
maximum durability and full environmental-sealing, both
in mated and un-mated conditions. The 8-way contact
configuration supports power up to 8Aand USB 2.0 high-
speed data transmission. Cable plugs can be oriented to
allow for cable entry in any direction.
TT Electronics’ beta and alpha testing of the mag Net®
connector system has received very positive reactions
from various military authorities and the manufacturers
of rugged equipment. These include: “This is clearly
the next generation, it makes all other soldier vest
connectors look stone age” and “I think that this really
is the future”.
The garment part of the mag Net® connector system
comprises two elements: A low-cost, garment cage
made of thermoplastic, which is strong, durable and
chemical resistant, can be easily and securely sewn
into clothing by garment manufacturers who may not
necessarily be skilled in the integration of expensive
wearable electronics. This non-polarised cage provides
an aperture into which the second element, the connector
receptacle, can be fitted with the desired orientation.
The receptacle itself features a ruggedised, lightweight
shell and thermoplastics carefully chosen to provide
maximum abrasion resistance. The magnets are fitted
under the front face of the insert, which is flush to allow
easy finger-wipe cleaning, while removable sides in the
backshell enable cable or e textile entry from 4 possible
directions. Once terminated to the wiring harness, the
receptacle is introduced into the cage from behind.
The mag Net® plug connector can be fitted to equipment
such as personal role radios (PRRs) or batteries,
providing a direct connection to the vest. Plugs feature
‘pogo’ spring contacts, machined from copper alloy, for
high mating cycle resilience and easy cleaning, with
an optional first-mate, last-break contact configuration.
At the rear, PCB tail contacts provide for flex-print or
regular PCB termination. An ‘O’-ring gasket and blind
