New Products
Electrically Conductive Gaskets

Data Storage System

Stockwell Elastomerics, Inc. (Philadelphia,
PA) announced EMI shielding gaskets and
sheet materials produced with nickel-coated
aluminum particles for long-term shielding
effectiveness and galvanic protection of electrical housings installed in harsh environments. Die cut gaskets or waterjet cut gaskets are available from .020 "
thick to .125 " thick, and compression molded gaskets are available
custom-molded from uncured compound. Two compounds are initially available. SNA-568 nickel-aluminum filled silicone is 68 durometer Shore A and will perform in most applications that need longterm EMI shielding and galvanic corrosion resistance. SNAF-572
nickel-aluminum filled fluorosilicone is 72 durometer Shore A. Fluorosilicone rubber provides enhanced resistance to swelling and deterioration when in contact with oils, fuels and fluids used in aviation.

Curtiss-Wright's Defense Solutions division (Ashburn, VA) announced the expansion of its family of solutions for unattended protection of data-at-rest (DAR)
with the introduction of the new UNS
Ground Station (UNS-GS) network attached storage (NAS) system.
The UNS-GS provides a ground-based complement to its popular deployable Unattended Network Storage (UNS) system. Both solutions
support NSA Certified Type 1 encryption for DAR using the General
Dynamics Mission Systems (GDMS) ProtecD@R® Multi-Platform Encryptor (KG-204). Classified data (up to 32 TB) is stored on Removable Storage Modules (RSM), which are used to transport data between the ground-based UNS-GS and deployed UNS. The UNS-GS
captures data via industry standard network storage protocols (NFS,
CIFS, iSCSI, HTTP, and FTP) through four 10 Gigabit Ethernet GbE at
speeds up to 2 GB/s.

Explosive Atmosphere Test Bench
Emitech Group's (Vendargues, France)
new bench is designed for carrying out tests
in an explosive atmosphere. These tests
specify the requirements and procedures for
aircraft equipment which could come into
contact with flammable fluids and vapors. The test bench has been designed to the following specifications: the chamber volume is 450
dm3, absolute pressure conditions up to 12,200 meters (40,000 feet) in
altitude, temperatures up to 120°C (248°F). Sealed passages are available in the walls of the test chamber to accommodate controls or supply to the equipment under test, for example electrical controls, fluid
supply or mechanical activation. The tests performed by Lefae comply
with the requirements of EUROCAT-ED-14D, RTCA DO-160, MILSTD-810 standards.

Hydraulic Aircraft Sealing Systems
Trelleborg Sealing Solutions Aerospace
(Stockholm, Sweden) launched the Turcon®
VL Seal® II for hydraulic sealing of actuators
in flight controls and landing gear, and seals
in landing gear shock absorbers. Based on the
original Turcon® VL Seal®, this new generation seal offers enhanced
sealing efficiency, easier installation, and even greater reliability. Compared to the Turcon® VL Seal®, the Turcon® VL Seal® II back-pumping
performance more than doubled up to 3,000 psi and nearly doubled at
pressures up to 5,000 psi. Accumulative leakage was around 4 milliliters less and significantly lower (around a half) from 1,000,000 to
2,000,000 cycles. Turcon® VL Seal® II is a unidirectional rod seal for reciprocating movements, consisting of an " L " shaped Turcon® jacket
energized by an o-ring. 'Sealed for life' means the seal lasts as long as
the actuator itself.

Gen 3 RFSoC Solutions
Pentek, Inc. (Upper Saddle River, NJ) announced extensions to their Quartz® RFSoC
product family by introducing the
QuartzXM eXpress Module, the Model
6003, adding greater RF performance and
scalability. The QuartzXM Model 6003, based on the Xilinx Zynq®
UltraScale+ ™ RFSoC Gen 3, provides full sub-6 GHz direct-RF I/O
support and greater flexibility with more decimation and interpolation options. It is ideal for 5G and LTE wireless, SIGINT, EW, communications and radar applications in SWaP-critical environments.
These new Quartz products support direct RF sampling using 5
GS/sec 14-bit ADCs and eight 10 GS/sec 14-bit DACs, both supporting analog signals up to 6 GHz. Each data converter has built-in digital downconverters or upconverters with programmable decimation
and interpolation up to 40¥.

Materials enhancements in two new electrically conductive elastomers from Laird Performance Materials (Santa Clara, CA) eliminate the
risk of galvanic corrosion and damage from fuel,
oils and deicing fluids in military and aerospace
applications. EcE 130 is an electrically conductive fluorosilicone elastomer featuring conductive passivated silver aluminum filler that offers high surface conductivity, eliminating energy leakage and reducing signal interference.
EcE 135 is an electrically conductive fluorosilicone elastomer featuring nickel aluminum filler. The nickel's inert properties are compatible with all other metals, offering better corrosion resistance than
other filler materials.
