stanD-off voltage valUes for cell delivers high
equipment where high voltages are involved. The devices are also suitable where mains voltages switch, for example to control and isolate S.C.R. or triac gates. Four types of dry switches are
available for stacking on 0.25 inches pitch and are capable of standing-off 1.5, 2, 3 or 4kV DC. The 3kV and 4kV versions benefit from an increased clearance between the switch and coil pins to accommodate the higher voltage. Higher voltage ratings are available on request. The Series range features one or two
switches in a single package, 1 Form A, 2 Form A and 1 Form B configurations as well as 5V, 12V or 24V coils with optional internal diode. In addition, the internal mu-metal screen eliminates problems that would be experienced due to magnetic interaction when the relays
Pickering Electronics has increased the stand-off voltage values for its small-size Series 104 high voltage reed relays for up to 4kV. For the newly introduced versions, this means a 1000VDC stand-off voltage improvement on the previous Series 104 product offering. These voltage isolation reed relays are suitable
for use in applications such as transformer and cable testing or any other automatic test
are closely stacked. Mercury wetted devices are also available
for applications where bounce free switching is required. These are rated at 1500 volts DC minimum stand-off & 500 volts DC switching at up to 50 watts.

Toshiba Corporation has expanded its SCiB product offering with the launch of a 20Ah-HP rechargeable lithium-ion battery cell that delivers high energy and high power at the same time. The cell is ideal for heavy-load applications
where high power input and output are essential, and for situations where battery cells must suppress heat and operate continuously, such as rapid charging of commercial vehicles, regenerative power systems for rolling stock, and industrial equipment. Furthermore, it is the same size as Toshiba’s current 20Ah product, allowing current customers to easily upgrade to the improved input and output power with the same module pack. Compared to Toshiba’s current 20Ah cell, the
new 20Ah-HP cell delivers 1.7x higher input and 1.6x higher output, realised by an approximately 40% reduction of resistance in the cell. It also achieves a longer life than the current 20Ah cell by suppressing heat during continuous charging and discharging, due to its lower internal resistance. Toshiba expects to see the new cell deployed
in automobiles, industrial equipment, and storage battery systems.

Using D38999 connectors in challenging environments
applications and D38999 connectors facilitate this since their backshells and contacts are easily customisable. For example, backshells can be supplied in aluminium, stainless steel or composite materials depending on the requirements. Composite options are much newer and are growing in popularity because they are lightweight and offer high performance levels in harsh environments. They are also REACH compliant and QPL qualified for use in military applications. PEI-Genesis provides an extensive range of
Whether they’re used in a commercial aircraft or onboard a military vehicle, not many electrical components are subjected to extreme conditions like connectors are. Here Emily Rowe, European Product Manager at mission critical electrical connector specialist PEI-Genesis, speaks to Design Solutions about the benefits of using D38999 connectors in these applications. Electrical connectors must endure extreme
conditions on a regular basis. Often subjected to rapid temperature variations or persistent vibrations, impacts and signal interference, they must be robust enough to continue operating reliably and safely under these conditions. Take the industry standard D38999 connector.
This is a military-specification electrical connector, originally designed in the 1970s, that is now on its third-generation design. The main reason the D38999 connector soared to popularity is that it
offers a much higher density of contacts than its predecessors — 128 contacts compared to only 19 for 5015 connectors.

In military applications, we are seeing an increasing need for shielding and durability, with electrical connectors expected to be in service for up to 20 years. This is an area where D38999 connectors shine. With life spans between 500 and 1,500 mating cycles, they can last for up to 30 years depending on the application. Many customers from the
aerospace and military industries require custom components for their
D38999 connectors from Amphenol, ITT Cannon, TE Deutsch, Souriau Eaton and Conesys. Not only that but it also stocks large volumes of component parts and is able to build millions of connector types while offering lead times of 48 hours from the moment you place your order. Furthermore, it can offer standard solutions or
work with customers to create something bespoke for their specific application using its in-house team of design engineers. This is in addition to the fact that it supplies a wide range of accessories for D38999 connectors such as protective caps, backshells, contacts, nut plates for receptacles
and tooling. PEI-Genesis
