Toshiba has launched two normally open 1-form-A photo-relays that do not need more than 2mA through the input to operate. The input current “reduces energy consumption by approximately 33% when compared to existing Toshiba products such as the TLP240x series”, according to the company. There are two parts: TLP223GA 400Vmax 120mA 17Ω output turn-on 1ms ...

Elastomer electrolytes might be the answer to safe lithium-metal batteries, according to researchers at the Georgia Institute of Technology. Batteries using lithium metal anodes rather than lithium ions promise high capacities, but a tendency to grow internal cell-shorting spike-like metal dendrites makes them a risky, or even unsafe, proposition if liquid electrolytes are used. Solid ...

Yokowo has developed a waterproof blade and receptacle connector with floating contacts to absorb mating misalignment, vibration or shock. Spring-loaded dual-beam contacts absorb contact displacement – 0.3mm laterally (left-right in the photo insert), for example. The base of the connector is ~22mm long (including small tags). Contacts are rated at 3A with 50mΩ contact resistance and a life ...
