Omron has designed a relay that can interrupt 200A at 500V, aiming to displace contactors from dc electric vehicle chargers, batteries and solar inverters. “A proprietary gas-less design cools arcs without the need for any special parts or materials in the manufacturing process, while eliminating the possibility of gas leakage,” according to the company. Gas-less? “G9EA, G9EC, and G9EH relays ...

Frore Systems has chosen Nvidia’s Jetson Orin Nano Super single-board computer as the latest platform on which to demonstrate its novel ‘solid-state’ cooling ‘fans’. This version of the mems-based air shifter, PAK 5C-25, measures 100 x 65 x 9.8mm and can remove up to 25W of heat, according to Frore, meeting the needs of the 67Top/s (INT8) Orin Nano Super ...

Nisshinbo Micro Devices has launched the NT1821 and NT1822 High Isolation SPDT Switches are engineered to meet the demands of Wi-Fi 7 infrastructure and other wireless communication applications. The NT1821 is specifically designed for wireless communication systems, with a particular emphasis on Wi-Fi 7 applications. It supports functions like transmit/receive switching and antenna switching. It covers a frequency range from ...

Toshiba is aiming at 400V automotive systems with a 400V photo-relay that can handle 900V and ~30mA. Recommended maximum operating voltage is 720V. Called TLX9150M, it measures around 10 x 8 x 2.5mm and can carry 50mA at 25ºC, 20mA at 105ºC and 10mA at 125ºC, or 1ms pulses of 150, 60 and 30mA respectively. The package, SO12L-T has 8mm ...

Toshiba has released a “high-speed” low-voltage photo-relay “particularly suitable for the pin electronics of semiconductor testers”, it said. High-speed? “Turn-on switching time is below 80μs,” according to Toshiba. “Compared to the previous generation – TLP3450 – this represents a 40% improvement.” It has a single normally-open ‘contact’, consisting of back-to-back mosfets making it suitable for switching ac or dc signals. ...

Delo has developed a transparent adhesive for bonding automotive headlights. “Photobond OB4210 is characterised by its yellowing stability at high temperatures” according to the company. “Manufacturers of automotive headlights can use it to realise optically sophisticated applications – the  transparent characteristics make it hardly distinguishable from the lens material.” Transparency is typically retained after a 500 hour storage at +140°C. It ...

Chomerics announced a cure-in-place thermal gap filler material that remains flexible after curing, at Elecronica today. CIP 60 offers 6W/mK conductivity, and cures to a Shore hardness of 50 (ASTM 2240 method). “This not only provides an alternative to hard-curing dispensable materials in electronics cooling applications, but also offers an improvement over standard application methods associated with thermal gap filler ...

Chomerics has formulated a thermal gap pad with low oil bleed, low oil migration “ideal for use where the appearance or production issues of silicone oils are undesirable, according to the company. ‘Pad 80LO’ (LO = low oil) has a typical thermal conductivity of 8W/mK and Shore 00 hardness of 60. Stress relaxation over time is nearly 90% reduction in ...

Inelco Hunter is stocking low-profile printer mechanisms for ‘2inch’ thermal paper, from FCL Components. FTP-62GMCL173 (pictured) measures 76.2 x 20.4 x 36.3mm FTP-62GMCL473 adds a slim auto-cutter to the front and measures 80.5 x 34.8 x 45.6mm Formerly, the above are 58mm (±1mm) printers. There are also 60mm types, identified by adding an #01 suffix. Paper thickness can range across ...

Littelfuse has introduced a ‘tact’ style push-button with change-over contacts. ‘KSC DCT’ as it will be known, has a 6.2 x 6.2mm surface-mount body and is sealed to IP67. Both gull-wing and J-lead leg variants are available. “Everyone can now precisely monitor the actual status of an electromechanical surface-mount technology tactile switch, even when the switch is not in use, ...
