Omron is aiming at test and measurement with a miniature 200V 350mA mosfet opto-relay. In a 3.4 x 2.1mm P-SON (power small outline no lead) package and operating across -40 to +110°C, “this device can realise a current load of 75% higher than a comparable SOP4 type relay”, said the company, justifying this with the figure 49mA/mm2 for the P-SON relay and ...

Vishay has released a family of six high-power infra-red emitters in 3.4 x 3.4mm lead-less packages. They are “designed with a 42mil chip for 1.5A dc operation, with  support for pulsed currents up to 5A”, according to New Yorker Electronics, which is stocking the parts. They come in two wavelengths and three viewing angles. The parts are: VSMA1085400 860nm 925mW/sr ±40° VSMA1085250 ...

Excelitas has introduced a precision-aligned 2W xenon light engine for light-based measurements. Called µPAX-3, it includes an EMI-suppressing enclosure, the xenon flash lamp light source, a trigger circuit and a power supply – all within 42mm square by 31mm deep (plus connector), which is smaller and more robust than the existing µPAX-2, according to the manufacturer. “These miniaturised modules can ...

Advanced Energy of Colorado has introduced single-phase hot-swappable PSUs up to 4kW for horticultural and commercial LED lighting. “Indoor growers are turning to centralised power systems that distribute dc rather than ac power directly to individual LED lamps”, said company v-p of industrial power Joe Voyles. The supplies, called the LCM4000HV series, are compliant with DesignLights Consortium (DLC) technical requirements ...

A new partnership between Anglia Components and Cumbria-based LED manufacturer, Marl International, cements the distributor’s status as Master Distributor for the UK and Ireland, covering the full range of panel lamps, PCB mounting indicators and other standard LED components. As Master Distributor, Anglia will carry “an extensive” stock of standard devices for customers and for other resellers, but will also offer support ...

Toshiba has introduced a photo-relay capable of operating with 1.5kV across its output switch – the company’s first with such an output withstand voltage – “ensuring that it is compatible with the vast majority of traction batteries”, it said. AEC-Q101 qualified and aimed at battery management systems, TLX9160T consists of an infra-red emitting diode optically coupled to back-to-back photo-mosfets. Although intended ...

Osram has revealed a prototype laser emitter module for projection within augmented reality glasses. The lasers are 640nm red, 520nm green and 450nm blue, in a 7 x 4.6 x 1.2mm (39mm3) surface-mount package. Branded Vegalas, the “prototype design for the module demonstrates that a light engine for smart glasses can be compact enough to fit in standard consumer fashion frames”, ...

Anglia Components has signed a UK and Ireland distribution  agreement with Chinese LED maker Ekinglux. “We are always seeking to strategically expand our supplier base to stabilise our supply chain.,” said Anglia technical director David Pearson, “The addition of Ekinglux, one of China’s top ten LED manufacturers, widens the range of optoelectronics devices we offer. Ekinglux has an excellent reputation for quality and ...

Toshiba has launched three quad Form-A voltage driven photorelays, claiming one of them with one of the smallest mounting areas in the industry. They are Toshiba’s first four-circuit, 4-Form-A, relays, in a 12.5mm2 (2 x 6.25 x 1.3mm) package dubbed S-VSON16T. “The area is approximately 14% less compared with the mounting area of four one-channel relays,” according to the company. ...

Osram has introduced a laser diode for industrial lidar. SPL TL90AT03 emits 905nm infra-red and has been developed for short laser pulses – between 5 and 100ns – maximum duty cycle is 0.1%. Optical output is 65W from a 110µm aperture (20A 100μs 1kHz) – said to be an efficiency of 34%. There are three emitters inside the package – forward ...
