Laser Sensors

The optoNCDT 1750 laser sensors from Micro-Epsilon, Raleigh, NC, feature measuring ranges of 500 and 750 mm for fast, high-precision measurement tasks that require large measuring ranges. They are designed for industrial and automation applications, enabling measurements on difficult surfaces such as semi-transparent plastics and ceramics, PCB material, carbon, and glass fiber-reinforced plastics. The sensors operate almost independently of the material and color. Measured results can be obtained via analog or digital RS-422 interface.

Miniature Fasteners

microPEM® MSOFS™ flaring standoffs from PennEngineering, Danboro, PA, attach and/or space components in compact electronic assemblies. They install permanently in thin panels of any hardness and material, including stainless steel, other metals, plastics, and printed circuit boards. They feature a minimal footprint for reduced centerline-to-edge designs, and reusable threads to accept mating hardware. The fasteners are made of 300 Series stainless steel in thread sizes #0-80, #2-56, and M1 to M2.

Surge Resistors

The HPWC (high pulse withstanding chip) range of high-energy surge resistor products from TT Electronics, Woking, UK, are suited for protection and discharge applications in compact power supplies and power control circuits where a resistance tolerance of 5% is required. Available in four sizes from 0805 to 2512, the resistors withstand up to 6.5 kV peak for a 1.2/50 μs surge, and up to 3 kW for a 0.1 ms pulse. A compact PCB footprint minimizes use of the PCB area, and the absence of laser trimming means no current crowding.

Electronics Printer

Optomec, Albuquerque, NM, offers the Aerosol Jet HD System, a compact, configurable production platform that can dispense a range of electronics materials with features as small as 20 microns. The material deposition solution is used to directly print functional electronic circuitry and components onto low-temperature, non-planar substrates, without the need for masks, screens, or subtractive post-processing.

Frequency Synthesizers

Micro Lambda Wireless, Fremont, CA, released MLVS-Series frequency synthesizers for low-noise and fast-tune applications. A standard frequency model is available covering 500 MHz to 20 GHz, with options to cover down to 50 MHz and up to 21 GHz in a single unit. The standard model operates over the 0 to +65 °C temperature range, with extended temperature versions available. The frequency synthesizers have been designed in a miniature package that fits within a single-slot PXI chassis.

In-Circuit Debugger

Microchip Technology, Chandler, AZ, introduced the MPLAB® PICkit™ in-circuit programming and debugging development tool with a voltage range of 1.2-5V and USB connectivity. The tool is suited for designs in the 8-bit space, as well as for 16- and 32-bit development, using a 300-MHz, ATSAME70Q21B microcontroller onboard. The tool connects to the user’s computer via a high-speed USB 2.0 interface, and can be connected to the target using an 8-pin, single inline header that supports interfaces such as 4-wire JTAG.
