Laser-Markable Compounds

RTP Company, Winona, MN, has developed a series of thermoplastic compounds formulated specifically for allowing high contrast marks and images to be added to an application via laser processing. A variety of polymers, including clear substrates, can be compounded to optimize laser marks, which eliminates the need for inks, paints, and dyes, thus saving on processing costs. The laser-markable compounds are available in a variety of resin and additive combinations that are custom formulated, colorable, and optimized for multiple laser technologies. In some cases, compounds can be formulated with biocompatible ingredients. Devices made from the compounds provide durable and wear-resistant marks for compliance with FDA’s UDI.

Accelerometers

Silicon Designs, Kirkland, WA, has released a low-noise single-axis accelerometer. The Model 2210 Series integrates a MEMS VC accelerometer chip with high-drive, low-impedance buffering for reliable, repeatable measurements. When used with the company’s mounting block, such as the Model 2330-BLK, the module can effectively measure on either one, two, or three axes, allowing for the specification of a single part number for multiple requirements. Offered in ranges from ±2 to ±400 g, the module generates two analog voltage outputs, which vary in response to applied acceleration. It is available with single-ended or differential output. Differential output doubles accelerometer sensitivity over single-ended versions.
