A wide selection of power-off and fail-safe holding brakes are available for integration with Pittman brush-commutated and brushless DC motor products for customized brake/motor packages. All of the brakes are factory-installed to promote reliable, quick and hassle-free startup. Each delivers safe and energy-saving performance. The power-off brakes suit parking brake applications with their capability to decelerate and hold a load in position when power is deactivated. The holding brakes promote "fail-safe" operation by requiring power for their release. The power-off brakes include Type B30A in four models (supply voltages 12VDC, 19VDC, 24VDC, and 30VDC) and Type B49A in two models (supply voltage 12VDC and 24VDC). Standard features for both types include factory-set precision air gap, rigid molded friction disk, compression springs, and drive nuts with set screw. In addition, the B30A brake integrates MIL-W-22759/34D insulated lead wires and a low-profile mounting plate. Depending on model, static holding torque from 1 lb-in. (16 oz-in) to 3 lb-in. (48 oz-in) can be achieved. The family of holding brakes includes Types B7, B3, B6, and B5 in NEMA 17, 23, and 34 sizes supplied with 24VDC voltage. A clamp-in collar requires no motor modifications and allows users to simplify stocking by eliminating any need for custom product. The brakes' design allows coupling of NEMA output flanges to NEMA gear reducers. The brakes also can be specified with heavy-duty output shaft inputs to meet demanding application needs.

With the April issue, we celebrate the 40th anniversary of IEN Europe. For that occasion we present numerous interesting articles and interviews on technologies that have been groundbreaking over the past decades. An interview with Nexans is on the Evolution of Cables . A technical article by the EMVA on Machine Vision emphasizes the milestones that have been important for the automation industry. A very recent and up-to-date topic, Industry 4.0, is discussed in an Interview with Wibu Systems, a company dedicated to the protection of know-how. IEN Europe April also features a retrospective on Low-voltage Switchgear by Eaton. To celebrate IEN’s 40th anniversary properly, we have a Reader Offer for you, where you can win a high-tech visual IR thermometer. So please celebrate with us and enjoy!
