Position and Angle Measurement

The BML series from Balluff (Florence, KY) offers absolute position and angle measurement for installation or direct integration into drive and positioning systems. The magnetically encoded systems with Permagnet® nonius technology feature IP 67 housing for external installation. As an open kit for integration, they can be used in rotary applications as well. The formats, strokes, and end positions of axes can be adjusted automatically. The absolute encoder disk can be integrated into motors and actuators as an absolute feedback solution.

Linear Stage

Bell-Everman (Goleta, CA) offers the SLS Light sealed linear stage that keeps contamination such as manufacturing debris, particulate, or liquid contaminants outside of the stage housing. The stage measures 80 x 120 mm, and has maximum dynamic payloads of 15 kg for the direct drive linear motor version and 30 kg for the ball screw version. Both sizes deliver a proprietary linear lip seal design that integrates with the stage’s anodized aluminum housing. The seal is made from a ruggedized polyurethane elastomer and resists chemicals, temperature extremes, and mechanical wear. The seal can be replaced without disassembling the stage or removing payload. Applications include any application where contaminants can threaten the smooth operation of a linear actuator including laser machining, welding, semiconductor, and machining.

Piezo Drive

The Ensemble QDe™ desktop nanopositioning piezo drive from Aerotech (Pittsburgh, PA) was designed for seamless use with the Ensemble family of drives and controllers. The QDe connects to any Ensemble controller network, enabling coordinated motion between piezo stages and servo axes. The drive is suitable for single- or multi-axis applications such as point-to-point motion, linear and circular interpolation, multi-axis error correction, and autofocusing. High-speed interrupts and data logging capabilities provide a real-time link to external systems.

Motor Brakes

X-Small motor brakes from Warner Electric (South Beloit, IL) are spring-set holding brakes for applications in industries such as aerospace and medical equipment. The electrically released brakes are designed for engaged/disengaged holding applications such as seat adjustment on airplanes, but can provide a low-cycle-rate stopping action in emergency situations. They will remain engaged in the event of a power failure, making them suited to applications where integrity of the holding force is imperative. The brake range consists of six standard sizes from 22 mm to 33.5 mm diameter, and offers up to 50 Ncm of static torque. For Free Info Visit http://info.hotims.com/55593-303
