Potentiometer

Hoffmann + Krippner (Woodstock, GA) introduced the DL30 series linear motion potentiometer (transducer) series that features low-profile dimensions of 30 × 30 mm and variable lengths. Various types of resistors (e.g. wire, conductive plastic, and Sensofoil® membrane) are available. Features include compact design, rugged aluminum housing, and output options of 0/4mA, 20mA, or 0V-10V. They are available in lengths of 30 mm to a maximum of 500 mm. Resistor options are wire wound, conductive plastic, or an incorporated Sensofoil® membrane potentiometer. For Free Info Visit http://info.hotims.com/55590-315

Track System

Accuride (Santa Fe Springs, CA) introduced the Model AL4190 Tilt Track System that provides access to drawers or trays installed at shoulder level and above. The system uses wheels and rollers to extend the drawer, and an aluminum channel guides the back of the drawer upward as it slides out of the case, tilting the drawer downward for easy viewing and access to contents. The system carries drawers up to 40" wide and loads up to 140 pounds. The system is comprised of lightweight, corrosion- resistant aluminum tracks, roller wheel assemblies, and track rollers. Tracks are available in lengths of 24" and 40". The system is fully adjustable with the drawer in place. The installer can alter the angle of the tilt, which varies based on the angle of the track, attachment location of the track roller, and positioning of bumper stops.

Actuators

Nook Industries (Cleveland, OH) offers Series 500™ programmable actuators designed for continuous duty and long service life. They incorporate a direct or toothed-belt drive for high mechanical efficiency. Ball screw-driven programmable actuators are made with high-strength materials, and are available in parallel and in-line models with either a servomotor or stepper motor. The screw shaft is constructed with medium-carbon, induction-hardened alloy steel, and the ball nuts are manufactured from high-grade bearing steel. Both ball screw and nut are heat-treated to a surface hardness of 56 HRC.

Machine Control

Unitronics (Quincy, MA) has introduced Samba, a palm-sized PLC with HMI and onboard I/Os for machine control that features a color 7" HMI panel. The 16-bit touchscreen enables data entry and display of variable data, including color trend graphs and alarm screens. Samba supports 24 userdesigned screens and 5-MB images per application. The integrated PLC offers features including two auto-tuned PID loops, time-based RTC control, data logging, and recipes. The internal memory holds 112 KB of application logic, plus 512K for fonts and 5 MB for images. Onboard I/Os offer digital, analog, and high-speed functionality.

Accelerometer Chips

Silicon Designs (Kirkland, WA) offers industrial-grade MEMS variable capacitive accelerometer chips and modules for zero- to medium-frequency instrumentation applications. Onboard voltage regulation and an internal reference minimize temperature and voltage changes while eliminating additional external power regulation requirements. Each sensor is made to be virtually identical, allowing users to swap out parts in the same g range with few to no testing modifications. This also provides a plug-and-play solution for almost any application.

Sensor Beacons

EM Microelectronic (Marin, Switzerland) offers the EMBC02 sensor beacon, which integrates a 3- axis accelerometer. By attaching the device to objects or people, both proximity and motion can be monitored with a smartphone or tablet application. The EMBC02 can be programmed to transmit proximity, identification data, motion data (movements, vibrations, acceleration), as well as specific motion-based alarms based on accelerometer data originating from shock, free-fall, or taps. To maximize battery life, data is beaconed only when required, e.g. while in motion, or when an alarm condition occurs. The FCC/CE/IC-certified device is weatherproof and includes a multi-function input button and two LEDs for user feedback. For Free Info Visit http://info.hotims.com/55589-155
