Features

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

Temperature Sensors

Maxim Integrated (San Jose, CA) has introduced the MAXREFDES42# IOLink resistance temperature detector (RTD). The design’s integrated analog front end (AFE) also identifies overvoltage, shorts, and open circuits. The temperature appears immediately on an LED display.

Sensor System

Olea Sensor Networks (Sunnyvale, CA) has announced its OleaVision™ sensor system, which differentiates between live animate beings and inanimate objects up to a five-meter distance. To distinguish between human and animal presence and movement, the technology “sees” through walls, regardless of whether the monitored subject is moving or motionless. The sensor can be used in a variety of markets, including automotive/transportation, industrial, smart home and security systems (for pedestrian and bystander detection), collision avoidance, fire safety, and energy management.

Load Cells

Interface (Scottsdale, AZ) has released the Model 6AXX series of 6-Axis Load Cells. With six full bridges providing mV/V output on six independent channels, the load cells measure forces simultaneously in three mutually perpendicular axes, and three simultaneous torques about those same axes.
