SmartSwitch with 3D CAD File
NKK Switches 3D CAD file downloads for its SmartSwitch (www.nkksmartswitch.com) simplify engineers’ efforts in PC board and panel design, including space studies and design efficiencies. The programmable LCD switches can display a wide variety of text, graphics with real-time sequencing or moving images to simplify complex, multi-decision operations. With typical forward current rated at 15 mA and typical power dissipation rated at 130 mW, the units meet low energy consumption criteria for panel designs. The compact version of the switch introduced in 2006 has similar electrical and performance specifications to its larger predecessor but fits into a smaller footprint. The unit’s LCD has a viewing area of 13.9 X 10.6 mm with a 36 X 24 pixel resolution to maximize clarity. With the newly available CAD tool, engineers can easily design the switches into applications such as industrial control panels, communication systems, audio-video broadcast workstations and simulation equipment.
Gigabit Ethernet Vision CableNorthwire, Inc.’s GEV-1000 cable (http://www.northwire.com/custom/datacell/), part of the company’s high-flex DataCELL cable family, is designed specifically for the GigE (Gigabit Ethernet) Vision market. A 60-meter assembly was tested and confirmed conformance with Near End Crosstalk (NEXT), characteristic impedance, length, return loss and High Definition Time Domain Xtalk (HDTDX) parameters. Operation has been verified with a Gigabit Ethernet camera at a rate up to 60 frames per second. The product builds on the company’s experience with other high data rate and mechanically rugged cables that include Field Bus, MVC-800 FireWire and J-1939 Vehicle Bus cables. The high-flex cable interfaces with standard and specialty Ethernet cable connectors. With dual shields (braid and foil), industrial-grade construction and a weld flash-resistant TPE outer cable jacket, the cable targets industrial motion applications. In addition, the cable’s oil and abrasion resistant allow usage in outdoor installations. Cost-Effective Photoelectric Sensor
Tri-Tronics MiniEye miniature photoelectric sensors (http://www.ttco.com/products/minieye.aspx) provide economical performance in space-conscious situations. At $39 in OEM volumes, the units target cost-sensitive applications but still provide several useful features for presence and absence detection. Units are offered with either an infrared (IR) or red LED light source, and either NPN or PNP output transistor. With high speed operation within 600 ìs (1.1 ms for the opposed mode), the IR sensors are easily applied to opaque object sensing tasks as well as sensing translucent or transparent objects in the proximity (beam make) mode. The red LEDunits easily sense translucent or transparent objects in the proximity mode and can be polarized for retroreflective sensing to reduce the measurement problems from shiny objects. Fixed optics address proximity, retroreflective, polarized retroreflective, and thru-beam operation. The unit is immune to indirect ambient light and strobes and its waterproof, high-impact housing allows operation in harsh environments.
Microfluidic Flow Sensor
Sensirion AG’s MEMS-based liquid flow sensors for microfluidic systems (www.sensirion.com/liquidflow) weigh only 6 grams but handle flow rates up to 3 ml/min. The design integrates the sensor and its digital circuitry for linearization and temperature compensation in a single chip for size, weight and cost reduction. Since the semiconductor sensor chip is mounted on the outside of flow path and senses through the wall of the channel, Polyetheretherketones (PEEK) or fused silica (glass) channels isolate the liquid media.The design allows media detection and accurate measurement of liquid flow rates down to nl/min. With response times in the millisecond range, the sensors enable the monitoring and controlling of dynamic effects in microfluidic systems. Target applications include analytical instruments, medical devices and life-science applications.
Wet-Wet Differential Pressure Sensor
Measurement Specialties DP86 differential pressure sensor are designed for wet-wet applications (http://www.meas-spec.com/myMeas/download/pdf/english/icsensors/pressure/stainless_steel/DP86.pdf) in OEM equipment where corrosive gas or liquid level needs to be controlled. Packaged in a double-sided, 316L stainless steel housing, the piezoresistive silicon pressure sensor’s media compatible design allows use in liquids and corrosive environments. The physical dimensions match the company’s Model 86 pressure capsule, a common size used in industry. Designed for O-ring mounting, with silicone oil transferring pressure from the stainless steel diaphragm to the sensing element, units are available in seven different pressure ranges. The low-pressure model is 0 to 5 psid and six other ranges address measurements from 0 to 15 up to 0 to 500 psid. Target applications for the differential pressure sensor include tank level measurements, liquid and gas flow, water management, hydraulic systems, filtration, refrigeration, compressors, and others.
