Automotive Grade, Hall-Effect Sensor Offers 2.1 kVrms Isolation

December 17, 2007 6:28 am | Comments

Allegro introduced two current sensorsfor AC and DC currents in automotive applications. The ACS714 and ACS715 devices are akin to the company's ACS712 and ACS713 devices, which are specialized for low current sensing in non-automotive applications. The differences are realized in the more rigorous test regiment over the full automotive temperature range (-40°C to +150°C) and the greater detail

Photoelectric Sensors Provide Quick Response Time

December 17, 2007 6:28 am | Comments

Pepperl+Fuchs introduced the GLV18 Econo-Vue Photoelectric Sensors in a compact, short housing that provides greater mounting flexibility.  The series is available in five different sensing modes and provide sensing ranges up to 20 m.  All models are available in straight and right-angled housings, cabled and quick disconnect versions, and come standard with a flush mount bracket to create a custom look on panel mounts. 

Two-in-One ST5 Connector for Mobile Devices

December 17, 2007 6:28 am | Comments

Japan Aviation Electronics developed the ST5, a low-profile, SIM/microSDTM two-in-one connector for connecting the microSDTM, SDA cards, and GSM11.11 plug-in SIM cards in high-end mobile devices. The connector is 2.8 mm thick, uses a push-push insertion/ejection structure; and has a breaking mechanism to prevent the microSDTM card from disconnecting. The design emits an audible click

Small Linear Motor Pushes Up to 200-times Its Own Weight

December 17, 2007 6:12 am | Comments

New Scale Technologies added to its SQL Series of piezoelectric SQUIGGLE motors, said to be the world’s smallest linear motors. The SQL-1.8 SQUIGGLE motor travels as fast as 7 mm per second and pushes axial loads of up to 30 g -- nearly 200 times its own weight of 0.16 g. At 1.8 × 1.8 × 6 mm, the SQL-1.8 is still less than half the size of competing micro-motors, according to the company.

Phase Lock Loop VCO Covers Wide Frequency Range

December 17, 2007 6:11 am | Comments

Raltron Electronics Corp. released their PCC-A1-3100 PLL family of VCO’s covering a frequency range of between 500 MHz and 3.5 GHz. The unit consists of a PLL IC loop filter and VCO. It uses an internal frequency reference that typically is 10 MHz but could also be specified at different values by the customer. Key specifications for a 3100 MHz unit show typical operating supply voltage at 5.0V at 70 mA

Pump Family Utilizes An Integral Electro-hydraulic Servo Piston Assembly

December 17, 2007 5:45 am | Comments

Sauer-Danfoss announced the release of its H1 45/53cc and 78cc single pumps, joining the 147/165cc single pump and the 45/53cc integral tandem pump for a variety of propel and non-propel applications. The H1 family of closed-circuit variable displacement axial piston pumps is compact and features high power density. All the units use an integral electro-hydraulic servo piston assembly that controls rate (speed) and direction of hydraulic flow.

Short Stoke Pneumatic Cylinders Provide Maintenance-Free Operation

December 17, 2007 5:44 am | Comments

Parker Hannifin Corporation introduced their C05 and C05S Short Stroke Pneumatic Cylinder Series. They feature compact, short stroke cylinders in single- and double-acting versions, suited for clamping and locking operations in a variety of industrial markets. Stainless steel piston rods are standard for corrosion resistance. The double-acting C05 pneumatic cylinder is available in 12, 20, 32, 50 and 63 bore sizes with strokes up to 25 mm.

Quad-Mode Alternative to 604 LED Driver

December 14, 2007 6:05 am | Comments

Catalyst Semiconductor's CAT3604V is a four-channel LED driver eliminates high-profile inductors and unwanted EMI. It has a fourth operational mode, 1.33x, in addition to the typical modes of 1x, 1.5x, and 2x.
