VFS 60 blind hollow shaft encoders from Sick Stegmann, Inc. feature a unique nickel code disc that provides robust operation in harsh industrial environments, and tolerance to temperatures as high as 100ºC. They are IP65 rated and deliver from 1ppr to 10,000 ppr in an industry-standard 60 mm housing. The ball bearings that support the encoder shaft are spaced 30 mm apart for excellent concentricity (± 0.3/± 0.1 mm radial; ± 0.5/±0.2 mm axial) and robustness, and minimum encoder vibration
Presented as the first such single-chip devices on the market to integrate high-voltage (75-V) half-bridge MOSFET drivers with a 1.6-A peak current driving capability, the Vishay Siliconix SiP11205 and SiP11206 controllers are designed to work on the primary side of an isolated half-bridge intermediate-bus converter in telecom and network equipment and in 1/16-brick or 1/8-brick power modules. Providing current monitoring and control features, the self-driven synchronous-rectification controllers step down voltages with greater than 95 % efficiency with an input voltage range from 36V to 75V
Phoenix Contact’s VALVETRAB-SQ surge protective devices (SPD) offer safe, reliable surge protection from 40,000A to 200,000A. The NEMA-style product series includes approximately 50 part numbers in three different mountable designs designated by CC (control cabinet), SP (sub-panel), and SE (service entrance) identifiers. The VAL-SQ CC Series offers an economical method of
In the area of medical switch components, current trends continue to call for further miniaturization to meet the needs of space-saving applications like hearing aids.
Providing engineers the ability to create Ultra-Low Power (ULP) ISM-band button-cell powered wireless links, a family of reference designs using Nordic Semiconductor RF tranceiver chips require only a digital In/Out, power (+V) and ground (GND) connection for implementation. The seven module designs are based on the 2.4GHz nRF24L01 (RF Digital Modules RFD21010, RFD21676, RFD21677), nRF2401 (RFD21006), and nRF24E1 (RFD21018) and the 433/868/915MHz nRF905 (RFD21002), and nRF9E5 (RFD21014).
Sensoray introduced a 1080i compatible HDTV image processor for embedded systems in the broadcast and medical markets. The Model 2246 captures an HDTV signal from an HD or SD-SDI source and formats it for display and image compression. Conventional analog video inputs are also accepted. Its high speed hardware can scale and add text/graphics prior to compression, display and storage. A scan converter section formats
The CTBDD93 series feature high quality rising clamp wire connections and are UL, cUL, CE, VDE and IMQ approved. They available in two standard pitches of 5 mm and 5.08 mm, and are ordered as separate male and female connectors. The two connectors can be mounted vertically, or at 90°, to suit different applications. The double level design of the male connector reduces the required space on the PCB by a half. The terminal blocks are molded in green UL94 V-0 flame retardant PA66, and are
The Automotive Sensors division of PCB Piezotronics announced a high-temperature preamplifier, designed to overcome high temperature testing challenges associated with NVH powertrain and vehicle underhood testing applications. The Model HT426E01 is a 1/2” preamplifier operating from ICP sensor power, terminating with a BNC connector and utilizing standard coaxial cables. The model also features a low attenuation factor
GE Global Research announced the successful demonstration of “roll-to-roll” manufactured OLEDs. The company claims that this process is a key step toward lower costs of the technology.
