ZIPport(TM) panel interface connectors mount on outside of electrical control panel boxes and act as pass-through connections, allowing operator to interface with PLCs and other programmable devices without opening control box. Units include standard reset 3 A circuit breaker and are available with single/duplex/GFCI power outlets as well as no-power option. Designed for frame sizes 6-48, communications connectors available include D-sub, RJ45, RJ12, USB, Ethernet, and Data Highway.
Dust and water protected, IP67 rated XX-HD Series includes 3-pole female XLR connector (NC3FXX-HD-D) with optional black housing (NC3FXX-HD-B-D) as well as 3-pole male XLR connector (NC3MXX-HD-D) with optional black housing (NC3MXX-HD-B-D). Rubber sealing jacket protects against mechanical shock, while chuck type strain relief system helps in secure clamping of cables. Product features rugged zinc die cast shell and gold contacts.
Sealed to IP67 for protection from dust and water immersion, TL52 series tactile switch has mechanical life of 100,000 cycles, min. It has contact rating of 50 mA at 12 Vdc, contact resistance of 100 m<font face='Symbol'>W</font> (initial max), insulation resistance of 100 M<font face='Symbol'>W</font> (min at 100 Vdc), and dielectric strength of 250 Vac. With operating temperature between -25°C and +85°C, product has force of 260 ±50 gf and 160 ±50 gf, and travel distance of 0.3 +0.2/-0.1 mm.
Offering MTBF of 3.5 million hr, M1WB series feature 1 kVdc of isolation and fixed input with unregulated outputs. They come in SIP, DIP, and SMD packages with industry standard pinouts and operate over -40 to +85°C range. Delivering efficiencies up to 81%, RoHS-compliant products do not require any heat sink or external components. They are designed for applications where single power supply is isolated from input power supply in distributed power supply system on circuit board.
Low Profile Cable Ties feature low head height and, when cut, stub is concealed within head to create smooth, snag-proof outer surface that conforms to bundle. They are available in UV-resistant black and natural nylon, and can be installed using industry standard tools. UL/CSA listed, QPL approved, ties come in 7-16 in. sizes in medium and heavy duty styles, and are suited for wire harnesses and bundling of tubing and hoses.
Designed for low-pressure water immersion or fording applications, KJAYA Series provides hermetic sealing of 0.01 micron cu-ft/hr for pressure differentials of 15 psi. It is available in sizes 9-25 in wall and jam-nut mounting receptacles and is water immersion sealed to 10<sup>-7</sup> cm³/sec. Meeting all MIL-STD-810 and IP67 water immersion requirements, connector is suited for variety of applications including integrated avionics, radar, electronic warfare systems.
Optimized for light transmission with minimal heat generation, expandable and waterproof gLux(TM) features modular and adjustable light banks that let users fill incubator with general or direct lighting of various intensities. This energy-efficient, high-output lighting system comes standard in 10 and 25 ft³ Diurnal Incubators or is available as accessory for all other 10 and 25 ft³ products as accessory number LGHT301 or LGHT303.
Suited for dual camera applications, FSA1211 is 12-port, SPST analog switch that isolates high speed bus from parasitic components to maintain signal integrity. It has bandwidth of 720 MHz, high ESD of 5.5 kV, and offers optimal way to isolate capacitance and maintain signal integrity for high speed data paths. When isolating unused parallel interface, switch reduces radiated EMI of path, improving RF desense.
Offering look and feel of electromechanical control coupled with built-in PCB, N-Series produces up to 144 individual switch IDs by using resistive ladder circuit and enables individual loads to be assigned to specific functions. Application software determines which load is being controlled as well as selected actuator position. While simplifying wiring harnesses, switch also enables specific loads to be controlled from any location within vehicle cab.
Utilizing Gallium Arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) technology, symmetric SPDT switches operate in multiple market segments, including cellular infrastructure, WiFi, WiMAX, and antenna tuning applications for mobile devices. Models RF3021 and RF3025 are housed in 16-pin 3 x 3 mm QFN package and feature high isolation and single-bit control. Offered in 6-lead SC70 package, RF3023 and RF3024 feature low insertion loss and moderate isolation.

IEC 61439 - The New Switchgear Standard
The new standard IEC 61439 replaces the old 60439. After a first reading my initial impressions are that it is a more clearly defined standard. Some key differences are that the distinction between type tested assemblies (TTA) and partially type tested (PTTA) is gone, verifying the performance is addressed in new ways and the specification of current ratings is updated. What I found particularly interesting is the clarifications on the specification of current ratings.
Nikola Tesla
Nikola Tesla was born exactly at midnight on July 10, 1856 in the tiny village of Smiljan, Lika in Croatia. In his late teens, Tesla left the village to pursue a career in electrical engineering. He started attending the Austrian Polytechnic in Graz, but never graduated and cut off all ties with his friends and family shortly after the start of his third year. He disappeared for awhile and suffered a nervous breakdown before being found and convinced by his father to attend Charles-Ferdinand University in Prague. However, he stayed for only one term, leaving after his father died.
