http://www.te.com TE Connectivity Switches and Shunts Product News Feed <p>DARMSTADT, Germany -- Jan. 10, 2012 -- TE Connectivity has developed an enhanced generation of electrical circuit breakers for trains which eliminate the disadvantages associated with conventional mechanical, pneumatic circuit breakers. The innovative VESA vacuum circuit breaker (VCB) for electric trains is the world's first all electromagnetically operated system for 25 kV and 15 kV vehicles. After five years of development and design evolution based on field data, the VESA VCB impressively demonstrates what is possible: more than 800 units on four continents are providing the utmost in proven reliability and leading the electric rail vehicle market into a new era. VESA VCB performance has been qualified for high- and medium-speed trains (underground, commuter suburban and freight trains) worldwide and operates successfully in a range of varying weather and climate conditions.</p> http://www.te.com/AboutUs/news/prodnews.asp?ID=1937 Wed, 11 Jan 2012 00:00:00 GMT <p>DARMSTADT, Germany -- Sept. 30, 2011 -- TE Connectivity has introduced a new miniature ALCOSWITCH Blue Series pushbutton switch. Its new internal snap-action mechanism combines compact dimensions with very fast switching and clear tactile and audible feedback indicating that the switch has been properly pressed. Applications cover power and signal. ALCOSWITCH Blue Series pushbutton switches are available in single- or double-pole, double-throw configurations (SPDT, DPDT) with push on/push off or momentary function. The internal contacts are brass with a silver inlay; optional gold plating is available for signal transmission up to 60mA @ 30VDC. The silver inlay contacts have an initial resistance of ≤10 milliohm at 125 VAC, at 1 A at 2 ~ 4 VDC. For the gold plated version the contact resistance is ≤20 milliohm at 100mA at 2~4VDC. Equipped with silver inlay brass contacts, the switches are rated for up to 250 VAC at 1.5 amps for European applications and for up to 125 VAC at 3 amps for North American applications. Due to the extremely fast contact travel, the silver inlay version's life is 25,000 cycles at load, and 50,000 cycles at load for the gold plated version. This compares to the UL requirement of 6,000 cycles at load. The higher lifecycle of the switch means that the lifetime of a valuable piece of equipment is less likely to be limited by its electromechanical control elements.</p> http://www.te.com/AboutUs/news/prodnews.asp?ID=1919 Fri, 30 Sep 2011 00:00:00 GMT
