Wireless switches from Deak Technologies , E-T-A Circuit Breakers , and Samtec high-speed connectors are among recently introduced new products. In addition, links are included to recent coverage from Control Engineering and other Reed Business Information resources, including information about IMTS, RFID, and power supplies.

E-T-A’s 4140 circuit breaker is rugged and provides high current-carrying capacity with minimum weight.

Deak Technologies Inc . designed a no-battery, wireless electrical power wall switch expected to save 50-70% of the material and labor cost associated with electrical wiring installations; it can be used worldwide without conversion issues. Energy generated from the switch can be used to power other forms of wireless communication protocols as well, the company said. Deak also offers (through Clark Solutions ) a new form of solid-state pump using a piezoelectric wafer 0.007-in. thick to cause pumping action by resonant acoustic (sound) waves. Deak expects the pump will find worldwide use in cooling electronic circuitry such as computers and laser systems.

Samtec’s Q2 is available with up to 160 I/O points per connector set in a single-ended configuration and up to 64 pairs in a differential pair configuration.

E-T-A Circuit Breakers announced the 4140, a temperature-compensated circuit breaker with curent ratings up to 50 A in a package smaller than Mil Spec MS 24571 and 10% lighter than most competing devices. With this addition to E-T-A's high-performance circuit breaker line, design engineers can select an E-T-A circuit breaker for any rating from 1 to 50 A.

Connectors: Samtec ’s Q2 second-generation high-speed connector system (QMSS/QFSS Series) options have been expanded with power pin options, positive alignment features, edgemount designs, and single-ended and differential pair signal routing. EMI shielding is now optional for applications that require increased insertion depth and other rugged features this system offers without grounded side shields.
