ELECTRONICS: Carling Technologies’ N-Series Addressable Switch offers the look and feel of a traditional electromechanical control coupled with a built-in PCB to provide customers with a flexible, cost-effective alternative to a CAN/LIN-based switch. The N-Series produces up to 144 individual switch IDs by using a resistive ladder circuit. Different switch IDs are achieved by changing the resistor values tied to individual loads. The individual loads can then be assigned to the specific functions the switch is controlling. Each switch is connected to an ECU and the application software is written to recognize the switch IDs to determine which load is being controlled, as well as the selected actuator position. The end result means that wiring harnesses are more simplified and specific loads can now be controlled from any location within a vehicle cab. Switch locations can now be rearranged without the need for a costly and time-consuming harness redesign, giving designers the ultimate in design flexibility. The N-Series has a contact rating of 4VA at 28V dc (max); dielectric strength of 1,250V RMS between pole to pole; and 3,750V RMS between live parts and accessible surfaces. Insulation resistance is 50 Megaohms and contact bounce is 20 msec max. It has an operating temperature of -40 to 85C.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
Two issues have been the bane of the plastics industry for as long as one can remember: The ban on plastic grocery bags and whether the use of bisphenol A (BPA) in plastics such as polycarbonate and PVC is harmful to humans.
One expects to see outlandish apparel at major global fashion events, but New York Fashion Week may have outdone itself, and set a new bar for Paris and Milan, when it put an Ebola jumpsuit in the spotlight.
