Matching a sensor interface with a programmable logic converter or controller hardware that can accept only one type of input—npn or pnp—can be difficult. The last-stage modification circuit described ...

AutomationDirect has added the new AchieVe series of inductive proximity sensors. These tubular inductive proximity sensors made from stainless steel are offered in 8 mm, 12 mm and 18 mm barrel sizes.

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...
