XKC-Y25-V (High and Low Level Output) XKC-Y25-NPN (NPN Output) XKC-Y25-PNP (PNP Output) XKC-Y25-RS485 (RS485 Output) The XKC-Y25-XXX non-contact liquid level sensors are primarily designed for ...

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.

ISSCC: on-chip temperature sensors Two papers at the International Solid-state Circuits Conference tackled ultra-low power on-chip temperature sensing, one using an npn transistor and the other by ...
