The E56 pancake sensor from EATON electrical sector is a high performance inductive proximity sensor. The E56 pancake provides greater sensing ranges than other inductive sensor package types. The E56 pancake family provides convenience and ease of wiring with auto-configurable, complementary outputs. (auto-configurable outputs automatically detect an NPN or PNP output configuration and switch the sensor accordingly, without user intervention). Power and output LEDs make troubleshooting much easier than conventional proximity sensors, which usually only feature output LEDs. These convenience features, combined with the performance of the E56 pancake, make It an excellent inductive sensing solution for applications requiring an extremely rugged, long range sensing solution.
