The 4-1473562-4 is a 4-way 1-row Rectangular Plug Assembly with gold-plated copper alloy contacts and green PVC/PE/PTFE housing. The e-CON standard was developed in Japan in 2001 by a group of Japanese manufacturers in order to standardize connections from sensors to terminals. This standard is not under control of any standard organizations. Without the standard, each manufacturer had specified different connectors for terminations of sensors to programmable logic controllers (PLCs) and end users had to prepare many different connectors and different tools. In order to improve this situation and create a user-friendly environment, Tyco Electronics has offered AMP remote input/output terminal system (RITS) connectors as the standard interface connector for sensors and the 4-position RITS connector is approved as the industry standard connector.
