£2.45
The TE Connectivity 1SNA168949R1700, supplied under the FEHD2 designation and also referenced as PLAEXT, is a beige end section designed for compatible ENTRELEC SNA HD quick-connect terminal blocks. Installed at the side of the appropriate terminal assembly, it provides the insulating closure required at the end of the terminal row.
The FEHD2 is specifically associated with compatible HD2.5/6 series terminal blocks used in industrial and railway electrical applications. Its 1 mm nominal thickness allows the terminal row to be closed with minimal additional panel width while maintaining a purpose-designed insulating barrier.
Manufactured from polyamide in a beige finish, the 1SNA168949R1700 measures approximately 40 mm high × 1.2 mm wide × 46 mm long. The manufacturer railway catalogue lists a unit weight of approximately 2 g and a pack quantity of 20.
End sections are used where the side of a modular terminal block requires an insulating closure. Selecting the correct end section helps maintain the intended physical separation within the terminal assembly while providing a neat and complete installation on the mounting rail.
The TE Connectivity FEHD2 is designed specifically for compatible ENTRELEC SNA HD2.5/6 quick-connect terminal blocks. Its compact polyamide construction and snap-on format make the 1SNA168949R1700 a practical accessory for terminal rows used in control, signalling, transportation and industrial electrical systems.
