SL-156 Connectors with TPA Device

TE Connectivity's (TE) SL-156 Connectors with Terminal Position Assurance (TPA) Device feature single-row connectors with a 0.156'' (3.96mm) contact pitch. These connectors are rated up to 250V_AC for voltage handling with current-carrying capabilities up to 10A. The housing design prevents the terminal from being inserted upside down because the cavity can only be loaded in one way, and polarization tabs ensure the housing and header are mated correctly. Breakaway style retainers with the TPA device secure the contacts in the housing. TE SL-156 connectors are fully compatible with SL-156 and MTA-156 board headers, available with 2 to 12 positions, and can be used as a drop-in replacement with existing headers.
