Power Triple Lock Connector System

TE Connectivity's (TE) Power Triple Lock (PTL) Connector System offers three locking methods and an enhanced design to meet the market demand for improved connector stability and reliability in power and signal applications. An audible 'lock' latch provides confirmation when the cap and plug are mated while the ribs surrounding the latch prevent wires from becoming snagged underneath the latch. Optional Connector Position Assurance (CPA) ensures the PTL Connector System is not accidentally disengaged. The optional Terminal Position Assurance (TPA) feature ensures contacts are fully seated in the housing and provides an added measure against contact backout. Additional features include high temperature housings up to 150°C (302°F) and an upgraded lanceless contact design.
