Datasheet

Lumberg is expanding its product range with the 3517-4 RAST 2.5 connector model. When it comes to direct RAST connectors with a contact pitch of 2.5mm, automotive industry demand for better retaining forces and locking on the PCB edge is growing. With Lumberg already grading its products by retaining force, the 3517-4, with optional keying rib and closed sides, reaches an outstanding retaining force of equal to or more than 13.4N.

This is made possible by the reinforced locking toes inside the reliable geometry of the casing, which ensure a higher mechanical retention on the PCB without taking up additional casing space.

This model from the RAST 2.5 connector range with a proven track record for cars can also mate with existing harnessing machines with single wires of a diameter ranging between 0.22 and 0.38mm² and insulation resistance of up to a max. 1.6mm.

Suitable for application in temperatures between -40 to +130°C and with a rated voltage of 32VAC, the additional direct connector version shows its diversity and convenience of use with small load currents of up to 4A (T_amb 60° C). The connector comes with 2 to 9 poles and two different materials for the insulating body. Next to PBT GV of V0 flammability standard according to UL 94, there is also a glow wire resistant version (GWT 750° C) in PA of a V2 flammability rating according to UL 94. Both carry tin-plated contact springs made of bronze.
