Product details

Board-to-wire header for compact SMT designs

Its surface-mount right-angle orientation and shrouded 3-wall housing make it a space-efficient choice for routing signals or low-voltage power in automotive, industrial, and medical equipment.

Pitch and footprint constraints for layout

The 0.047" (1.20 mm) pitch drives the PCB footprint density.

Mating and locking for vibration resistance

The friction lock fastening type secures the mating half without a secondary latch, suitable for environments with moderate vibration. The 3-wall shroud guides the mating connector and protects the rectangular tab contacts from stubbing.

Frequently asked questions
