2-Position 4.2 mm Pitch Header for Wire-to-Board
The 640497-3 is a 2-position, 1-row shrouded header from TE's MR (Miniature Rectangular) series, designed for board-to-cable/wire connections. It mates with the corresponding MR receptacle housing and crimp terminals to form a reliable wire-to-board interconnect. The 0.165" (4.20 mm) pitch is a common spacing for power and signal circuits in industrial and appliance wiring, balancing board density with clearance for moderate currents. Rated 6 A per circuit at 250 VAC, with a temperature range of -55°C to 105°C, this header suits general-purpose applications where a compact, latch-locked connection is needed.
Latch Lock and Shrouded Housing for Vibration Resistance
The latch lock fastening type provides a positive mechanical retention between the header and its mating receptacle, reducing the risk of disconnection under vibration or cable strain — a practical advantage over friction-only headers in field-service or moving equipment. The fully shrouded 4-wall design protects the male pins from accidental shorting or damage during handling and mating, and guides the receptacle into correct alignment.
