The 4.20 mm pitch gives you room to route traces between pads on a standard FR-4 board without necking down to sub-0.25 mm track widths, even at 2 oz copper. Board lock features press into the PCB during through-hole soldering, anchoring the header so the solder joint doesn't take the full shear load from the mated cable assembly. In a lighting fixture or conveyor control panel, that extra retention keeps the connector seated when the cable gets snagged during maintenance. ## What Mates With This Header and How to Terminate The mating half is a VAL-U-LOK receptacle housing (e.g., 2029172-2 or similar 4-position cavity) that accepts 20-24 AWG crimp terminals. The square pin shape (0.64 mm typical) gives good solder wetting and a solid mechanical anchor. ## Current Rating and Thermal Derating in the Enclosure The 600 VAC rating is a creepage-and-clearance limit for the 4.20 mm pitch and housing material — in a pollution degree 2 environment, you can run 480 VAC line-to-line without worrying about tracking across the insulator surface. ## Active Production — No Obsolescence Worry","metaTitle":"2029172-4 TE VAL-U-LOK Header 4-Pin 4.20mm Pitch 9A Board","metaDescription":"2029172-4 TE Connectivity VAL-U-LOK header, 4 positions, 4.20mm pitch, 9A rating, shrouded with locking ramp and board lock.
