What the 2.50mm Pitch and 3A Rating Mean for Your Layout
The S2B-EH(LF)(SN): The latch lock fastening type provides positive retention against moderate vibration — the mating receptacle clicks into place and stays until deliberately released.
This header mates with JST EH series crimp receptacles (e.g., EHR-2) using the matching tin-plated male pins — the latch lock engages with the receptacle housing for a vibration-resistant connection. Termination is press-fit, solder — the through-hole posts (0.126" / 3.20mm long) are soldered to the PCB; the press-fit feature provides initial retention during wave or hand soldering.
