The fully shrouded 4-wall housing protects the contacts from accidental shorting and guides the mating plug into alignment. Insulation height is 0.248\" (6.30 mm), giving clearance for the locking latch. ## Through-hole right-angle termination Contact length after the post is 0.134\" (3.40 mm). The header is through-hole mounted, right-angle, so the mated wire exits parallel to the board. This saves vertical space in shallow enclosures compared to a vertical header. Housing material is glass-filled PA66 with UL94 V-0 flammability rating, acceptable for equipment inside an enclosure.","metaTitle":"JST S04B-ZESK-2D Header – 4 Pos, 1.5 mm Pitch, Right Angle","metaDescription":"JST ZE series 4-position shrouded header, 1.50 mm pitch, 2 A, 100 V, through-hole right-angle, locking ramp.
