Product details

Its 0.059" (1.50 mm) pitch and right-angle orientation make it a compact choice for control panels, sensor interfaces, and low-power signal distribution inside an enclosure.

Locking ramp and board guide keep the connection secure

A locking ramp fastening type means the mating receptacle clicks into place and resists vibration-induced disconnection. 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.

Frequently asked questions

Where can I buy JST S04B-ZESK-2D and how is it quoted?

The S04B-ZESK-2D is an active JST part. No on-shelf stock is held; submit an RFQ for current pricing and lead time. The datasheet is available from JST or through the product page download link.

Is S04B-ZESK-2D RoHS compliant?

No. This header is listed as RoHS non-compliant. For a RoHS-compliant alternative in the same ZE series, consider the S06B-ZESK-2D(T)(LF)(SN) (6-position) or other (LF)(SN) suffix variants.

What mates with the S04B-ZESK-2D header?

It mates with a ZE series crimp receptacle housing (sold separately). The locking ramp on the header engages with the latch on the receptacle. Confirm the mating half part number with your JST distributor.
