Product details

What this 4-position header does that a bare pin header won't

Pitch, position count, and the latch that holds the mate

The 1.00mm pitch and single-row 4-position layout demand a tight PCB footprint — the mated stack height is 7.8mm, which gives a low profile for board-to-cable connections in space-constrained enclosures. If you need higher cycle life or a corrosive environment, the NSH series also offers gold-plated variants; check the BM04B-NSHSS-TBT(LF)(SN) peer for a tin-over-nickel alternative.

Sourced per RFQ against your BOM quantity.

The BM04B-NSHSS-TBT sits between the BM03B-NSHSS-TBT (3 positions) and the BM05B-NSHSS-TBT(LF)(SN) (5 positions) in the same NSH series.

Frequently asked questions

Is BM04B-NSHSS-TBT RoHS compliant?

No. The BM04B-NSHSS-TBT is listed as RoHS non-compliant. If your application requires RoHS conformance, use the BM04B-NSHSS-TBT(LF)(SN) peer, which is the lead-free version.
