Product details

12-Position SUR Header for Board-to-Cable Interconnects

The BM12B-SURS-TF(LF)(SN): The 0.80mm pitch and surface-mount termination suit it for compact, low-profile PCB layouts where the mating cable assembly plugs in from above.

The insulation height of 2.70mm leaves clearance for the receptacle's latch and wire exit. The header is loaded with all 12 positions; no empty cavities.

The SUR series offers the same 0.80mm pitch and 3.95mm stack height in 8-position (BM08B-SURS-TF) and 10-position (BM10B-SURS-TF(LF)(SN)) variants.

Frequently asked questions

Does BM12B-SURS-TF(LF)(SN) mate with JST SUR crimp housings?

Yes, this header is designed to mate with JST SUR series crimp-style receptacle housings. The push-pull fastening type and 0.80mm pitch align with the SUR receptacle contact layout.

What is the closest alternative to BM12B-SURS-TF(LF)(SN)?

The BM12B-SURS-TF is the same part without the (LF)(SN) suffix — identical specs and position count. For fewer circuits, the 10-position BM10B-SURS-TF(LF)(SN) and 8-position BM08B-SURS-TF share the same pitch and stack height.
