CONSHARE's 0.80mm floating BTB male header is engineered for mid-density board-to-board interconnection where alignment tolerance and long-term reliability matter. Built with an LCP housing, gold-plated copper alloy contacts, and an integrated floating mechanism that compensates up to ±0.30mm of positional error, this connector doesn't just fit your board—it protects your design from the realities of SMT assembly, thermal cycling, and mechanical stress.

Most BTB connectors treat misalignment as an assembly problem to be solved with tighter tolerances. We think that's the wrong approach. Alignment error is statistically inevitable—and trying to eliminate it entirely just drives up cost. CONSHARE's floating design absorbs it instead.
The integrated floating element shifts in both X and Y axes to absorb pick-and-place drift, PCB fabrication variances, reflow-induced shifting, and even board warpage. The result: higher first-pass yield, less solder joint fatigue, and a connector that's forgiving in real-world manufacturing conditions.
3µ" of gold plating isn't a marketing number—it's the sweet spot between cost and reliability. Gold doesn't oxidize, doesn't corrode, and maintains consistent contact resistance through mating cycles and environmental exposure. Pair that with a nickel underlayer for diffusion barrier protection, and you get a contact system that stays reliable for the life of your product.
Liquid Crystal Polymer isn't the cheapest housing material, but it's the right one for SMT connectors. LCP maintains exceptional dimensional stability through multiple reflow cycles, absorbs minimal moisture (reducing popcorning risk), and delivers the mechanical strength needed for a 0.80mm pitch form factor without thick, space-wasting walls.
CONSHARE offers this male header across five standard configurations covering the most common pin count and stack height combinations.
Pin Count | Housing Height | Mating Height | Typical Application Profile |
|---|---|---|---|
40 (2×20) | 7.80mm | 9.00mm | Compact designs needing moderate I/O with airflow clearance |
60 (2×30) | 6.80mm | 8.00mm | Low-profile applications with mid-range signal requirements |
60 (2×30) | 7.80mm | 9.00mm | Mid-density I/O where board spacing and thermal management matter |
80 (2×40) | 6.80mm | 8.00mm | High-signal, low-profile designs with tight mechanical constraints |
80 (2×40) | 7.80mm | 9.00mm | Maximum signal density with extra clearance for taller components |
Need a different configuration? We support custom pin counts, plating options, and housing variations. Contact our engineering team to discuss your requirements.
PLCs, I/O modules, and industrial controllers operate in environments with temperature swings, vibration, and long service life expectations. The floating design absorbs mechanical stress, while the gold contacts and LCP housing handle extended temperature ranges reliably.
Line cards, switch modules, and optical transport units demand high-density interconnection with consistent signal integrity. The 0.80mm pitch strikes the right balance between density and manufacturability—and the floating mechanism adds reliability for equipment that sees multiple service insertions.
Diagnostic and monitoring equipment requires connectors that perform consistently under temperature control and withstand periodic cleaning protocols. The LCP housing's chemical resistance and gold contacts' corrosion resistance make this header a solid choice for medical applications.
Compact IoT gateways and edge computing devices need high I/O density in limited space. The 40-pin low-profile configuration fits where space is at a premium, while the floating design compensates for PCB warpage common in thinner, cost-optimized boards.
A: The design compensates up to ±0.30mm in both X and Y directions. This covers typical SMT placement tolerances, PCB dimensional variances, and even minor board warping. For most production scenarios, this is more than enough headroom.
A: For most industrial, telecom, and consumer applications, 3µ" gold provides excellent corrosion resistance and contact stability through normal mating cycles. If your product requires very high mating cycle counts or operates in extremely harsh environments, we can discuss thicker plating options.
A: The 0.80mm pitch and contact geometry work well for typical mid-speed interfaces—control signals, sensor data, and multi-megabit serial communication. For multi-gigabit high-speed designs, you'll want a connector specifically optimized for impedance control and signal integrity. Our team can help you evaluate if this connector fits your data rate requirements.
A: We provide detailed PCB footprint recommendations with every part number, including recommended pad dimensions, solder mask openings, and keep-out areas. The technical drawing includes a top-side PCB layout reference to guide your board design.
A: Yes, we offer corresponding female headers in matching pin counts and stack heights for a complete mated pair solution. We recommend sourcing both male and female from CONSHARE to ensure proper engagement depth and mechanical compatibility.
Quality you can count on at volume. Every connector we ship passes in-process dimensional checks, plating thickness monitoring, and 100% contact resistance testing. Our ISO 9001-certified manufacturing processes are built for consistency—not just for samples, but for the 100,000th unit off the line.
Engineering support that actually helps. We don't just ship parts and disappear. Our application engineering team can help with footprint optimization, reflow profile guidance, mating partner selection, and custom configuration development. We're here to make sure your design works the first time.
