Backplane signal header — 48 positions, press-fit, gold contacts
The TE Connectivity 536504-2 is a 48-position Futurebus-style header from the Z-PACK series, arranged in 4 rows at a 2.00 mm pitch. This is a signal-level backplane interconnect — the 30 V rating confirms it carries logic and data lines, not bus-level power. The press-fit termination eliminates soldering, making it suitable for solderless backplane assembly where rework and field-replacement of individual pins matter. The UL94 V-0 rated natural housing and -55°C to 125°C operating range suit it for enclosed equipment in uncontrolled environments.
What the press-fit termination means for your assembly
Press-fit (compliant pin) termination means the header is pressed into plated through-holes on the backplane — no solder wicking, no wave solder defects, and the pin's interference fit holds it mechanically. This is standard for high-reliability backplanes where thermal cycling and vibration are concerns. The through-hole mounting type allows the compliant pin to engage the PCB barrel directly.
