Product details

It uses the standard 0.100" (2.54mm) pitch on both the mating interface and row spacing, making it footprint-compatible with a wide range of industry-standard receptacles and ribbon-cable IDC connectors. Rated at 5A per contact and 110V, this is a signal-level interconnect — the 5A figure is typical for the pin gauge and contact resistance of a 0.025" square pin, not a power bus. The 30.0µin (0.76µm) gold or Gold, GXT™ plating on the mating surface provides corrosion resistance and supports repeated mating cycles in environments where tin contacts would fret.

Mounting and Orientation

Through-hole right-angle mounting with 0.230" (5.84mm) solder posts. The 0.318" (8.08mm) mating pin length provides a generous wipe length for reliable contact with a standard box or tuning-fork receptacle.

Frequently asked questions

What is the pitch of 86840-170HLF?

The 86840-170HLF uses a 0.100" (2.54mm) pitch on both the mating interface and the row spacing, matching the standard industry footprint for BERGSTIK II and compatible receptacles.

What is the current rating of 86840-170HLF?

Rated 5A per contact at 110V. This is a signal-level rating for the 0.025" square pin — suitable for logic-level and low-power interconnects, not a power bus.

Is 86840-170HLF shrouded or unshrouded?

Unshrouded — the pins are exposed with no plastic shroud. This allows access for probing or manual wiring but lacks the polarization and pin protection of a shrouded header.
