Key Features
- Polarized shrouded rectangular power connector body prevents reverse mating, protecting power distribution circuits from incorrect insertion
- Matte tin over nickel contact finish on copper alloy contacts provides low-resistance connections rated for continuous power currents up to 3 A per contact
- Dual-row 4-position 0.100 inch pitch layout delivers high current density in a compact PCB footprint for power distribution boards
- Keyed design (K option) provides additional mechanical anti-mismating protection beyond shroud polarization for safety-critical power connections
Applications
IPBT-102-H2-T-S-K is used in power distribution boards, industrial motor controllers, and embedded system backplanes where reliable keyed, polarized power connector mating is required across 4 positions at 0.100 inch pitch. The matte tin over nickel contact finish and copper alloy construction support continuous current loads in 5 V, 12 V, and 24 V power rail applications, minimizing contact resistance in high-cycle-count mating environments. The shrouded and keyed design makes it suitable for field-serviceable equipment where technicians must frequently disconnect and reconnect power harnesses without risk of reverse connection.

Frequently Asked Questions
How does the keyed (K) design of IPBT-102-H2-T-S-K prevent reverse power connection on a 24 V industrial bus?
The keyed (K) option adds a mechanical polarization feature to the IPBT-102-H2-T-S-K's shroud that physically prevents the mating connector from being inserted in the wrong orientation. On a 24 V industrial power bus, reversing the connector would connect the 24 V supply directly to the GND pin, potentially damaging downstream electronics. The keying feature ensures that only connectors with matching key orientation can mate, providing a hard mechanical barrier against reverse connection across all 4 positions at 0.100 inch pitch, even in low-visibility or high-stress maintenance environments.
What current capacity can the IPBT-102-H2-T-S-K deliver per contact in a 12 V power distribution application?
SAMTEC IPBT series rectangular power connectors with matte tin over nickel contacts on copper alloy are rated for up to 3 A per contact in free-air conditions at 25°C ambient. For a 4-position IPBT-102-H2-T-S-K used in a 12 V power rail, the 4 contacts can collectively distribute up to 12 A total if load is shared equally, or a single pair of contacts can carry 6 A for a dual-contact power and return configuration. Derating to 70% at 70°C ambient reduces per-contact capacity to approximately 2.1 A, which is still adequate for most embedded system 12 V auxiliary power feeds.
For a motor controller PCB undergoing frequent maintenance, what advantage does the shrouded design of IPBT-102-H2-T-S-K offer over open-frame connectors?
On a motor controller PCB requiring quarterly maintenance access, an open-frame 0.100 inch pitch connector exposes all 4 contacts to accidental tool contact and allows the cable connector to be inserted at any angle, risking bent pins or mis-mating. The IPBT-102-H2-T-S-K's polarized shroud guides the mating connector to the correct position with a single motion, protecting the 4 male contacts from lateral tool damage. The shroud also provides a finger-safe guard over the live contacts, reducing the risk of incidental short circuits during maintenance when 24 V power remains energized on adjacent rails.
How does matte tin over nickel plating on the IPBT-102-H2-T-S-K contacts perform in a high-cycle-count connector application?
Matte tin over nickel plating on the copper alloy contacts of IPBT-102-H2-T-S-K provides a solderable, low-resistance surface with contact resistance typically below 10 mΩ in initial mating. The nickel underplate acts as a diffusion barrier, preventing tin migration into the copper alloy base and maintaining contact integrity across 30 to 50 mating cycles typical of field-service connectors. For applications requiring more than 100 mating cycles, gold-flash over nickel is preferred, but for power distribution connectors mated 10 to 30 times over a product lifetime, matte tin over nickel offers a cost-effective solution that maintains rated 3 A per contact performance.
