Key Features
- 2-position polarized and shrouded rectangular power connector prevents reversed power wiring during field assembly or maintenance
- Matte tin over 50 µin nickel contact finish delivers low contact resistance and corrosion resistance for reliable power connections
- Straight PTH (through-hole) mounting provides maximum mechanical retention strength on PCBs subject to cable pull forces
- Copper alloy contacts accommodate high-current power wiring typical of 5 V to 48 V DC distribution rails
- Male contact gender mates with SAMTEC IPBS series cable-side female housings for quick-disconnect power connections
Applications
The IPBT-102-H1-T-S-K is used as a board-mounted power inlet connector in embedded computer systems, industrial control modules, and benchtop power supplies where a 2-pin keyed header provides a secure and polarized DC power input point. Its through-hole mounting ensures strong mechanical retention when an attached power cable is subjected to repeated plug/unplug cycles or incidental pull forces during equipment servicing. The shrouded polarization also makes it suitable for consumer electronics and IoT gateway devices where user-accessible power ports must be foolproof to prevent damage from reversed power connections.

Frequently Asked Questions
What contact finish does the IPBT-102-H1-T-S-K use, and how does it affect long-term connection reliability?
The IPBT-102-H1-T-S-K contacts are plated with matte tin over a 50 µin nickel barrier layer. The nickel barrier prevents tin from diffusing into the copper alloy base, which would cause high-resistance intermetallic compounds over time. Matte tin provides a soft, solderable surface that forms a gas-tight connection under the normal mating forces of the shrouded housing, maintaining contact resistance below 20 mΩ across thousands of mating cycles and over the full operating temperature range typical of industrial environments.
For a 12 V, 5 A DC power rail on an embedded SBC, is the IPBT-102-H1-T-S-K rated for this current level?
SAMTEC's IPBT series rectangular power connectors are rated for 5 A to 7 A per contact depending on contact pitch and wire gauge. With 2 contacts available in the IPBT-102, parallel wiring of both pins for a single power supply allows up to 10 A to 14 A total current capacity, well above the 5 A requirement for a 12 V SBC rail. Using both pins in parallel reduces contact resistance and keeps each contact's self-heating within the rated temperature rise, typically less than 30°C above ambient at rated current.
How does the polarized shroud on IPBT-102-H1-T-S-K protect against accidental reverse-polarity power connection?
The asymmetric shroud geometry of the IPBT-102-H1-T-S-K allows the mating cable-side female connector to insert in only one orientation. An incorrect polarity insertion attempt causes the housing to mechanically block insertion before any contact is made, preventing reverse voltage damage to the connected PCB. This is especially important in field-serviced equipment where technicians may swap power cables; the keying ensures even an untrained operator cannot apply -12 V instead of +12 V to a 3.3 V logic board, which would destroy components in milliseconds.
What is the typical PCB mounting style of IPBT-102-H1-T-S-K, and how does through-hole compare to SMT for a power connector?
The IPBT-102-H1-T-S-K uses straight through-hole (PTH) mounting, with pins that pass through the PCB and are soldered on the underside. Through-hole mounting provides solder joint shear strength of approximately 10 N to 20 N per pin—significantly higher than the 3 N to 8 N typical of SMT gull-wing or J-lead power connector pads—because the solder fills the via barrel and bonds to the full pin length. This added mechanical retention is critical when a power cable exerts lateral or pull forces on the connector during mating cycles, which would otherwise lift SMT pads off the PCB surface over time.
