Notes: units use SI conventions. Values labeled “Official spec” are quoted from the current datasheet revision; any “Independent” values would be clearly marked if included.
Where to find official documents & versioning notes
Confirm the correct datasheet revision by checking the file revision code on the document header and matching the part marking on your sample. Common revision changes to monitor include contact plating updates, revised current ratings, and mechanical-tolerance clarifications. Cross-reference any applicable application notes and errata; file names typically include the part number and a revision suffix to avoid confusion.
AK608-2 Pinout & Mechanical Details
Pin-by-pin function table (AK608-2 pinout)
The AK608-2 pinout below presents pin number, signal role, direction, typical voltage/level expectations, and any pull-up/pull-down handling. Reference this table when you map harness wiring or design mating footprints.
| Pin # | Name | Dir | Description | Typical level | Notes |
|---|---|---|---|---|---|
| 1 | V+ | Power | Primary power contact | 0–Vmax (per system) | Rated current; use ferrule or solder termination |
| 2 | GND | Power | Chassis/return | 0 V | Low impedance; tie to ground plane |
| 3 | SIG1 | I/O | Data/signal line | TTL/CMOS levels | Series resistor recommended for EMI |
| 4 | SIG2 | I/O | Secondary signal | TTL/CMOS levels | Consider ESD diodes if exposed |
| 5 | NC | — | No connection / reserved | — | Keep floating or tie per application note |
| 6 | SHIELD | GND | Connector shield | Chassis | Connect via single point to chassis ground |
| 7 | SENSE | I | Optional sense line | Low-voltage | Use pull-down ~100kΩ if unused |
| 8 | KEY | — | Mechanical key / guide | — | Ensure mating orientation |
Callouts: the RESET/ENABLE equivalents for cable assemblies are contact assignments such as SENSE; ensure required external components (decoupling, series resistors, ESD diodes) are placed near the board-side termination.
Package drawings & PCB footprint guidance
Recommended footprint: land pattern should follow the connector’s mechanical drawing with pad-to-pad tolerances of ±0.1 mm. Keepout zones: maintain 0.5–1.0 mm clearance around mating areas. Thermal via suggestion: if high current flows through V+ and GND pads, place 4–8 thermal vias (0.3 mm drill) under large pads and stitch to internal planes. Silkscreen: mark pin-1 and keying clearly.
| Dimension | Value (mm) | Tolerance |
|---|---|---|
| Pin pitch | 2.54 | ±0.05 |
| Overall diameter | 12.0 | ±0.1 |
| Recommended pad | 1.2 × 2.0 | — |
Electrical Ratings & Thermal Limits (AK608-2 ratings)
Absolute maximum ratings & derating guidance
The AK608-2 ratings table lists absolute limits you must not exceed. Absolute maximums are for short events; design with derating margins and calculate junction or contact temperature based on PCB thermal resistance and expected current. Maintain at least 20% margin below absolute ratings for long-term reliability.
| Parameter | Absolute Max | Units |
|---|---|---|
| Voltage withstand | 250 | VAC |
| Contact current (single) | 3.0 | A |
| Storage temperature | -55 to +105 | °C |
| Max junction/contact temp | 125 | °C |
| ESD classification | ≥ 2 kV | HBM |
Derating: convert contact-level dissipation to board temperature rise using measured thermal resistance; for example, each ampere through the contact at measured contact resistance yields I²·R heat—route copper and vias to spread heat to internal planes.
Recommended operating conditions & typical electrical characteristics
Recommended conditions define the range for guaranteed performance: ambient -40 to +85 °C, recommended continuous current ≤2.0 A per contact, and test conditions commonly noted at Ta = 25 °C. Typical contact resistance and insulation values are measured per standard test fixtures; reproduce results using the same clamp and measurement method.
| Parameter | Recommended | Test cond. |
|---|---|---|
| Operating temp | -40 to +85 | Ta |
| Continuous current | ≤2.0 | Per contact |
| Contact resistance (typ) | ≤ 10 | mΩ at 100 mA |
Application Examples & Performance Benchmarks
Benchmarks & independent test summaries
Independent bench tests typically measure power dissipation vs. current and contact temperature rise. A small dataset below illustrates expected behavior under steady-state DC current; replicate test setup with 4-wire resistance measurement, calibrated thermocouple, and controlled ambient.
| Current (A) | Contact voltage drop (mV) | Power (mW) |
|---|---|---|
| 0.5 | 5 | 2.5 |
| 1.0 | 10 | 10 |
| 2.0 | 20 | 40 |
| Ambient (°C) | Max continuous current (A) |
|---|---|
| 25 | 2.0 |
| 60 | 1.6 |
| 85 | 1.2 |
Test setup: decoupled supply, insulated mount, thermocouple on contact face, steady-state after 30 minutes. Known failure modes include contact oxidation under poor mating and elevated contact temperature from excessive continuous current.
Reference application circuits & design examples
Two compact reference layouts: (1) Single-supply power connection with ferrule termination and 0.1 µF decoupling at board entry; BOM: ferrules, 1× connector footprint, 4× thermal vias. (2) Low-noise configuration with series 22 Ω resistor on signal lines, common-mode choke, and TVS on supply line. Layout choices directly affect EMI and measured contact heating.
Integration, Testing & Selection Checklist
Pre-integration checklist & PCB layout tips
- Verify pin mapping against the physical sample; mark orientation on PCB silkscreen.
- Place decoupling at the board-side termination; use low-ESR caps when required.
- Add thermal vias under power pads and stitch to internal copper for current spreading.
- Reserve test points for V+, GND, and one signal per differential pair for in-system validation.
Testing, calibration & compliance tips
- Power-up sequence: apply supply to V+ with current limit, verify GND reference, then assert signals.
- Functional checks: continuity, contact resistance (4-wire), insulation resistance at rated voltage.
- Thermal burn-in: run 2× expected continuous current for 2 hours while monitoring contact temperature; use acceptance criteria tied to max junction/contact temp.
- ESD/EMI screening: perform bench ESD pulses at recommended levels and radiated emissions scans if connector is external.

The AK608-2 datasheet remains the authoritative source for connector specs, and this guide compiles the quick specs, full pinout, absolute AK608-2 ratings, practical benchmarks, and an integration checklist to accelerate your design validation. Engineers should use the datasheet alongside the steps and test setups described here to validate thermal and electrical behavior on their specific PCB.
- Pinout clarity: map pins using the provided table and mark orientation on your silkscreen to avoid wiring errors; verify with a sample before production.
- Critical ratings: observe the AK608-2 ratings for current and voltage and apply a conservative derating margin to account for contact heating and environment.
- Thermal/layout priority: add thermal vias and copper pours under power pads; measure contact temperature under load to ensure compliance.
- Practical tests: run the described functional, thermal burn-in, and ESD checks and document pass/fail criteria before assembly sign-off.
