### 2. Technical Specifications
The assembly consists of two different termination styles on a flat ribbon cable:
#### A. Connector A: Socket (IDC)
* **Type:** 3M Wire-to-Board IDC Socket.
* **Pitch:** 0.100" (2.54 mm).
* **Features:** Often includes a "Pull Tab" (indicated by the 'C' or 'D' in some configurations) for easy disconnection without straining the wires.
* **Strain Relief:** Usually equipped with a plastic strain relief clip to protect the IDC gas-tight connection.
#### B. Connector B: PCB Transition
* **Type:** Permanent solder-mount connector.
* **Function:** This end is soldered directly into the PCB holes, eliminating the need for a second header and reducing costs/profile height.
* **Pitch:** 0.100" (2.54 mm).
#### C. Cable Properties
* **Wire Gauge:** 28 AWG Stranded.
* **Insulation:** PVC.
* **Voltage Rating:** 300V.
* **Temperature Rating:** 105°C.
