The part number **M3SMS-Z-R** refers to a high-quality connector assembly manufactured by **3M**. This specific component is a 2.00mm pitch Ribbon Cable Assembly, typically used for board-to-board or device-to-board internal connections. --- ### Technical Specifications The following table outlines the key electrical and physical characteristics of the M3SMS-Z-R series: | Feature | Specification | | :--- | :--- | | **Manufacturer** | 3M | | **Connector Type** | Socket to Card Edge | | **Number of Positions** | Varies (Standard 10, 14, 16, 20, 26, 34, 40, 50) | | **Pitch (Connector)** | 2.00mm (0.079") | | **Cable Type** | Flat Ribbon Cable (Gray or Rainbow) | | **Contact Finish** | Gold or Gold Flash | | **Mounting Type** | Free Hanging (In-Line) | | **Current Rating** | ~1A per contact | --- ### Key Components & Construction #### 1. The Socket (M-Side) The "M" in the prefix usually denotes the molded socket. These sockets are designed to mate with standard 2.00mm headers. They often feature: * **Polarization bumps:** To ensure the cable is not plugged in backward. * **Strain relief:** A plastic clip that prevents the wires from pulling out of the IDC (Insulation Displacement Connector) contacts. #### 2. The Card Edge (S-Side) The "S" transition often refers to the termination style or the specific card-edge interface. This allows the ribbon cable to slide directly onto the gold fingers of a printed circuit board (PCB), eliminating the need for a mating header on the target board. #### 3. Ribbon Cable The assembly uses high-flexibility stranded wire. The "Z" in the part number often indicates a specific cable length or a specialized configuration (like a Folded or Shielded variant) depending on the full 3M catalog suffix. --- ### Applications * **Industrial Controls:** Connecting PLCs to interface modules. * **Computing:** Internal data transfer between motherboards and peripheral daughtercards. * **Medical Equipment:** High-density signal routing in compact enclosures. * **Testing Equipment:** Used in jigs where frequent disconnection is required. --- ### Ordering Code Breakdown (Example) While specific to 3M's internal system, the code generally follows this logic: * **M3:** 3M Series identifier. * **SMS:** Socket to Card Edge configuration. * **Z:** Specific length or plating indicator (e.g., Lead-free/RoHS compliance). * **R:** Packaging or Revision code (often "Reverse" orientation or "RoHS").
