The **M2SBS-414-R/N** is a specialized precision mechanical component, typically categorized as a **Metric Self-Broaching Standoff**. These parts are essential in electronic packaging and PCB (Printed Circuit Board) manufacturing to provide secure mounting points, spacing, and grounding between components. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by manufacturers like PennEngineering (PEM) or similar high-end hardware providers. | Feature | Specification | Description | | :--- | :--- | :--- | | **Type** | M2SBS | Metric Self-Broaching Standoff | | **Thread Size** | M4 | 4.0 mm diameter metric thread | | **Length (L)** | 14 | 14 mm standoff height | | **Material** | R | Typically indicates Hardened Carbon Steel | | **Finish** | N | Typically indicates Nickel Plated finish | --- ### 2. Electronic Applications While the part is mechanical, its role in an electronic system is critical for several reasons: * **PCB Spacing:** It maintains a precise 14mm gap between two PCBs or between a PCB and a metal chassis to prevent short circuits. * **Grounding (EMI/RFI):** Because it is made of nickel-plated steel, it provides a low-resistance electrical path. This is used to ground the PCB to the enclosure to reduce electromagnetic interference. * **Structural Integrity:** The "Self-Broaching" nature means the part is pressed into a non-ductile material (like a resin board or certain plastics/metals). The knurled shank "cuts" into the material to provide high torque-out and pull-out resistance. --- ### 3. Installation Mechanism The M2SBS series is designed for "Press-In" installation. 1. **Hole Preparation:** A specific diameter hole is drilled or punched into the substrate. 2. **Broaching:** As the standoff is pressed in, the serrated teeth (knurls) cut into the surface of the hole. 3. **Cold Flow:** In some materials, the displaced material flows into the undercut of the standoff, locking it permanently in place. --- ### 4. Comparison with Standard PEM Standoffs | Feature | Self-Broaching (M2SBS) | Standard Self-Clinching (SO) | | :--- | :--- | :--- | | **Substrate Compatibility** | Harder materials / Brittle boards | Ductile metals (Aluminum, Steel) | | **Installation Method** | Broaching/Cutting | Displacement/Clinching | | **Conductivity** | High (Nickel Plating) | Varies by finish |
