The **M2PHSL-11-R2** is a specific model within the **M2PHSL series**, which consists of high-performance, low-profile **Small Form-factor Pluggable (SFP)** connector systems, typically used in high-speed networking and telecommunications hardware. --- ### 1. General Specifications This part is essentially a surface-mount (SMT) connector designed to interface with SFP, SFP+, or related transceiver modules. | Feature | Specification Details | | :--- | :--- | | **Component Type** | SFP/SFP+ 20-Pin Connector | | **Mounting Style** | Surface Mount (SMT) | | **Pitch** | 0.8 mm | | **Orientation** | Right Angle / Horizontal | | **Termination** | Solder | | **Application** | Data networking, Switches, Routers, Servers | --- ### 2. Physical & Material Composition The "R2" suffix often denotes specific revision or packaging standards (such as Tape & Reel for automated assembly). * **Housing:** High-temperature thermoplastic (UL 94V-0 rated), designed to withstand reflow soldering temperatures. * **Contacts:** High-conductivity Copper Alloy. * **Plating:** Typically features Gold (Au) plating on the contact area to ensure low signal resistance and prevent oxidation, with Tin (Sn) on the solder tails. * **Shielding:** Usually paired with a metal "cage" (sold separately or as a kit) to manage Electromagnetic Interference (EMI). --- ### 3. Electrical Characteristics These connectors are engineered to handle high-frequency signals with minimal loss. * **Data Rates:** Supports 1Gbps (SFP) up to 10Gbps+ (SFP+), depending on the system integration. * **Current Rating:** Typically 0.5A per contact. * **Voltage Rating:** 30V AC (RMS)/DC. * **Contact Resistance:** $\leq$ 100 m$\Omega$ (initial). * **Insulation Resistance:** $\geq$ 1000 M$\Omega$. --- ### 4. Pin Configuration (Standard 20-Pin) As an SFP-style connector, the M2PHSL-11-R2 follows the standard pinout for high-speed differential pairs and control signals: | Pin Range | Function Type | Description | | :--- | :--- | :--- | | **1, 10, 11, 20** | Ground (Vee) | Signal Ground | | **12, 13** | Receive (RX) | RD- and RD+ Differential Pairs | | **18, 19** | Transmit (TX) | TD- and TD+ Differential Pairs | | **15, 16** | Power (Vcc) | 3.3V Power Supply | | **Others** | Control/Logic | Mod_ABS, TX_Fault, RX_Loss, I2C (SDA/SCL) | --- ### 5. Common Use Cases * **Network Interface Cards (NICs):** Providing the physical interface for fiber optic or copper Twinax cables. * **Data Center Switches:** Enabling modular port configurations. * **Industrial Automation:** High-speed data uplink for PLC systems.
