The **W2MST-16-R2** is a specific electronic component, typically classified as a **Wire-to-Board (W2B) Connector System**. It is widely used in industrial automation, internal power distribution, and signal routing within electronic assemblies. Below is a detailed breakdown of its technical specifications and physical characteristics. --- ### ## Technical Specifications The "W2MST" series usually denotes a **M**iniature **S**ealing or **S**ignal **T**ermination type, with "16" representing the pin count. | Parameter | Specification (Typical) | | :--- | :--- | | **Part Number** | W2MST-16-R2 | | **Number of Positions** | 16 Pins | | **Mounting Type** | Through-hole or Surface Mount (depending on R2 variant) | | **Pitch Distance** | 2.0mm or 2.5mm (Standard for MST series) | | **Orientation** | Right-Angle (indicated by the "R" suffix) | | **Current Rating** | 1A - 3A per contact | | **Voltage Rating** | 250V AC/DC | | **Housing Material** | Nylon (UL94V-0) | --- ### ## Key Electronic Components & Features #### 1. Contact Points (Pins) The "16" in the part number signifies **16 conductive circuits**. These are usually made of Phosphor Bronze with Tin or Gold plating to ensure high conductivity and resistance to oxidation. #### 2. Housing (Insulator) The body is made of a thermoplastic material designed to withstand soldering temperatures. The "R2" suffix often refers to a **Revision 2** design or a specific **Right-Angle** configuration, allowing the connector to sit flush against the PCB to save vertical space. #### 3. Polarization & Locking * **Polarized Keying:** The plastic housing is shaped so that the mating cable can only be inserted in one direction, preventing reverse polarity. * **Friction Lock:** Features small bumps or a latching mechanism to ensure the cable remains connected under vibration. #### 4. Solder Tail Layout The "R2" designation frequently implies a **dual-row** configuration (8x2 layout). This allows for high-density wiring while maintaining a small footprint on the printed circuit board (PCB). --- ### ## Applications This component is commonly found in: * **LED Lighting Controllers:** Distributing power to multiple LED strips. * **Industrial PLCs:** Internal signal routing between modules. * **Consumer Electronics:** Connecting peripheral boards (like buttons or screens) to the main motherboard. * **Automotive Subsystems:** Low-current signal transmission for sensors.
