The **F2VS-K4-R** is a specific electronic component, typically categorized as a **Terminal Block Connector** or a **Spring-Clamp Terminal** unit, often associated with industrial automation brands like **Keyence** (specifically for their Vision System or Sensor controller accessories). Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Technical Specifications This part is designed to facilitate secure, screwless connections between field wiring and electronic control units. | Feature | Specification | | :--- | :--- | | **Type** | Spring-clamp / Push-in Terminal Block | | **Number of Pins** | 4-Pin | | **Connection Method** | Cage Clamp / Spring Pressure | | **Pitch** | Typically 3.5mm or 5.0mm (standard industrial) | | **Mounting Type** | PCB Mount or Plugin Header | | **Contact Material** | Copper Alloy with Tin/Gold Plating | --- ## 2. Key Electronic Components & Features ### A. Spring-Clamp Mechanism Unlike traditional screw terminals, the "K4-R" variant uses a stainless steel spring. - **Benefit:** Provides constant pressure on the wire, making it resistant to vibrations and thermal expansion, which prevents loose connections over time. - **Actuation:** Usually requires a small flat-head screwdriver to press the orange/red lever to insert the wire. ### B. Contact Resistance The internal busbars are designed for low contact resistance (typically **< 20mΩ**). This ensures minimal voltage drop across the connector, which is critical for sensitive sensor signals (like those used in Keyence F2VS systems). ### C. Housing (Insulation) The body is made of **Polyamide (PA66)** or a similar high-grade thermoplastic. - **Flammability Rating:** Usually UL94 V-0. - **Dielectric Strength:** Capable of withstanding 1.5kV to 2.5kV AC for one minute without breakdown. --- ## 3. Pinout and Wiring Typical Configuration While specific to the device it plugs into, a 4-pin configuration in this series generally follows this standard: | Pin | Function (Typical) | Wire Gauge Compatibility | | :--- | :--- | :--- | | 1 | +24V DC Power | 24 - 16 AWG | | 2 | 0V / GND | 24 - 16 AWG | | 3 | Signal Input / Trigger | 24 - 16 AWG | | 4 | Output / Strobe | 24 - 16 AWG | --- ## 4. Application Usage The **F2VS-K4-R** is predominantly used in: * **Vision Systems:** Connecting power and triggers to smart cameras. * **Sensor Controllers:** Interfacing digital I/O between a PLC and a sensor head. * **Vibration Environments:** Since there are no screws to back out, it is preferred in automotive assembly lines and high-speed packaging machinery. ---
