The **W2CA-13B-R2/N** is a specific electrical accessory, primarily categorized as a **Limit Switch Actuator** or **Head Assembly**, typically associated with industrial sensors or limit switches (most notably from manufacturers like Omron). --- ### 1. General Specifications This part functions as the mechanical interface between a physical object and the internal electrical contacts of a switch. | Feature | Description | | :--- | :--- | | **Component Type** | Actuator Head / Operating Head | | **Actuator Style** | Adjustable Roller Lever | | **Series Compatibility** | Often used with WLC-series or similar limit switch bodies | | **Material** | Heavy-duty metal/alloy (for industrial durability) | | **Environmental Rating** | Usually IP67 (Dust-tight, Water-resistant) | --- ### 2. Detailed Electronic & Mechanical Parts #### A. The Roller (The "R2" Designation) * **Function:** This is the point of contact with the moving machine part. * **Material:** Often made of stainless steel or high-strength resin to minimize friction and wear. * **Operation:** It rotates as it comes into contact with a cam or dog, converting linear motion into rotational motion for the switch. #### B. Adjustable Lever Arm * **Mechanism:** The "13B" typically refers to the arm length and adjustability. * **Feature:** This allows the user to change the length of the arm or the angle of the roller to fine-tune the "trip point" of the electronic circuit inside the switch body. #### C. Return Spring (Internal) * **Role:** An internal torsion spring ensures that once the external force is removed, the lever returns to its "Normal" (Resting) position. * **Electronic Impact:** This determines the reset speed of the NO (Normally Open) and NC (Normally Closed) contacts. #### D. Cam and Shaft * **Internal Linkage:** The lever is attached to a shaft that rotates a cam inside the head. * **Switch Trigger:** This cam pushes down on the plunger of the switch body, physically moving the electrical contacts to open or close the circuit. --- ### 3. Application Use Case In an industrial control system, the **W2CA-13B-R2/N** would be part of a circuit designed to: 1. **Detect End-of-Travel:** Stopping a motor when a carriage reaches a certain point. 2. **Object Counting:** Triggering a pulse to a PLC (Programmable Logic Controller) every time a part passes on a conveyor. 3. **Safety Interlocking:** Ensuring a machine door is closed before allowing the circuit to energize. --- ### 4. Mounting and Integration The "/N" suffix usually denotes a specific mounting or revision standard (often "New" or a specific thread type for the mounting screws). ```markdown Note: This part is an actuator head ONLY. It does not contain the electrical contact block itself. It must be paired with a switch body (e.g., WLCAL4-N) to function as a complete electronic component. ```
