The **15PA-16-R** is a specific electronic hardware accessory primarily associated with the **Honeywell Sensing and Productivity Solutions** (MicroSwitch) product line. It is not an active electronic component (like a transistor) but rather a critical mechanical interface component used in switch assemblies. --- ### 1. Component Overview The 15PA-16-R is a **Replacement Lever/Actuator** for large basic switches. It acts as the physical interface between the mechanical system and the internal switch mechanism. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Honeywell (Sensing and Productivity Solutions) | | **Product Category** | Switch Accessories / Actuators | | **Type** | Straight Lever | | **Compatibility** | BZ, BA, BM, and BE Series Large Basic Switches | | **Material** | Steel (with corrosion-resistant plating) | | **RoHS Status** | Compliant | --- ### 2. Physical Design and Function This part is designed to modify the operating characteristics of a basic microswitch. * **Lever Style:** It is a straight leaf-style lever. * **Mechanical Advantage:** By extending the length of the switch trigger, it reduces the amount of force required to actuate the switch (Operating Force) while increasing the travel distance. * **Adjustment:** These levers are often "field adjustable," meaning they can be formed or bent slightly to meet specific physical clearance requirements in a machine. --- ### 3. Technical Installation When integrating the 15PA-16-R into an electronic assembly, it is typically mounted using a specific bracket or by snapping into the housing of a compatible switch body. ```text Assembly Logic: [External Force] -> [15PA-16-R Lever] -> [Switch Plunger] -> [Internal Contacts] ``` #### Key Switch Series Supported: 1. **BZ Series:** Standard premium large snap-action switches. 2. **BA Series:** High-capacity switches. 3. **BM Series:** Precision switches for high-accuracy applications. --- ### 4. Applications The 15PA-16-R is commonly found in industrial and commercial environments where heavy-duty switching is required: * **Limit Switching:** Detecting the end-of-travel for a motorized arm. * **Safety Interlocks:** Ensuring a door or panel is closed before a machine starts. * **Conveyor Systems:** Sensing the presence of items passing on a belt. ---
