## Technical Overview: A-DF25LL-WP-R The **A-DF25LL-WP-R** is a specialized electronic connector produced by **Assmann WSW Components**. It belongs to the D-Subminiature family, specifically designed for environments where moisture and dust protection are critical. --- ### 1. Component Specifications The following table outlines the primary technical characteristics of the A-DF25LL-WP-R: | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Subminiature | | **Gender** | Female (Socket) | | **Number of Positions** | 25 Pins | | **Mounting Type** | Through Hole, Right Angle (R/A) | | **Waterproof Rating** | IP67 / IP68 | | **Termination** | Solder | | **Contact Material** | Copper Alloy | | **Plating** | Gold (Flash or specified thickness) | | **Shell Material** | Steel, Tin Plated | --- ### 2. Key Electronic & Physical Attributes #### Waterproofing (WP Designation) The "WP" in the part number signifies **Waterproof**. This connector includes an integrated O-ring or silicone seal and a potting compound. This ensures that the connection remains secure even when exposed to splashing water or brief immersion, making it ideal for outdoor industrial equipment. #### Right Angle Orientation (LL-R) The "LL" typically refers to the lead length or mounting style, while the "R" indicates a **Right Angle** PCB mount. This allows the connector to be mounted on the edge of a circuit board, with the interface facing outward horizontally, saving vertical space within an enclosure. #### 25-Pin Configuration (Density) This is a standard density D-Sub 25 (DB25). While historically used for parallel printer ports, in modern electronics, it is frequently used for: * RS-232 serial communication. * Multi-channel analog audio. * Industrial control signals (PLC interfaces). --- ### 3. Electrical Performance Limits To ensure circuit safety, the following electrical limits should be observed: ```yaml Electrical_Limits: Current_Rating: 3A to 5A per contact Voltage_Rating: 250V AC/DC Insulation_Resistance: 5000 MΩ Min Dielectric_Strength: 1000V AC for 1 minute Operating_Temperature: -55°C to +105°C ``` --- ### 4. Common Applications * **Industrial Automation:** Sensors and actuators in damp environments. * **Telecommunications:** Outdoor base station interfaces. * **Marine Electronics:** Navigation and sonar equipment. * **Medical Equipment:** Devices requiring frequent sanitization or fluid resistance.
