The **HAP-02-R/Q** refers to a specific series of **Wire-to-Board Connectors**, commonly associated with the **JST (Japan Solderless Terminal)** product line, specifically the **PA Series**. These are used extensively in electronics for secure, low-profile power and signal connections. --- ### 1. Technical Specifications Below are the primary electronic and mechanical characteristics of the HAP-02-R/Q: | Feature | Specification | | :--- | :--- | | **Series** | PA Series (Wire-to-Board) | | **No. of Circuits** | 2 Positions | | **Pitch** | 2.0 mm | | **Current Rating** | 3.0A AC/DC (using AWG #22) | | **Voltage Rating** | 250V AC/DC | | **Contact Resistance** | 10 mΩ Max (Initial) | | **Insulation Resistance** | 1,000 MΩ Min | | **Operating Temp** | -25°C to +85°C | --- ### 2. Component Breakdown The "HAP-02-R/Q" designation describes the housing unit: * **HA (Housing):** Indicates the part is the plastic housing body that holds the crimp terminals. * **P (Plug):** This specifically denotes a **Panel Mount Plug**. Unlike standard socket housings, this part is designed to be mounted through a cutout in a chassis or panel. * **02:** Represents the number of circuits (2 pins). * **R / Q:** These suffixes usually refer to color or material variations (e.g., "R" for Red or specific UL flame retardancy ratings). --- ### 3. Key Electronic Features * **Secure Locking Mechanism:** Features a "device-locking" structure (often referred to as a positive lock) that prevents accidental disconnection due to vibration or tension. * **Panel Lock Construction:** The "P" version includes side "ears" or clips that snap into a panel, providing a fixed interface point for external connections. * **Polarization:** The housing is keyed to ensure that the connector cannot be inserted upside down, protecting the circuit from reverse polarity. --- ### 4. Typical Applications These connectors are found in compact electronic assemblies where space is limited but high reliability is required: 1. **Consumer Electronics:** Power supply inputs for small appliances. 2. **Industrial Controls:** Signal transmission between internal PCBs and external control panels. 3. **LED Lighting:** Used for connecting LED strips to drivers.
