The term **34N-R** typically refers to a specific series of **Wire-to-Board Connectors** or **Crimp Terminal Housings**, most commonly associated with manufacturers like JST (Japan Solderless Terminals) or compatible electronic component distributors. --- ### 1. Component Overview The "34N-R" designation usually identifies a **housing component** for a connector with 34 positions (pins). These are widely used in industrial electronics, automotive systems, and computer peripherals to connect wire harnesses to printed circuit boards (PCBs). ### 2. Technical Specifications While exact specs can vary by manufacturer, a standard 34N-R series connector generally adheres to the following parameters: | Feature | Typical Specification | | :--- | :--- | | **Number of Positions** | 34 Pins | | **Pitch (Spacing)** | Often 2.0mm or 2.54mm (depends on specific series) | | **Contact Type** | Female Socket (Housing for Crimp Terminals) | | **Material** | Nylon 66 (UL94V-0 Rated) | | **Voltage Rating** | 250V AC/DC | | **Current Rating** | 1A - 3A (depending on wire gauge) | | **Orientation** | Right-angle or Straight (R often denotes Right-angle or Red) | --- ### 3. Key Features * **Polarization:** The housing is usually "keyed" to prevent accidental reverse insertion into the header. * **Locking Mechanism:** Many 34N-R housings feature a friction lock or a mechanical latch to ensure the connection stays secure under vibration. * **Crimp Termination:** Requires compatible metal crimp terminals (sold separately) to be attached to wires before being inserted into the plastic housing. ### 4. Common Applications 1. **LCD/LED Displays:** Connecting control boards to the panel. 2. **Internal Computer Wiring:** Used for data headers or power distribution. 3. **Industrial Controllers:** Connecting sensors and actuators to a PLC or custom PCB. 4. **Automotive Electronics:** Signal routing for dashboard or infotainment systems. --- ### 5. Identification Code Breakdown If you are looking at a part number like **PHR-34** or **34N-R**, the code usually breaks down as follows: * **34:** The number of circuits/poles. * **N:** Often indicates a specific material or "Natural" color (though sometimes used for "Nylon"). * **R:** Can indicate "Right Angle" orientation for the mating header, or "Red" color coding in some manufacturer catalogs.
