The part number **2294700-R** generally refers to a specific series of high-performance **Micro-D connectors** or specialized cabling components, often manufactured by companies like **TE Connectivity** or specialized hardware vendors. In the context of electronic components, this part is typically associated with high-density interconnect systems. --- ## Technical Overview The 2294700-R is a high-reliability component designed for environments where space is limited and signal integrity is critical. Below is a breakdown of its primary electronic and mechanical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Micro-D (Subminiature D) Connector / Cable Assembly | | **Number of Positions** | Typically 9 to 37 positions (depending on specific dash number) | | **Pitch** | 0.050" (1.27 mm) centers | | **Current Rating** | ~3 Amps per contact | | **Operating Temp** | -55°C to +125°C | | **Termination** | Solder cup, pre-wired, or PCB mount | --- ## Key Components & Construction ### 1. Housing and Shielding The "-R" suffix often denotes **RoHS Compliance** (Restriction of Hazardous Substances). The shell is usually made of aluminum alloy with electroless nickel plating, providing excellent EMI/RFI shielding to protect sensitive electronic signals from interference. ### 2. Contacts (Pins/Sockets) * **Material:** Beryllium copper or gold-plated copper alloy. * **Design:** Uses a "Twist Pin" system which provides multiple points of contact, ensuring a stable electrical connection even under extreme vibration or shock. ### 3. Dielectric Insulator Typically made of **Polyphenylene Sulfide (PPS)** or similar high-grade liquid crystal polymers. This provides high dielectric strength and resistance to chemicals. --- ## Applications Electronic parts in this category are rarely used in consumer electronics. Instead, they are found in: * **Aerospace & Defense:** Avionics, missile guidance systems, and satellite communications. * **Medical Equipment:** Portable imaging devices and diagnostic tools. * **Industrial Automation:** High-density robotics and sensors. --- ## Part Number Breakdown (General) | Segment | Meaning | | :--- | :--- | | **2294700** | Base series number identifying the physical footprint and contact arrangement. | | **-R** | Indicates RoHS compliance (Lead-free materials). |
