The **MHDPPK37-R-K** is a high-quality connector kit manufactured by **MH Connectors**. It is primarily designed for D-Subminiature (D-Sub) connections, commonly used in serial data communication and industrial equipment. --- ## 1. Product Overview This part number represents a complete kit that includes a **37-pin D-Sub plug** and a **plastic backshell (hood)**. ### Key Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Sub Plug (Male) | | **Number of Positions** | 37 Pins | | **Shell Size** | DC (Standard 37-pin size) | | **Shell Material** | Polyamide (Plastic), UL94V-0 Rated | | **Contact Plating** | Gold Flash over Nickel | | **Mounting Type** | Cable Mount (Solder Cup) | | **Orientation** | Straight Exit | --- ## 2. Component Breakdown ### A. The Connector (Plug) The internal electronic component is a **37-way male D-sub**. * **Solder Cups:** The pins have hollowed "cups" at the back, allowing wires to be inserted and soldered manually. * **Contacts:** Usually rated for approximately **5 Amps** per contact. ### B. The Backshell (Hood) The "PPK" in the part number refers to the **MHDPPK series** hood. * **Material:** It is made of black Polyamide (Plastic). Unlike metalized versions, this provides insulation but not EMI/RFI shielding. * **Cable Strain Relief:** Includes a high-grade plastic strain relief insert to prevent the wires from being pulled out of the solder joints. * **Jackscrews:** Comes with 4-40 UNC thumb screws for securing the connector to its mating socket. --- ## 3. Applications The MHDPPK37-R-K is widely used in environments where weight and cost-efficiency are prioritized over heavy shielding: * **Industrial Controls:** Connecting PLC units to peripheral devices. * **Networking:** Legacy RS-232/RS-449 serial communication. * **Test Equipment:** Custom cable assemblies for laboratory data acquisition. --- ## 4. Assembly Note To assemble this part, you will typically need: 1. **Soldering Iron:** To attach the wires to the 37 pins. 2. **Wire Strippers:** For 20-28 AWG wire preparation. 3. **Small Screwdriver:** To close the plastic housing and tighten the jackscrews.
