## Overview of DTM13-12PB-R005 The **DTM13-12PB-R005** is a specialized, ruggedized electronic connector part of the DEUTSCH DTM series by TE Connectivity. It is primarily designed for high-reliability applications in harsh environments, such as automotive, marine, and industrial machinery. Unlike standard cable-to-cable connectors, the **DTM13** series specifically refers to **PCB headers**, meaning this component is mounted directly onto a printed circuit board. --- ### Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Series** | DEUTSCH DTM | | **Contact Type** | Pin (Male) | | **Number of Positions** | 12 | | **Mounting Type** | PCB Mount - Right Angle | | **Keying** | B Key (Usually coded Gray) | | **Current Rating** | 7.5 Amps per contact | | **Operating Temperature** | -55°C to +125°C | | **IP Rating** | IP68 / IP6K9K (when mated) | --- ### Electronic and Mechanical Components #### 1. Housing and Insulation The body is constructed from high-grade thermoplastic. The "R005" suffix typically indicates a specific modification, often involving **90-degree (right angle) pins** and a mounting flange that allows the connector to be bolted to an enclosure or bulkhead. #### 2. Contacts (Pins) The 12 pins are made of copper alloy and are usually gold or nickel-plated to ensure low resistance and prevent oxidation. Since this is a DTM series, it uses **Size 20 contacts**, which are smaller than the standard DT series, allowing for higher density in a smaller footprint. #### 3. Keying and Color Coding (B-Key) The "B" in the part number signifies the **Keying Configuration**. - **Visual Aid:** The B-key is typically **Gray**. - **Function:** It ensures that only a matching "B-Key" DTM plug can be inserted, preventing cross-connection errors in systems with multiple identical 12-pin connectors. #### 4. Environmental Sealing The header features an integrated interface seal. When mated with a DTM06-12SB plug, it creates a vacuum-tight seal against moisture, dust, and pressurized steam. --- ### Applications * **Engine Control Units (ECUs):** Providing an interface between the board and the wiring harness. * **Transmission Controllers:** High vibration resistance makes it ideal for gearbox mounting. * **Sensor Hubs:** Consolidating multiple low-current sensor signals into a single PCB. ---
