Unlock the PA Terminal Connector
 A Reliable Choice for 2.0mm Pitch High-Density Connections

        Amid the wave of new energy and industrial automation, the reliability and efficiency of electrical connections have become core indicators of equipment performance. Leveraging its accumulated technical expertise from deep engagement in the connector field, Guangdong Deke Electric Co., Ltd. has launched the PA2.0 terminal connector. Adhering to industry-leading design standards and stringent quality control, this product provides highly reliable connection solutions for new energy vehicles, industrial control, consumer electronics, and other fields. Below is an in-depth analysis of this star product from three dimensions: technical breakthroughs, application scenarios, and industry value.​

2.0mm pitch

precision-engineered to define new connection standards

        The PA2.0 features the industry-universal 2.0mm standard pitch and a single-row 2-16Pin harness configuration, ensuring perfect compatibility with mainstream device interfaces. Its terminals are made of high-conductivity phosphor bronze, with tin plating and other surface treatments, boasting excellent conductive performance to guarantee stable transmission of signals and currents. Its rated current varies depending on the wire diameter, and common specifications can carry 3A - 10A, meeting the power requirements of various electronic devices. Meanwhile, the insulation design inside the harness enables an insulation resistance of over 1000MΩ, effectively preventing leakage and short circuits and ensuring the safety of equipment and personnel.​

        The PA2.0 adopts a dual-locking structure mechanism: the housing is equipped with a mechanical latch, which achieves a stable connection through thumb-press operation. It can resist accidental disconnection caused by vibration or external force, providing stronger and safer retention force. In addition, the insertion guide slots ensure precise docking of the connectors, avoiding reverse or misaligned insertion—thereby enhancing the connection reliability of equipment in industrial, automotive electronics and other fields, and being particularly suitable for multi-circuit scenarios.​

PA2.0 Pin Header: The Core Support for Stable Connections

        As a crucial interface connecting circuit boards and external devices, PA pin headers boast excellent mechanical strength and electrical performance. The main body of the pin header is made of nylon (PA66) UL94V-2(0) material, which features high strength, high temperature resistance, flame retardancy and other properties, enabling it to maintain stability under harsh working conditions. Taking the common single-row PA pin header as an example, it has a pitch of 2.0mm and offers different specifications with 2-16 pins, meeting the connection requirements of circuits with varying complexities.

        In terms of electrical parameters, the PA2.0 pin header has a rated voltage of up to 100V AC/DC, and its rated current varies depending on the pin specifications and material, generally ranging from 3A to 5A. It features low contact resistance: the initial contact resistance is below 10mΩ, and it can remain below 20mΩ even after environmental tests, ensuring low-loss and stable signal transmission. The insulation 
resistance is also as high as 1000MΩ or more, with a voltage resistance capability of AC800V for 1 minute, effectively guaranteeing the safety and reliability of electrical connections. In addition, the pins of the pin header are made of phosphor bronze and undergo tin plating treatment, which enhances their anti-oxidation and corrosion resistance, thereby extending their service life.

PA2.0 SMD: Precise and Efficient Surface Mounting

        The PA 2.0 SMD is suitable for Surface Mount Technology (SMT), providing an ideal solution for the miniaturization and high-density assembly of circuit boards. It comes in various packaging forms, including top-mount and side-mount types, which can be flexibly selected according to the design requirements of the circuit board. Taking the top-mount BMxB-PASS-TF series as an example, it features a pin pitch of 2.0mm and offers different specifications with 2-15 positions, making it suitable for various circuit layouts.

         The PA 2.0 SMD also excels in electrical performance, with a rated voltage of 100V AC/DC and a rated current of up to 3A. Its contact resistance and insulation resistance are comparable to those of the PA pin header, ensuring stable signal transmission and reliable electrical isolation. In terms of production processes, the PA SMD adopts advanced manufacturing technologies, featuring high pin precision that enables accurate soldering with circuit boards, thus improvingproduction efficiency and product quality. Meanwhile, it has excellent high-temperature resistance, capable of withstanding the high temperatures during reflow soldering, which meets the needs of large-scale automated production.

PA2.0

A "versatile all-rounder" for connections across multiple fields

Consumer Electronics: Safeguarding "Small yet Refined" Products

        In the internal circuit connections of portable devices such as smartphones, tablets, and laptops, the compact size of the PA2.0 terminal connector perfectly meets the miniaturization needs of these devices. For instance, both the power supply connection between a tablet's battery and its motherboard, and the signal transmission between a laptop's touchpad and its motherboard, can achieve low-loss signal transfer via the PA2.0 harness. Moreover, its temperature resistance range of -40°C to 100°C can cope with temperature fluctuations during device operation. In addition, the connection between sensors and the main control board in smart wearable devices (such as smart watches and bracelets) also relies on its precision SMD design with a 2.0mm pitch, ensuring the real-time performance of data collection.

Industrial Control: Steadfast as a Mountain in the "Harsh Battlefield"

        Between the control panels and executive components of industrial automation equipment, the PA2.0 pin header, leveraging the high-strength properties of glass fiber-reinforced PBT material, can withstand complex shop-floor environments such as vibrations and dust. In the I/O interface connections of PLCs (Programmable Logic Controllers) and the signal feedback circuits of servo motors, its rated current of 3A-5A and voltage resistance of 100V enable stable transmission of control signals and driving currents. The design with insulation resistance exceeding 1000MΩ effectively avoids electromagnetic interference in industrial environments.

Automotive Electronics: Durable and Rugged in the "Mobile Space"

         In the connections of in-vehicle multimedia systems and air-conditioning control panels within the car cabin, the wear-resistant nylon outer sheath of the PA2.0 harness can resist abrasion caused by oil stains and friction inside the vehicle, ensuring the continuous and stable transmission of audio and temperature adjustment signals. Meanwhile, auxiliary electronic components near the car engine compartment (such as sensor wiring) can also use PA2.0 connectors. Its high-temperature resistance enables it to adapt to the temperature changes from -40°C to 100°C in the compartment, ensuring the accuracy of data collection.

Smart Home: Making "Life Assistants" Smarter

        Smart home appliances (such as floor-cleaning robots, smart refrigerators, and air conditioners) extensively adopt the combined solution of PA2.0 SMDs and pin headers for internal module connections. For example, the laser radar module and main control board of a floor-cleaning robot achieve high-density wiring through PA2.0 SMDs, saving internal space; the connection between the temperature control panel and refrigeration system of a smart refrigerator relies on the flexible wiring capability of PA2.0 harnesses, adapting to the complex structural layout inside the refrigerator.

Medical Devices: Accurate Signal Transmission on the "Health Defense Line"

        In portable medical instruments (such as blood glucose meters and ECG monitors), the PA2.0 connector features low contact resistance (initial resistance ≤10mΩ), which can ensure the accurate transmission of weak bioelectrical signals, aiding the devices in achieving high-precision detection. Its insulation design complies with the safety standards for medical devices, effectively preventing the risk of electric leakage and ensuring safety for both medical staff and patients during use.
