ESQT-107-02-H-D-620

The ESQT-107-02-H-D-620 is a type of rectangular connector commonly used to connect electrical signals between two circuits or a circuit and a device. The connector is made up of two components; the mating header and the mating receptacle. It is a Board to Cable System, meaning that the header is typically mounted on a printed circuit board (PCB) and the receptacle is typically attached to a cable. The electrical connections are made when the header and receptacle are mated together. The connector is designed with durability and surface mountability in mind since it is commonly integrated into challenging and delicate applications. The corrosion resistance and vibration resistance of the connector helps make it suitable for harsh environments. The ESQT-107-02-H-D-620 is a miniaturized connector that provides versatility and compatibility for a variety of space-constrained applications such as tight-fitting compartments in electronic devices or in tight spaces where larger footprint connectors are not applicable. The ESQT-107-02-H-D-620 features a 2.0mm centerline spacing. This is a key factor since a larger centerline will reduce the number of contacts and require a larger shell. Also, the 2.0mm centerline helps space signals to match the centerline of the printed circuit board (PCB). The shell is a two-part, two-piece, metal shell that covering all parts and allowing for modular design and variation. The connector is typically found in applications such as Household Appliances, Business Machine, Audio and Video Equipment, Telecommunications Equipment, Printers, Computer Peripherals, Instrumentation, Industrial Automation, Control and Security, Medical Devices, Test and Measurement, Lighting. It is suited for a wide range of signal types and power applications and its capability to provide a secure connection helps increase the reliability of the device by helping to minimize wear and tear over the life of the product. The ESQT-107-02-H-D-620 is rated up to 600VAC/300VDC and is UL, CSA and ENEC approved. There are 25 contacts on the header and 25 contacts on the receptacle with a maximum current rating of 5 amps. It is designed with a shrouded header to prevent accidental contact with the contacts and a secure locking mechanism to help hold the connector together when mated. Additionally, it features polarization tabs to ensure proper alignment when mating and strain relief regulations to help protect from solder pull-up forces. The connector is designed with a standard RoHS compliant Sn/Pb (tin plated or gold plated) coating, suitable for most electrical applications, both high-frequency and low-frequency. It is recommended when making board-to-board or board-to-cable connections that the contacts be plated with tin or gold for increased performance and reliability.The working principle of the connector is relatively simple. The pins on the receptacle mate with the contacts on the header and create an electrical connection between them. The mating header and the mating receptacle must be correctly aligned before being fully inserted, and once fully inserted the contacts on the receptacle will engage with the pins on the header, creating a good electrical connection. The lock tabs on the header or receptacle will snap into place when the connector is securely connected, to ensure the connection remains secure.All in all, the ESQT-107-02-H-D-620 is a highly reliable type of rectangular connector that can fulfill the requirements of a variety of applications. Its 2.0mm centerline spacing, 600V rating, and robust design makes it the perfect choice for tight spaced applications. Additionally, its secure locking mechanism and strain relief regulations help ensure that the connection remains secure and reliable.
