FAQ
Find answers to common questions about circular connectors,
What types of rectangular connectors does SINOCONNECTORS provide?
SINOCONNECTORS provides PCB and board-to-board connectors, modular and hybrid connectors, high-current mixed connectors, high-speed transmission connectors, environmental-resistant connectors, pogo pin connectors, zero insertion force connectors, and application-specific rectangular connector solutions.
What is the difference between PCB connectors and board-to-board connectors?
PCB connectors are designed to connect electrical interfaces directly to a printed circuit board. Board-to-board connectors are specifically designed to create electrical connections between two separate PCBs, with different pitch, orientation, and spacing options available.
What pitch options are available for rectangular connectors?
Available pitch options vary by series and application. Our product range includes compact high-density configurations such as 1.27 mm, 1.905 mm, 2.0 mm, and 2.54 mm pitch solutions, as well as application-specific configurations.
What are high-density rectangular connectors?
High-density rectangular connectors integrate a large number of electrical contacts into a compact connector footprint. They are suitable for space-constrained electronic equipment, PCB systems, industrial control equipment, and other applications requiring high contact density.
What is the difference between modular and hybrid connectors?
Modular connectors use configurable modules to create different interface combinations. Hybrid connectors can combine different contact types within one connector, allowing power, signal, and data connections to be integrated into a single interface.
Are rectangular connectors suitable for high-speed data transmission?
Yes. Selected rectangular connector series are designed for high-speed signal and data transmission. The appropriate series depends on transmission rate, shielding requirements, contact layout, cable design, and the electrical characteristics of your application.
What are the advantages of POGO pin rectangular connectors?
POGO pin connectors use spring-loaded contacts to provide reliable electrical contact with convenient mating. They are suitable for docking systems, test equipment, charging interfaces, and applications requiring repeated connection cycles.
Can rectangular connectors be customized for our application?
Yes. Customization can include contact layout, pitch and interface configuration, mixed power and signal contacts, shell and housing design, PCB mounting configuration, cable integration, environmental adaptation, and special mechanical structures.
What industries use rectangular and modular connectors?
Rectangular and modular connectors are widely used in industrial automation, transportation, energy and power equipment, telecommunications, aerospace and defense systems, electronic equipment, instrumentation, and other industrial applications.
Do you provide cable assemblies for rectangular connectors?
Yes. Cable integration and application-specific cable assembly solutions can be provided according to connector type, wiring requirements, termination method, installation environment, and project specifications.
What quality standards do your rectangular connectors meet?
Quality and compliance requirements depend on the connector series and application. Products are supported by controlled manufacturing, inspection, and electrical, mechanical, and environmental testing. Please contact us with the required standard or certification so we can confirm the appropriate product.
Do you support OEM and ODM rectangular connector projects?
Yes. We support OEM and ODM projects including application review, connector selection, configuration development, mechanical design, prototype support, manufacturing, inspection, and production support.
What is the typical lead time for rectangular connectors?
Lead time depends on the connector series, configuration, customization requirements, order quantity, and production schedule. Standard and customized products may have different lead times. Send us your requirements for a project-specific delivery estimate.
What is the minimum order quantity for rectangular connectors?
Minimum order quantity depends on the connector series, configuration, and whether the product is standard or customized. Please provide the required series, specifications, and estimated quantity so our team can confirm the appropriate MOQ.
Do you provide samples for evaluation and testing?
Sample availability depends on the connector series and configuration. For engineering evaluation, please provide your required model, contact arrangement, application requirements, and expected quantity so we can confirm a suitable sample solution.
How do I choose the right rectangular connector for my application?
The correct connector depends on your electrical, mechanical, installation, and environmental requirements. For faster selection, please provide:
- Application and operating environment
- Number and type of contacts
- Power, signal, or data requirements
- PCB, board-to-board, or cable connection method
- Connector size and installation space
- Required pitch or interface
- Environmental or reliability requirements
- Estimated order quantity
