Connector & Cable Assembly FAQ

Q1: Can your connectors/cable assemblies be customized? What is the minimum order quantity (MOQ)?

A: We support full-category customization, and can provide exclusive design and prototyping according to your drawings, parameters (electrical/mechanical/environmental performance) and application scenarios (such as military/automotive/medical). The MOQ for standard products is as low as 500pcs, and the MOQ for customized parts is negotiated based on product complexity. We accept both small-batch trial orders and large-volume orders.

Q2: What is the service life, temperature resistance, waterproof and other environmental performance of the products?

A: The full range of products can provide different protection levels (such as IP67/IP68 waterproof), wide temperature range (-40℃~+85℃ and above), high vibration/impact resistance as required. All products have passed the full electrical, mechanical and environmental performance tests in the laboratory, ensuring long-term stable use in complex working conditions such as industry, military and automotive.

Q3: What are the application fields of your products? Are they suitable for my industry?

A: Our core coverage includes 7 major fields: data communication, industrial control, new energy, medical electronics, equipment manufacturing, military supporting, and automotive wiring harness. High-frequency/low-frequency/fiber-optic/industrial/high-speed connectors and various cable assemblies can meet the stringent requirements of industrial automation, new energy vehicles, medical equipment, military equipment and other segmented scenarios.

Q4: What are the production lead times for standard and customized products?

A: The regular lead time for standard products is 3-7 working days; the prototyping cycle for customized parts is 7-15 working days, and the mass production cycle is 15-30 working days. We can coordinate priority production scheduling according to your urgent order requirements.
