FAQ

Common Sourcing Questions

Common Sourcing Questions in Relay & Contactor

What is the minimum order quantity (MOQ) for industrial relays?

The typical MOQ for industrial relays starts from 500 units for standard models, but it can vary based on customization. We offer flexible options, such as reducing MOQ to 100 units for premium clients or high-volume orders. This helps buyers manage inventory costs while ensuring production efficiency. Factors like relay type (e.g., electromechanical or solid-state) and certification requirements (e.g., CE or UL) may influence MOQ. We recommend discussing your specific needs to tailor an optimal order size during the quotation process.

Can contactors be customized for specific voltage and current ratings?

Yes, we provide full customization for contactors to match your exact voltage (e.g., 24V to 600V) and current ratings (e.g., 10A to 400A). Our process includes a detailed consultation to review your application, followed by engineering design and prototyping. Custom options cover coil voltages, auxiliary contacts, and enclosure types, with international certifications like IEC 60947 ensuring compliance. Lead times for custom contactors range from 4-6 weeks, including sample approval to guarantee performance before bulk production.

Are your relays and contactors compliant with international certifications such as CE or ISO?

All our relays and contactors meet key international certifications, including CE for EU market access, ISO 9001 for quality management, and RoHS for environmental safety. We conduct regular audits to maintain standards, ensuring products are suitable for industrial applications like automation and power systems. Buyers can request certification documents upfront to verify compliance. This reduces import risks and supports smooth customs clearance in global shipments.

How do I request samples for testing relays before a full order?

You can request samples by providing specifications (e.g., relay type and load requirements) through our online portal. We offer free samples for standard models with a nominal fee for custom versions, shipped within 5-7 days via express couriers like DHL. Testing includes performance checks for durability and electrical ratings. Once approved, the sample serves as a reference for bulk orders, helping avoid defects. MOQ adjustments are available post-approval to streamline procurement.

What packaging options are available for relays to ensure safe international shipping?

We use robust packaging for relays, including anti-static bags, foam inserts, and corrugated cartons to prevent damage during transit. Options comply with ISTA standards for shock resistance, with labeling for fragile items. For bulk orders, palletized crates or seaworthy containers are available. This minimizes transit risks and costs, especially for air or sea freight. We also handle export documentation, such as packing lists, to facilitate customs clearance and on-time delivery.

What are the standard lead times for contactor deliveries to international destinations?

Lead times for contactor deliveries typically range from 3-5 weeks for standard stock items and up to 8 weeks for custom orders. This includes production, quality control, and shipping via sea or air freight. We prioritize express options for urgent needs, with real-time tracking through partners like FedEx. Factors like destination port, customs clearance, and order size affect timelines. We recommend confirming ETAs during quoting to align with your project schedules.

How do you handle quality control for relays during manufacturing?

Our quality control involves rigorous testing at multiple stages: incoming materials inspection, in-process checks for parameters like contact resistance, and final audits against ISO 9001 standards. We use automated systems for reliability testing, including life cycle and environmental simulations. Certifications like UL ensure safety, and we provide detailed reports for buyer review. This proactive approach minimizes defects and returns, supporting consistent performance in applications such as automotive or HVAC systems.
