Overview
The FVDWS1.25-M4(LF) is a high-performance electrical connector designed for industrial applications requiring dependable signal transmission. Its 1.25-mm pitch and M4 threaded locking mechanism cater to space-constrained installations while preventing accidental disconnections. The connector complies with international standards for electrical safety and environmental resilience. Widely adopted in B2B markets, it serves as a critical component in machinery control systems, sensor networks, and vehicle electronics. Its modular design allows for easy integration with existing wiring harnesses, reducing assembly time and maintenance costs.
Structure and Working Principle
The connector comprises a thermoplastic housing for insulation and metal contacts (typically gold-plated) for low-resistance conductivity. The M4 locking screw ensures a secure fit, even under vibration or mechanical stress. Female and male versions are available for inline or panel-mounted configurations. Electrical signals pass through the crimped or soldered contacts, which are shielded from external interference by the housing. The LF (Lead-Free) designation indicates compliance with RoHS environmental regulations, making it suitable for global supply chains.
Key Features
Durability stands out as a hallmark of the FVDWS1.25-M4(LF), with a rated mating cycle of 50+ insertions without performance degradation. Its IP67-rated variants resist dust and temporary water immersion, ideal for outdoor or washdown environments. Other features include color-coded housings for easy identification, a 3A current rating at 250V AC/DC, and an operating temperature range of -40°C to +105°C. These attributes make it a versatile choice for diverse industrial scenarios.
Application Areas
Primary applications include automotive ECU connections, robotic arm wiring, and PLC systems in factories. Its reliability is critical in safety-sensitive systems like brake sensors or aviation instrumentation. In renewable energy sectors, the connector links solar panel monitoring devices, while in medical equipment, it ensures noise-free data transmission for diagnostic machines. The compact size also benefits consumer electronics, such as drones and wearable devices.
Maintenance and Precautions
Regular inspections should check for contact corrosion or housing cracks, especially in high-humidity environments. Use compatible crimping tools to avoid wire damage during assembly. Avoid exposing non-IP-rated variants to liquids or excessive UV radiation. For threaded connections, apply a torque of 0.4–0.6 N·m to prevent overtightening, which may strip the threads or deform contacts.
B2B Procurement Guide
When sourcing FVDWS1.25-M4(LF), prioritize suppliers with ISO 9001 certification to guarantee quality consistency. Request samples to test fit and electrical performance with your specific cables. Bulk purchases (1,000+ units) typically reduce costs by 15–30%. Lead times vary from 2–6 weeks; expedited production may be available for urgent orders. Verify RoHS/REACH compliance documentation for EU market shipments.
