Black Grey Brown Blue Sealable PCB Mount Header – Technical Description A Sealable PCB Mount Header is a high-performance interconnect component designed for secure and reliable printed circuit board (PCB) connections in demanding environments. Available in black, grey, brown, and blue housings, these headers provide both functional and aesthetic versatility while ensuring robust electrical and mechanical performance. Key Features 1. Sealable Design - The header features a sealable or IP-rated housing, protecting connections from dust, moisture, chemicals, and other contaminants. - Gaskets, overmolding, or tight-fitting shrouds ensure environmental resistance, making it suitable for industrial, automotive, and outdoor applications. 2. PCB Mount Configuration - Designed for through-hole (THT) or surface-mount (SMT) soldering, ensuring strong mechanical attachment to the PCB. - Pin spacing (pitch) options typically include 2.54mm (0.1"), 2.00mm, or 1.27mm, accommodating various PCB layouts. 3. Color-Coded Housings - Available in black, grey, brown, and blue, allowing for easy identification and organization in multi-connector systems. - Colors may indicate different pin counts, polarities, or voltage ratings for simplified assembly and maintenance. 4. Material & Durability - High-temperature thermoplastics (e.g., PA, PBT) for the housing ensure resistance to heat, UV, and mechanical stress. - Contacts are made from phosphor bronze or brass, often plated with gold or tin for low resistance and corrosion protection. 5. Polarization & Keying - Polarizing ribs, slots, or asymmetrical designs prevent mismating, ensuring correct connector alignment. - Some variants include locking mechanisms (latches, screws) for vibration-resistant connections. 6. Electrical Performance - Rated for voltage (250V–600V) and current (3A–10A) depending on pin size and material. - Low insertion force (LIF) or zero insertion force (ZIF) options available for delicate applications. Applications - Industrial Controls: PLCs, motor drives, and sensor interfaces. - Automotive Electronics: ECUs, lighting, and infotainment systems. - Outdoor Equipment: LED signage, solar inverters, and marine electronics. - Medical Devices: Sealed connections for diagnostic and portable equipment. Advantages - Reliability: Secure mating and environmental protection extend product lifespan. - Customization: Multiple pin counts (1–40+ pins) and colors for design flexibility. - Compliance: Meets industry standards (UL, IEC, RoHS) for safety and sustainability. In summary, sealable PCB mount headers in black, grey, brown, and blue offer a durable, organized, and environmentally resistant solution for modern electronic assemblies. Their robust construction and versatile design make them ideal for harsh or high-reliability applications.
