Frequently Asked Questions

1. What is the 1.8mm pitch connector best suited for?

The 1.8mm pitch is a space-saving intermediate pitch size optimally positioned between standard 2.0mm and fine-pitch 1.25mm connectors. It is widely used in industrial control boards, instrumentation, compact power supplies, and automation equipment where PCB real estate is limited but higher current capacity (2.0A – 2.5A) is still required.

2. What pin counts and mounting orientations are available?

This series offers 2P to 15P configurations in both Right-Angle (Horizontal) and Straight (Vertical) SMT mounting orientations. This flexibility allows engineers to select the optimal configuration for compact PCB layouts in diverse product designs.

3. What is the electrical rating?

Rated current is 2.0A – 2.5A AC/DC with a rated voltage of 125V AC/DC. The Phosphor Bronze contacts with Tin or Gold plating ensure low contact resistance and stable electrical performance across repeated mating cycles and environmental stress.

4. What is the operating temperature range?

The connector operates from -40°C to +105°C, covering industrial automation, automotive electronics, and telecommunications environments. The high-temperature thermoplastic housing (UL94V-0) withstands lead-free reflow soldering and provides dimensional stability across this range.

5. What contact materials and plating options are offered?

Contacts are made of Phosphor Bronze with Tin or Gold Plating options. Tin plating provides a cost-effective solution for standard applications, while gold plating offers superior corrosion resistance and higher mating cycle durability for demanding industrial and medical environments.

6. Is this connector optimized for automated SMT assembly?

Yes. The coplanarity and standardized geometry of the SMT design allow for precise automated pick-and-place assembly. The standardized footprints streamline manufacturing, and automated production with inline optical inspection ensures consistent quality across high-volume production runs.

7. What are the primary application areas?

Key applications include industrial automation (PLC systems, servo drives, industrial control boards), automotive electronics (in-vehicle infotainment, lighting systems, body electronics), telecom and data communications (network switches, routers, communication modules), consumer electronics (smart home appliances, handheld devices, drones), and medical and instrumentation (patient monitoring devices, precision measuring equipment).

8. What quality assurance processes apply to this connector?

Quality assurance includes electrical verification (contact resistance, insulation resistance, and dielectric withstanding voltage tests), environmental testing (thermal shock, humidity aging, salt spray resistance), and mechanical validation (insertion/extraction force profiling, cycle-life testing to ensure reliable mating retention).
