The ECH381R-04P is a 4-position, single-level PCB terminal block header with a 3.81mm pitch from Dinkle Corporation. It features a right-angle orientation and through-hole mounting with wave soldering termination. The header is rated for 300V/8A under UL/CUL Group B and D, and 320V/14A under IEC standards. Rated impulse voltage is 2.5kV and insulation resistance is ≥500MΩ at 500V DC.
The insulation material is polyamide (PA) with a UL94 V0 flame retardant rating, ensuring reliable operation in demanding environments. The operating temperature range is -40°C to 120°C. The contacts are made of copper alloy with tin plating, and the header includes finger protection for added safety. PCB hole diameter is 1.2~1.3mm and pin dimensions are 0.8x0.8mm.
Designed for use in industrial control, building automation, and power supply applications, this header provides a secure and compact connection solution. The 3.81mm pitch allows for high-density wiring while maintaining adequate creepage and clearance distances.
