Mechanical Design: The header features straight (vertical) pins designed for perpendicular mounting to the PCB. The pins are typically square in cross-section (often 0.64mm or 1.0mm square) to ensure a secure and gas-tight connection with standard female housings or crimp terminals. They are available in various circuit sizes, ranging from 4 to 40 pins (2x2 to 2x20).
Construction: Manufactured with a high-temperature resistant thermoplastic insulator (UL94V-0 rated) and phosphor bronze or brass contacts. The contact surface is typically finished with a tin plating for solderability and corrosion resistance, or optional gold flash for higher reliability in signal-level applications.

9.TERMINAL BLOCK FAQ
Q1: What are the core benefits of 3.5mm dual-row straight pin terminal blocks for industrial PCB design?
A: The 3.5mm dual-row straight pin design balances compact size and wiring capacity perfectly. It doubles connection points compared with single-row terminals in the same PCB area. Straight vertical pins support standard through-hole soldering. This layout simplifies board layout and keeps wiring neat, which is ideal for standardized control cabinet mass production.
Q2: Is 3.5mm dual-row straight pin structure stable enough for long-term industrial vibration environments?
A: Yes, industrial-grade dual-row straight pin terminals offer solid structural stability. The pins adopt integral rivet and knurled fixing technology. They will not loosen or tilt during wave soldering. In actual field operation, this rigid through-hole structure resists daily equipment vibration far better than SMD terminals, avoiding poor contact faults.
Q3: Will dense dual-row 3.5mm pin arrangement cause insulation or crosstalk issues?
A: No. Standard 3.5mm pitch is a mature industrial specification. It reserves sufficient creepage distance and electrical clearance. Professional terminal housings are equipped with independent barrier insulation. Even with dual-row dense wiring, it effectively isolates power and signal circuits, preventing crosstalk and short-circuit risks for regular low-voltage industrial equipment.
Q4: Are 3.5mm dual-row straight pin terminal blocks compatible with standard automated soldering processes?
A: Fully compatible. These straight pins feature high coplanarity design. It ensures every pin fits PCB through holes evenly during assembly. Made of high-temperature flame-retardant PA66 housing and tin-plated copper pins, they perfectly adapt to wave soldering and manual soldering. It greatly reduces defective soldering rates in batch production.
Q5: What industrial scenarios are the best fit for 3.5mm dual-row straight pin terminal blocks?
A: They are widely used in medium-density PCB control equipment. Typical scenarios include small PLC modules, building automation controllers, sensor acquisition boards, and general industrial control panels. The 3.5mm pitch is more space-saving than 5.0mm terminals, making it the cost-effective choice for compact industrial devices with moderate wiring demands.
