Product Overview

This is a compact, space-saving double-deck (two-story) terminal block designed for reliable wire-to-board connections. Featuring a 3.5mm pin pitch and 90-degree right-angle bending, it allows for low-profile parallel mounting to the PCB. The unique double-layer design effectively doubles the wiring density while minimizing board space consumption. Integrated mounting ears (flanges) on both ends provide reinforced mechanical fixing, ensuring high vibration resistance and stable soldering.

9. TERMINAL BLOCK FAQ

Q1: What real-world benefits does the 3.5 mm double-row right-angle pin header with dual-side flange bring to cabinet hardware design?

Flanges let you screw it firmly onto PCBs or mounting brackets. Vibration inside control cabinets will not shake the header loose. Right-angle layout saves depth space inside compact device housings.

Q2: What wire and electrical parameters should I follow for this 3.5 mm double-row flanged right-angle header?

Standard pitch is 3.5 mm for double-row configurations. Typical working specs: 300 V, 8-10 A per pin under IEC and UL conditions. Match it with 0.5-1.5 mm² stranded or solid wires.

Q3: What common assembly mistakes happen with dual-side flange mounting during production?

Many teams over-tighten flange fixing screws, which warps PCB substrates or cracks the header plastic base. Keep moderate torque and ensure flat contact between the flange face and mounting surface.

Q4: Can I mix different-brand 3.5 mm double-row right-angle flanged headers in one cabinet project?

While 3.5mm is a standard pitch, pin thickness, spring force and flange dimension tolerances differ among manufacturers. Stick to matching pin header and plug sets from one supplier for mass production.

Q5: What checks should I perform for incoming parts and on-site commissioning of this flanged right-angle header?

Inspect pin straightness when parts arrive and verify flange holes align correctly. During commissioning, physically tug mated pairs lightly to confirm the flange absorbs pull force instead of solder joints taking all stress.
