120A Rectangular Terminal Post – High-Current IP67 Waterproof Power Stud

120A Rectangular Terminal Post – High-Current IP67 Waterproof Power Stud

The Longyd 120A Rectangular Terminal Post is a premium-grade, high-current electrical connection solution designed for industrial automation, energy storage systems, E-bikes, and heavy-duty power distribution. Built to deliver safe and stable electrical paths under challenging conditions, this power stud features superior IP67 ingress protection and exceptional thermal resilience.

Product Architecture & Structural Variations

To accommodate various industrial wiring environments, this terminal post series is engineered in two distinctive model types, ensuring maximum flexibility for your cable management layouts:

• Type A (Horizontal Screw-Clamping): Features a horizontal cross-recessed pan-head screw mechanism integrated directly into the lower terminal body. Ideal for side-entry wire connections where vertical space is restricted.
• Type C (Vertical Threaded Stud): Features a heavy-duty axial threaded bolt design extending straight downward, locked securely with a hex nut and washer. Best suited for standard straight-through vertical lug and ring-terminal terminations.

120A Rectangular Terminal Post Technical Specifications & Material Data

Dimensional Integrity (Precision Engineering)

Every terminal post complies strictly with standardized engineering tolerances (±0.1mm) for effortless deployment into your pre-existing mounting plates:

• Front Elevation Profile: Protective cap envelope measures 38.9mm in width and 38.9mm in total height. Main body base height sits at 28.0mm.
• Mounting Footprint: Features a 24.36mm square flange flange layout. Center-to-center distance of the 4 mounting screw holes is exactly 19.8mm, utilizing Ø4.5mm screws. Main chassis panel cutout requirement is Ø16.0mm.
• Depth Clearance: Side cross-sectional length measures 42.15mm with a robust thread collar diameter of 17.56mm and an outer step diameter of 21.16mm.

Package Includes:

Each set comes complete with 1x Main Terminal Post Body, 1x Removable Rectangular Protective Slide-Cap, 1x Anti-vibration Rubber Sealing Gasket, and premium stainless steel installation bolts and matching hex nuts for instant assembly.

FAQ Section

Q1: What is the main structural difference between Type A and Type C models?

A1: The difference lies entirely in their bottom termination design. Type A uses a horizontal cross-recessed screw mechanism that clamps wires from the side. Type C uses a traditional vertical threaded stud projecting downwards, secured via standard washers and hex nuts. Choose Type A for tight vertical spacing and Type C for standard ring-lug stackings.

Q2: Can these terminal posts be used outdoors under rain or coastal environments?

A2: Yes, absolutely. The product is officially rated at IP67 waterproof grade. It includes a specialized custom rubber sealing flange gasket that prevents water and dust ingress through the panel cutout, paired with a slip-on rectangular insulation cap to shield the exposed front terminal from moisture splashes.

Q3: What does the UL94-V0 flame retardancy rating mean for my application?

A3: UL94-V0 is the highest standard for plastic flammability testing. It indicates that the premium plastic housing will self-extinguish within 10 seconds when subjected to a vertical flame test, and will not release any flaming drips. This ensures ultimate fire safety in high-load industrial or automotive settings.

Q4: What size of mounting hole is required on the installation panel?

A4: Based on the detailed structural engineering drawing, you need to prepare a central clearance hole of Ø16.0mm for the main terminal body step. The surrounding 4 mounting screw holes should have a square spacing pitch of 19.8mm, accommodating Ø4.5mm fastening screws.
