Rugged Junction Box for Precise Load Cell Trimming

The JB8SP TuffSeal® is built to handle tough environments where multiple load cells need to be trimmed and protected. Designed for truck, livestock, and railroad scales, this rugged NEMA Type 4X junction box offers exceptional protection with its polycarbonate enclosure, PreVent™ breather vent, and conformal coated circuit board.

Supporting two to eight load cells (even numbers only), the JB8SP makes setup easy with pluggable connectors and precise individual cell and section trimming. Its expansion port adds versatility for future system growth, and the removable connectors simplify service and replacements.

Key Features

  • Durable Polycarbonate Enclosure
    Seals out dust, moisture, and debris for reliable outdoor operation.

  • PreVent™ Breather Vent
    Reduces internal condensation by equalizing pressure during temperature changes.

  • Signal Trimming Options
    Offers both individual cell and range (section) trim capability.

  • Tool-Free Maintenance
    Easily service load cells using removable screw-type connectors.

  • Conformal Coated Circuit Board
    Adds an extra layer of protection to sensitive electronics in harsh conditions.

Applications

  • Truck Scales

  • Livestock Weighing Systems

  • Railroad Track Scales
