AND Junction Box AD4386-3

Explosion-Proof Junction Box with Signal Adjustment for Multi Load Cell Systems

The AND Junction Box AD4386-3 is a high-performance junction box engineered to safely and reliably connect multiple explosion-proof load cells in demanding industrial weighing systems. Designed for use in hazardous and harsh environments, this unit supports parallel connections for 2 to 4 pressure-resistant explosion-proof load cells, enabling accurate signal summation and stable system performance.

With an IP67-rated enclosure, the AD4386-3 is fully protected against dust ingress and water immersion, making it well suited for outdoor installations, washdown areas, and industrial sites exposed to moisture or contaminants. A built-in potentiometer allows individual load cell output adjustment, ensuring balanced signals and improved accuracy in multi-load-cell configurations. This makes the AD4386-3 an ideal peripheral component for explosion-proof weighing and force measurement systems where safety and precision are essential.
