This is a stainless steel load cell junction box, specifically a JXB-10 10-channel model designed for industrial weighing applications.
It features a green circuit board with spring clamp terminals for balancing multiple analog load cells and summing their signals into a single output.
The enclosure is designed for protection, typically meeting an IP67 rating to be waterproof and suitable for harsh environments.
Included cable glands are used to secure and waterproof the incoming load cell cables and the outgoing signal cable.
