The ANYLOAD J04EA-16 and J04SA-16 J-Boxer Junction Boxes are compact aluminum enclosures designed to sum and trim 2 to 4 single load cells within an industrial weighing system. Built with a strong aluminum casting and rated IP67, the J-Boxer protects load cell wiring and calibration components in harsh plant, outdoor, and washdown environments while keeping the system easy to service in the field.
Each junction box is fitted with independent potentiometers for individual cell trimming, giving technicians precise control over excitation or signal output on a per-cell basis. This makes it straightforward to balance multi-cell systems such as tank scales, hopper scales, and platform scales during commissioning or recalibration. A preinstalled GORE® breather vent equalizes internal pressure and helps prevent moisture ingress, supporting stable signal performance over time, while captive stainless steel screws stay attached to the cover to reduce lost hardware during maintenance.
The enclosure accepts M16 cable fittings sized for 4mm to 8mm diameter cable on both the input and output sides, accommodating a range of load cell and system cabling configurations. Two trimming configurations are available: the J04EA-16 for excitation trim and the J04SA-16 for signal trim, allowing the junction box to be matched to the load cell resistance and calibration approach used in the application. ATEX, FM, and IECEx approved versions carry the “-Ex” suffix for use in hazardous area installations.
If your project requires a junction box for summing multiple load cells or for use in a hazardous area, ANYLOAD can help you select the correct trimming configuration and certification. We work with system integrators and scale manufacturers to specify junction boxes suited to specific load cell counts, cable routing, and safety requirements.
