Description
EJB / ESB Junction & Switch Box Series
The EJB / ESB Series Junction and Switch Boxes are designed to connect and selectively switch multiple sensor inputs to a readout unit or data logger through a single output cable. These rugged, field-proven enclosures simplify multi-sensor monitoring setups, reduce cable clutter, and provide an efficient interface for data collection in geotechnical, structural, and environmental applications.
Each box accommodates several 4-core or multi-core input cables and includes switching functionality that allows operators to manually select and read individual sensors without disconnecting cables. The enclosures are sealed, corrosion-resistant, and weatherproof, ensuring reliable operation under field conditions.
Custom versions are available to support various numbers of sensors, cable types, and connector sizes.
