JB110: Premium Fiberglass Switch Box, Extended Capacity

The JB110 extended capacity, premium fiberglass switch box is used to convert the two-conductor input wiring of up to 48 remotely installed single-axis accelerometers or piezo velocity sensors to a switched BNC and a switched two-pin MIL spec connector for data collection. JB Series enclosures are designed to have field input cabling installed behind the board. A flip-down panel allows the user to wire connections on location. Input wiring from each sensor is connected to the outputs via spring cage or screw terminal blocks. Each terminal block includes inputs for positive, negative and shield. The shield drain wire is earth grounded via a ground stud that is mounted to the side of the fiberglass enclosure. Additionally, the JB Series can be equipped with online expansion terminal strips, which can be selected upon ordering. The JB Series also features an IEPE bias indicator light built into the box itself, which can be used to indicate errors in the field wiring of the sensor.

Rated for NEMA 4X (IP66), the JB110 can withstand harsh environments including temperatures ranging from -58 to 180 °F (-50 to 82 °C). The box is also resistant to hose directed fluid and corrosion. Two snap latches are installed on the door allowing the box to be sealed from the elements when not in use.
