The SB142 standard size, fiberglass switch box is used to convert the three-conductor input wiring of up to eight remotely installed dual-output accelerometers or piezo velocity sensors to two switched BNC connectors and one switched two-pin MIL spec connector for portable data collection. Input wiring from each sensor is connected to the outputs via spring cage or screw terminal blocks. Each terminal block includes inputs for signal, temperature, 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 SB142 comes equipped with built-in online expansion jacks. To utilize this feature, simply purchase JB905-1A (12 position, spring cage plug) or JB905-2A (12 position, screw terminal plug) and connect your output wiring for continuous, live readings. Please note, JB905-1A and JB905-2A are sold separately. One JB905-1A or JB905-2A plug is required per six channels of measurement.
Rated for NEMA 4X (IP66), the SB142 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. A snap latch is installed on the door allowing the box to be sealed from the elements when not in use.
