SB242: Stainless Steel Switch Box

The SB242 standard size, stainless steel switch box is used to convert the three-conductor input wiring of up to 8 remotely installed dual-output accelerometers or piezo velocity sensors to a 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 the stainless steel enclosure. Additionally, the SB242 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 SB242 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 twist lock is installed on the door allowing the box to be sealed from the elements when not in use.
