Switch Boxes - Series 691B4x

Request Info 

• Switch boxes offer a simple, economical, and safe method for accessing up to 48 sensors that are installed in remote locations. 

• Each features a wall mountable, composite NEMA-4X (IP66) enclosure, internal terminal strip(s) for connection to pigtailed sensor cables, sensor location index chart, internal rotary selector switch(es), and internally mounted BNC jack connectors for interface to data collection equipment. Switch boxes do not supply sensor excitation power.

• Simply open the enclosure door, connect a data collector with sensor excitation power to the BNC jack for the bank of sensor channels of interest, and position the selector switch in the appropriate position to access individual sensor measurement signals. Optional painted steel NEMA-12 (IP-65) and stainless steel NEMA-4X (IP66) enclosures are also available.
