The FOX rotary gear limit switch by TER is a mechanical upgrade over the more economical BASE unit. It features a larger shaft diameter, ball bearings for smoother rotation, and switches with a rated mechanical life of 10million operations. The shaft is typically attached to the shaft of a sprocket or gear in the drive train and as the FOX shaft turns, it turns the cams inside the switch according to the gear ratio. For 75:1 ratio, the FOX shaft turns 75 rotations for 1 complete rotation of the cams inside. Please note, the FOX uses “nominal” gear ratios for the description, if the actual ratio differs it is shown in the description in parenthesis. For highest accuracy, select a gear ratio that will use as much of the full 360° rotation of the cams as possible. Custom ratios are available. The FOX is rated IP67 and rated for ambient temperatures from -40°C to +80°C, making it suitable for the harshest environments. The FOX can be configured with gear ratios from 3:1 up to 2870:1 and can be configured with up to 6 switches each with NO/NC contacts. Standard shafts are made from AISI430F stainless steel with 12mm (1/2” diameter). Housing, and gears are made from techno-polymer. FOX limit switches are UL listed, CSA certified, and CE marked. We also carry mounting options like woodruff keys, pinions, and flanges. Contact Springer Controls for custom gear ratios and switch configurations.
