New Soldo switchbox for high temperature applications

Soldo Controls, a specialist manufacturer of position feedback devices in the Rotork Instruments Division, has introduced a high temperature extension to its LSB range of compact limit switchboxes for valves and dampers.

Manufactured with an aluminium or stainless steel enclosure, the new switchbox has been tested for operation in temperatures up to 250°C for 2 hours or 300°C for 70 minutes.

High temperature applications include tunnel ventilation dampers, HVAC plant rooms, and other building services environments.

Teflon-coated stainless steel bushings ensure smooth and low friction shaft rotation, whilst precision end-of-travel switches guarantee normally open and normally closed logics.

Standard features also include the Soldo twin shaft design, enabling easy access to switches and terminals, and rugged enclosure coatings for challenging environments.

The design also includes ceramic terminals and special wiring options.

The range is tested at 250VAC 5A and has a guaranteed mechanical life of one million cycles.
