Limit switchbox for high temperature applications

Written by: Tom Austin-Morgan | Published:

Soldo Controls 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 LSB 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 are said to 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 access to switches and terminals, and rugged enclosure coatings for challenging environments. Ceramic terminals and special wiring options complete the compact Soldo design.

The range is tested at 250Vac 5A and has a guaranteed mechanical life of 1million cycles.
