The heavy-duty limit switches (HDLS) are the world's most advanced line of micro switches and are designed to withstand seismic shock. These switches include boss-and-socket head design for secure head-to-body retention and unique all-metal drive train for consistent operating characteristics even at high temperature. They are generally used in machine tools, material handling, packaging, presses, pulp and paper, welding, and PLC interface.</p><p>LSA3K-1B Limit Switch from Honeywell offers wide variety of operating heads and field adjustable operating modes for reduced inventory.
