Oil Tight Limit Switches (LS-Series)
Essen deinki’s LS series of oil-tight limit switches are a solid choice for industrial use. They come with 1 Normally Open (NO) and 1 Normally Closed (NC) contacts, offering both normal and snap-action operation. Housed in a tough die-cast aluminium casing, these switches have IP65 protection, shielding them from harsh conditions. They’re built to go the distance, with a long lifespan both mechanically and electrically. Plus, there’s plenty of space for wiring, making installation a breeze. These switches meet the IEC 947-5-1 standard, ensuring they’re reliable and compatible in a variety of industrial setups. Essen deinki’s LS series is your reliable solution for demanding environments.
