Olfeld’s Limit Switches are precision-engineered electromechanical devices designed to monitor the presence, position, or movement of objects in automated systems. Built for reliability and durability, these switches are essential components in machine safety, conveyor systems, lift controls, valve positioning, and industrial automation setups. Whether it’s detecting door closure or confirming the end of travel in a mechanical arm, our limit switches ensure accurate, repeatable feedback in real-time.

Our range includes rotary, plunger, roller-lever, and spring rod-type switches, all enclosed in robust metal or reinforced plastic housings to withstand harsh industrial environments. Engineered with IP65 to IP67 protection ratings, these switches are resistant to dust, oil, and water ingress—making them ideal for use in manufacturing plants, automotive lines, packaging machines, and heavy-duty machinery.

Each unit features snap-action or slow-break contacts with silver or gold-plated terminals to ensure long service life and secure signal transmission. The mechanical life of our limit switches exceeds 10 million operations, offering dependable operation in high-cycling applications. Optional adjustable actuators and modular contact blocks allow for flexible customization to suit any installation.

Safety is paramount—Olfeld’s limit switches comply with global standards like IEC, EN, and UL, and are available in standard, safety-rated, and explosion-proof variants. Designed for easy wiring, quick mounting, and maintenance-free operation, they seamlessly integrate into existing control systems and PLCs.

When it comes to precision and ruggedness, Olfeld Limit Switches deliver the perfect balance of performance and safety in any automation environment.
