Limit Switches

Reliable Motion Control & Safety Sensing for Industrial Machinery

Maximize operational precision and safety with high-performance industrial limit switches from Kent Electrical Supply. Designed to detect the presence, absence, or position of objects through physical contact, our limit switches are essential for conveyor systems, elevators, and automated manufacturing lines. Whether you are replacing a heavy-duty NEMA limit switch or seeking a compact IEC-rated solution, we stock a vast inventory of actuators and switch bodies to meet your exact specifications.

Shop Top Brands: Lovato, Eaton, Schneider & More

We are authorized distributors of the industry’s most durable sensing brands. Our catalog includes:

  • Lovato Electric: Specializing in the KC and KM series, offering modular designs with various contact configurations (1NO+1NC, 2NC) and robust metal or plastic housings.
  • Eaton / Cutler-Hammer: Industry-standard E50 and 10316 series limit switches, known for their modular "plug-in" design and high environmental resistance.
  • Schneider Electric (Telemecanique): Featuring the world-renowned OsiSense XC range, perfect for everything from light-duty automation to severe-duty applications.
  • Allen-Bradley & Siemens: Precision-engineered 802T and 3SE series switches for critical machine tool and safety-related positioning.

Limit Switch Actuator Types & Applications

The right actuator is determined by the direction and speed of the object being detected. Explore our selection of:

  • Side Rotary Levers: The most versatile type, featuring adjustable roller levers for cam or slide actuation. Available in fixed length and adjustable rod styles.
  • Top & Side Plungers: Ideal for short-stroke linear motion detection where mounting space is restricted. Choose roller plungers for horizontal movement.
  • Wobble Sticks & Cat Whiskers: Flexible rod actuators that can be triggered from any direction—perfect for counting irregularly shaped objects on conveyors.
  • Rotary Limit Switches: Specialized for cranes, hoists, and rotating equipment to control travel limits based on shaft revolutions.

Rugged Performance for Harsh Environments

Our sealed limit switches are built to withstand the rigors of the factory floor:

  • IP65, IP67 & NEMA 4/4X/13: Protection against oil, water, dust, and coolant seepage.
  • Snap-Action Contacts: Ensures rapid, repeatable switching regardless of the actuator speed, preventing arcing and extending electrical life.
  • Positive Opening Mechanism: Essential for safety-critical applications (E-stop circuits), ensuring the contacts physically separate even in the event of mechanical failure.
