Limit/Interlock Switches

Omron heavy-duty limit switches are used to monitor the travel limits of a certain device by activating or deactivating the power supply to machinery. These switches feature well-engineered construction to withstand shocks and vibrations, as well as allow the proper functioning of electrical equipment in a wide range of temperatures. They are designed in accordance with UL and NEMA 3, 4, 4X, 6P, 12, 13 rated standards for use in hazardous locations. The double seal and the complete gasket cover on the head of these switches prevent the ingress of contaminants.

Dayton heavy duty limit switches are used to activate or deactivate power when travel limits are exceeded. These switches feature actuator assemblies capable of being rotated in 90 degree increments and interchangeable heads for smooth operation. They are equipped with screw terminals to allow easy wiring configuration and are capable of withstanding operating temperatures ranging from -20 to 185 degrees F. These units have NEMA 3, 4, 4X, 6P & 13 rated enclosure for protection from the ingress of contaminants, oil or non-corrosive coolants. They are available in depths of 1.76, 2.52 & 2.72 inches.

Dayton enclosed limit switches are designed for detecting the positioning, passing and presence / absence of objects in industrial operations. These electromechanical devices feature an actuator that senses an object coming in contact with the limit switch and instantaneously closes or open the electrical connection. They are integrated with screw terminals to allow easy wiring configuration and are capable of withstanding operating temperatures ranging from -14 to 176 degrees F. These units come with NEMA 1, 3, 4 and 13 rated enclosures for protection against ingress of contaminants, oil or non-corrosive coolant and accidental contact with the electrical equipment. Choose from a wide range of these contact sensing devices, available in plunger, wobbles stick and rotary lever arm style actuator options.

Dayton miniature precision limit switches to detect the presence or absence of objects in industrial applications. These units feature metal housing for use in rugged environments, roller lever / plunger actuator to signal the contacts for opening / closing the electrical connection when they detect an object (target), and screw terminals to allow easy wiring configuration. They meet 1P67 protection against dust, dirt and other contaminants and are ideal for low temperature applications ranging from -14 to 158 degrees F. Choose from an array of these micro limit switches, available in 2.11, 2.18 and 2.41 inch heights.
