Eddy current proximity sensors and switches detect the proximity or presence of a target by sensing the magnetic fields generated by a reference coil

Proximity sensors, all types is a general search form for all proximity sensors and presence detection product areas

Ultrasonic proximity sensors use reflected or transmitted ultrasonic waves to detect the presence or absence of a target component

Switches are devices that allow electric current to flow when closed and prevent current flow when opened. Switches, All Types are a high level search form that includes options for all switch types. Search forms for specific switch actuator types are also available

Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance

Magnetic proximity sensors include devices that work on inductive, variable reluctance, magneto resistive or Hall effect principles. Proximity sensors detect the presence or absence of an object using a critical distance

Capacitive proximity sensors detect the presence or proximity of a target using capacitive technology

Inductive proximity sensors detect the presence or absence of an object using a critical distance

Fiber optic proximity sensors use fiber optic technology to detect the proximity of target objects

Photoelectric sensors use emitters and receivers to detect the presence, absence, or distance of target objects.

Reed switches are magnetically actuated switches. They are typically manufactured with two ferromagnetic reeds (contact blades), which are sealed in a glass capsule. In the presence of a magnet, the blades (contacts) close. 

Rotary limit switches use physically-actuated levers to rotate a shaft and operate the contacts in a switch, making them change state

Linear limit switches are electromechanical devices that require physical contact between a target object and switch activator to make the contacts change state

Specialty or proprietary products and accessories related to switches

Safety sensor switches are placed in enclosures to prevent accidental contact with live electrical connections
