Information about Optical Sensors, Time of Flight

Optical time of flight position sensors and instruments determine displacement and distance by measuring the time it takes light to travel from the instrument to a target and back. These sensors can use either lasers or LEDs as light sources. LEDs are often less powerful than lasers, limiting their effective distance. However, because LEDs are relatively weak sources of light, they do not have safety classifications and can be used in different applications than lasers can. The lasers in these sensors can be safety class I, II or III devices.

Products & Services Related to Optical Sensors, Time of Flight

Cable Extension Linear Position Sensors

Cable extension linear position sensors are used to measure the movement and displacement of objects. A cable or wire is attached to an object, and as the object moves, the transducer produces an electrical signal proportional to the wire's linear extension.

Linear Position Sensors and Switches, Ultrasonic

Linear position sensors and switches, ultrasonic, are used for position and displacement sensing, using ultrasonic technology.

Linear Position Sensors, Capacitive

Capacitive linear position sensors are devices that sense position / displacement using capacitance technology.

Linear Position Sensors, Eddy Current

Eddy current linear position sensors detect the distance from a target by using magnetic fields generated by a reference and sensing coils.

Linear Position Sensors, Fiber Optic

Fiber optic linear position sensors use fiber optic technology to sense position and displacement.

Linear Position Sensors, LVDT

Linear variable differential transformer (LVDT) linear position sensors have a series of inductors in a hollow cylindrical shaft and a solid cylindrical core. These devices produce an electrical output proportional to the position of the core

Position Sensors, Optical Triangulation

Optical triangulation position sensors use reflected waves to pinpoint position and displacement.
