Turck Q25 high-speed inductive linear sensors

The Turck Q25 high-speed inductive linear sensor has a user-selectable internal measuring frequency up to 5 kHz, resulting in accurate measuring speeds of up to 5 m/s. They do not require a magnetic position device and are unaffected by metal debris commonly found in many industrial applications. The sensors provide high resolution and can be used to accurately measure lengths up to 1 m.

Turck’s linear inductive sensor operation is based on the RLC resistance inductance capacitance principle in which the sensors incorporate precisely manufactured printed emitter and receiver coil systems. The emitter coils are activated with a high-frequency AC field and produce an inductive RLC circuit with the positioning element. The element is inductively coupled with the receiver coils, which are arranged so different voltages are induced in the coils, depending on the position of the actuator. The voltages serve as a measure for the sensor signal. Q-track sensors deliver maximum measuring spans, with minimal blind zone and high resistance to EMI/RFI noise interference.

The high-speed integrated processor converts the signals into a 25-bit Gray code SSI signal which can be connected by an 8-pin M12 connection. Turck offers the Q25 in 10 standard measuring lengths starting at 100 mm with 100 mm increments up to 1 m. The Q25 has short blind zones of only 29 mm on each side, is IP67 rated and has a wide operating temperature range of -25 to 70°C.
