Turck is a world leader in sensors and automation technology.

This video clip features Turck's Rectangular Limit switch style proximity sensor with weld field immunity used in a industrial pick-and-place machine.

TURCK's linear inductive sensor operation is based on the RLC resistance inductance capacitance principle. Unlike potentiometric or magnetostrictive technologies, 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.

Superior to alternative technologies, Q-track sensors' innovative design, linearity and repeatability eliminate common performance failures experienced with other technology options. The RLC principle of operation used in the Q-track linear position sensor is highly immune to noise interference and is inherently weld field immune. Since the position element does not contain a magnet, it can be used in metal working applications because it will not attract ferrous debris, which would affect the operation of a magnetostrictive sensor. Additionally, the inductively coupled position element provides non-contact position feedback ideal for use in applications with constant motion, such as pinch rollers, cylinder position, web tension control, pitch control, resisting damage and costly downtime.

Turck is a global leader in factory RFID technology and solutions. Typically, a plant's efficiency is highly dependent on the maximum possible speed of the transport equipment. While many conventional RFID systems allow only static read and write operations, the new BL ident system from TURCK is capable of reading and writing at all times. Data can be exchanged even when the data carrier is in motion. With a read-write time of 0.5 ms per byte, BL ident is one of the fastest inductive RFID systems on the market. Even transport speeds of over 10 ms are achievable.

BL ident is available with 2, 4, 6 or 8-channels. BL ident systems may be integrated into existing systems, including PROFIBUS-DP, DeviceNet, Modbus-TCP, ROFINET, and EtherNet/IP. All while providing IP 20 or IP 67 protection.

BL ident data carriers are available with a temperature resistance of up to 210°C (410°F), for 30 minutes in addition to standard data carriers for temperatures up to 120°C (248°F).

Use of state-of-the-art FRAM storage technology allows 1010 write operations and an unlimited number of read operations on TURCK data carriers. This makes replacing data carriers practically unnecessary; even when used in applications requiring repeated write operations. This dramatically increases the availability of the equipment. And all data remains stored on the data carriers for 10 years (at appropriate ambient temperatures).
