1 TURCK Linear Displacement Transducers TURCK introduces a new line of linear displacement transducers (LDTs) called EZ-Track. EZ-Track is the latest offering in TURCK s continuous effort to change the shape of sensing. Based on magnetostrictive technology, the EZ-Track line will reliably operate in the harsh conditions for which TURCK products are known. With its unique features, IP 67 environmental rating, 4 to 180 inch measurement span and absolute positioning, the EZ-Track line will be sure to fit into your tough linear sensing applications. Features and Benefits Non-Contact Sensing Reduces Wear, Breakage, Downtime, and Ultimately, Cost The Q21 Series from TURCK is a line of magnetostrictive linear displacement transducers. These non-contact devices detect the position of an external magnet along the active stroke of the sensor without causing any wear on the sensor parts. Because there are no parts to wear or break, the sensors can offer better performance over a longer life than competing technologies. They offer an alternative when a continuous, absolute reading is necessary in the application. The absolute reading allows the sensor to accurately know the position at power on without the need to set up a home position. With this technology, an accuracy of +/- 0.1% of the stroke and a repeatability of +/- 0.01% of full stroke can be achieved. Fast Connections As a leading supplier of connection products, TURCK delivers the complete package. Standard, shielded 4-pin, M12x1 eurofast cables are always available from TURCK for quick connection to EZ-Track. Reliable Accurate Technology Magnetostrictive technology is when a mechanical impulse is applied to the magnetostrictive waveguide that travels the length of the sensor. The traveling pulse encounters the magnetic field produced by the slide or floating magnet assembly. The interaction of the mechanical pulse with the magnetic field produces a current pulse that is picked up by the electronic circuitry. A high speed timer measures the time between the applied mechanical pulse and the induced current pulse. This time, proportional to position, is compared to the zero and span positions established during the calibration process to scale the output. Once the position has been scaled accordingly, it is converted to an analog signal in the form of a voltage or current output. Thus giving you highly accurate, non-contact position sensing with absolutely no wear on the sensing element.

2 Low Profile Extrusion Housing Low Profile Housings Reduce Mounting Restrictions and Eliminate Special Mounting Fixtures The Q21 Series are housed in low profile, environmentally sealed, anodized aluminum housings. The electronics and the sensing element are incorporated into a housing that is less than 1 inch tall without the need for a can or head on the sensor to house the electronics (typical competitive devices are 2.5 times larger). By reducing the profile of the sensor, less thought has to be put into the mounting of the sensor. The Q21 Series will fit into applications where others are too bulky. Diagnostic LED An LED Indicating the Status of the Sensor Simplifies Troubleshooting and Reduces Maintenance The Q21 Series utilizes a diagnostic LED that enables the operator to understand the state of the sensor dependent upon the position of the target magnet. The LED is green when the power is on and the magnet is in an active programmed area. The LED turns yellow when the magnet moves out of the programmed area, but is still within the active stroke. The LED turns red when there is no magnet present or it is in the null or dead zones. This feature simplifies programming and troubleshooting, effectively reducing setup and maintenance time. IP 67 The Q21 Series will stand up in the harsh environments for which TURCK products are known. Downtime situations due to environmental conditions can be reduced.

3 Programable Stroke Programmable Zero and Span Allow Standard Sensors to Have Customized Stroke Lengths, Eliminating the Need to Stock Numerous Models The analog output of the Q21 Series is not limited to the entire length of the sensor. The zero and span settings can be programmed anywhere along its active stroke. By utilizing this feature, the user can reduce stock of the various length LDTs used in the plant by replacing them with standard sizes and programming to the specific applications. Stroke lengths are available from 4 to 180 inches. To Program the EZ-Track Sensor: 1 inch Zero setting 30 inch Span setting Short pin 2 to pin 3 to obtain Zero setting and short pin 2 to pin 1 to obtain Span setting or use TURCK s TB-LDT Programmer. 3 inch Zero setting Null Zone 3 inches 3 Foot Stroke Dead Zone 1.5 inches 26 inch Span setting Dead Zone 1.5 inches Null Zone 3 inches 3 Foot Stroke Note: When ordering a sensor, total length will be 4.5 longer to accommodate the null and dead zones. Example: LT36E will be 40.5 in total length. Various Outputs Available The Q21 Series can be ordered in a variety of analog outputs. Voltage: Current: 0 to 10 V 4 to 20 ma 10 to 0 V 20 to 4 ma 10 to 10 V 10 to 10 V Although sensors can be ordered with any of the above outputs, the units can easily be changed in the field to reverse the analog signal. Thus, one model can be used for two applications by programming the zero and span appropriately. For Quadrature outputs, consult factory.
