1. Overview of the TTK70 Linear Encoder SICK

The TTK70 is an absolute magnetic linear encoder from SICK AG, designed for precise linear position measurement and speed feedback in linear drive systems. The system consists of two main components: the read head and the magnetic tape. Thanks to its non-contact measuring principle, the encoder operates reliably without mechanical wear. It features two parallel tracks on the magnetic tape (incremental + absolute), enabling true absolute position detection right after power is applied – no homing or reference run is needed. The HIPERFACE versions (including the safety-rated TTK70S) are certified to SIL2 and PL d, making them suitable for integration into safety-related drive systems according to IEC 61508 and EN ISO 13849-1. In practice, the TTK70 serves as an excellent alternative to optical linear scales in environments with dust, oil, or condensation. Highlight Specifications:

3. Industrial Applications of the TTK70 Linear Encoder

In real-world factory environments, linear drive systems often demand high accuracy while operating in conditions with dust, oil, or vibration. This is why magnetic encoders like the TTK70 are increasingly preferred. With absolute position measurement at 1 µm resolution and travel speeds up to 10 m/s, the TTK70 is well-suited for applications requiring precise positioning:

Linear Motors: Linear motor axes achieve high speeds and require real-time position feedback. The TTK70 with HIPERFACE interface provides Sin/Cos 1 Vpp signals for servo drives, ensuring stable closed-loop speed and position control while eliminating accumulated errors common in incremental encoders.
Pick & Place Systems and Gantry Robots: In SMT pick-and-place machines, gantry robots, and CNC portals, the TTK70 delivers absolute position immediately after power-up – no reference travel is needed, significantly reducing machine startup time. The ±10 µm system accuracy meets the requirements of electronics assembly and precision metalworking.
Harsh Industrial Environments: The TTK70 magnetic tape performs reliably in the presence of dust, oil, and condensation – conditions where optical scales often fail. With IP67 protection and high shock/vibration resistance, it ensures dependable operation in steel rolling mills, stamping presses, and automotive painting lines.
Safety-Related Drive Systems: The TTK70S version (with safety functionality and SIL2/PL d certification) is ideal for applications requiring safe position monitoring, such as safety doors, collaborative robot arms, and hydraulic presses – where position feedback failure could result in serious workplace accidents.

4. Comparison of TTK70 Versions – Which Model to Choose?

Rotary encoders measure rotary motion and require mechanical conversion (ball screw, rack & pinion, etc.) to determine linear position. This can introduce mechanical backlash and cumulative errors over time. In contrast, the TTK70 measures position directly on the moving axis without intermediate mechanics, eliminating mechanical errors and delivering superior accuracy and repeatability. The TTK70 is available in two main interface groups – HIPERFACE and SSI – plus the safety-rated TTK70S variant. The table below helps you select the right model quickly:

Criteria	TTK70 HIPERFACE	TTK70 SSI
Primary interface	HIPERFACE + Sin/Cos	SSI
Connection	M12, 8-pin	M12, 12-pin
Safety certification	SIL2 / PL d (TTK70S version)	None
Best suited for	Servo drives, safety systems	PLCs, digital position control
Real-time feedback	Sin/Cos 1 Vpp (instant response)	SSI clock-based

Recommendation: Choose the TTK70S HIPERFACE version if your application requires real-time speed control and integration into safety systems. Select the standard TTK70 SSI version if you only need straightforward PLC connectivity and want to optimize cost.

Frequently Asked Questions (FAQ) about the TTK70 Linear Encoder

Q1: In which industries is the TTK70 commonly used? A: The TTK70 is typically used in systems requiring high-precision linear position measurement, such as linear motors, SMT pick-and-place machines, gantry robots, CNC machines, automotive assembly lines, and other linear drive applications. Q2: Does the TTK70 come with a warranty? How long is it? A: The product usually includes the manufacturer’s standard warranty. Warranty duration may vary depending on the supplier and purchase conditions. Q3: What is the difference between the TTK70 and a rotary encoder? A: A rotary encoder measures rotary motion and requires mechanical conversion to determine linear position, which can lead to cumulative errors. The TTK70 is a true linear encoder that measures position directly on the linear axis, providing higher accuracy and repeatability – especially suitable for applications demanding precise positioning. Q4: How much does the TTK70 linear encoder cost? A: The price depends on the specific configuration, including interface type (HIPERFACE®, SSI, or safety version), measuring length, and accessories. Please provide your application requirements for an accurate quotation. Q5: Where can I buy genuine TTK70 linear encoders in Vietnam?
