Encoders are usually used in fields such as industrial automation, robotics, and numerically controlled machine tools to transmit position and speed signals. The function of the extension cable is to connect the encoder and the controller, and it may be used in long-distance or complex environments.
How to solve the problem of signal loss or jitter?
TEONLE Tongle cables are equipped with a double shielding structure (aluminum foil + braided copper mesh, with a shielding coverage rate of ≥ 85%) and a differential twisted pair design, which can effectively suppress electromagnetic interference. If there is an abnormal signal, it is recommended to first check whether the grounding of the cable shielding layer is good, and at the same time, avoid running parallel to the power cables. When the cable length exceeds the recommended value (for example, the TTL/HTL signal of the incremental encoder exceeds 100 meters), a signal repeater or optical fiber converter can be installed to ensure stable signal transmission.
How to select the cable specifications for different encoders?
Incremental encoders: It is necessary to match the HTL/TTL/RS422 signal type and voltage (5V/24V). A twisted pair shielded cable with low capacitance (≤100pF/m) is recommended to ensure that high-speed pulse signals above 1MHz have no distortion.
Absolute encoders: Support protocols such as SSI, BISS-C, and PROFINET. It is recommended to use a dedicated cable of ≤ 50 meters, and match it with gold-plated connectors such as Hirose HR10 and M12.
II. Application Problems in Harsh Environments
Which cable should be selected for high-temperature and oily environments?
High-temperature scenarios: High-temperature resistant PUR or silicone sheath, with an operating temperature range of -65°C to +180°C.
Oily/chemical environments: The PUR material is oil-resistant and corrosion-resistant, and can resist the erosion of engine oil and coolant.
Outdoor scenarios: IP68 protection level + anti-ultraviolet design, resistant to UV and ozone.
How to avoid cable damage in frequently moving scenarios?
Tongle has launched a dedicated high-flexibility cable for drag chains (with a bending life of ≥ 15 million times), which is suitable for high-frequency movement scenarios such as robot joints. The connector adopts a design with a locking nut or thread fixing to prevent loosening and falling off.
III. Selection and Installation Problems
How to ensure interface compatibility?
Tongle provides a rich variety of connector types, including M5/M8/M12 circular interfaces (4-8 pins), aviation plugs such as Hirose HR10, etc. The gold-plated contact design improves conductivity and oxidation resistance. You can contact the Tongle technical team to obtain a customized solution.
Do the cables meet the safety standards?
Tongle cables have passed UL, CE, and RoHS certifications, and meet the UL VW-1 or IEC 60332-1 flame retardant grade to ensure the safety of the industrial environment.
How about the installation convenience?
The cables use international standard color codes (such as A+/A-, B+/B-), and the pre-installed connectors support plug-and-play, which significantly reduces the wiring error rate.
