Potential sources causing interference.
Permissible bending radius for standard cables. When using multiturn encoders in electromagnetic fieldsgreater than 30 mT, please consult Leine & Linde.Both the cable shielding, the metal housings of encodersand subsequent electronics have a shielding function. It isrecommended that the housings have the same potentialand are connected to the main signal ground over the
machine chassis or by means of a separate potential comp-ensating line. Potential compensating lines should have aminimum cross section of 6 mm >
2 (Cu). >
The permissible cable lengths listed apply only for Leine &Linde cables and the recommended input circuitry of the
subsequent electronics.The cable type is normally polyurethane, PUR cables orPVC depending on encoder model. PUR cables are resistant
to oil, hydrolysis and microbes in accordance with VDE0472 and most cables comply with UL safety directives.Standard Leine & Linde cables can be used in a rigidconfiguration between 40 to 85ְC and in frequent flexingbetween 10 to 85ְC. High-temperature cables are avail-able upon request and shall be used when the permissibletemperature of the encoder exceed 85C. >
The permissible bending radius R depends on the cabletype, the configuration (flexible or rigid installation) andsurrounding temperature. Normative values for standardcables are shown in the picture below. >
