1 UNI EN ISO 9001 C R US MULTITURN ASOLUTE EAM PARALLEL - SSI ENCODERS Description of the PARALLEL multiturn absolute encoder The EAM range of parallel multiturn absolute encoders was studied for applications requiring high accuracy, also on extended linear development; they are available with resolution levels up to 13 bits and therefore 8192 PositionsTurn on the turn and with resolution levels of up to 12 bits, 4096 Positionsturn for turns. The robust mechanics and the different types of flanging mean that it can be used in a broad range of applications, guaranteeing correct operation, even in the most arduous conditions. This range of encoders is available with cable or connector output and as for the single turn, they can reach a level of protection up to IP66, depending on the model. The output configurations are both grey code and binary and the output electronics cover all fields of application being available in the NPN, NPN OPEN COLLECTOR, PNP and PUSH PULL formats. Description of the SSI multiturn absolute encoder The range of multi-turn absolute encoders with SSI format output, supply the data in this format, created by technology already introduced into the single turn. The use of this standard increases the efficacy of this type of encoder; this is because the amount of data of a multi-turn is much higher and the serial approach becomes an optimum solution to the growing number of wires. For this series in fact, the output data is formed by a 25 bit word, as the standard in which the useful bits are numerically proportional to the resolution chosen for the encoder. This type of transmission therefore considerably reduces the wiring problem, while maintaining the device performance the same. In this encoder range, the data connections are reduced, as for the single turn, to just four wires; one pair for the position code and one for the clock signal, both in differential logic. The mechanical components, above all the flanging available are highly diverse and capable of satisfying the most widely ranging demands. 23
