Fraba Posital certified safety encoder
PCA’s Fraba Posital division has announced the addition of a certified safety encoder to its OCD series of absolute shaft encoders. The encoders offer increased personnel safety, minimal risk of machines malfunctioning and reduced costs, the company claims.
In addition to creating a safer environment, the transmission of ‘Safety Position’ eliminates the need to install two separate encoders, and the complex development of validation monitoring logic in the PLC.
The encoders fulfil the requirements of IEC 61508, EN 62061 (SIL CL3) and EN ISO 13849 (performance level e). Operated with protective extra low voltage (PELV), they are suitable for use in drive technology, lift applications, mobile machines, construction machinery, cranes and machine tools.
The OCD encoders use a proven optoelectronic method to measure absolute position values. The single-turn sensor provides a resolution of up to 16 bit/revolution (0.05°) and the multiturn unit registers a maximum of 16,384 revolutions (14 bit), thereby covering an overall measuring range of 30 bit. The encoders have two functional devices within the one physical housing.
