Robust solutions with safety certification
The extremely rugged incremental encoders FG 41 (solid shaft) / FGH 41 (hollow shaft) are specifically designed for safety applications in heavy industry. The SIL certified series offers a high level of safety up to SIL 2 / PL d (position oriented) and SIL 3 / PL e (speed oriented). The encoders are highly resistant to shock and vibration loads, with degree of protection up to IP67. Day offer a high signal quality (HTL, TTL, Sin/Cos) up to 4096 pulses to guarantee exact measurement results even in particularly harsh operating conditions such as in wet areas in rolling mills or sea air.
