MEGATRON Family ETx25 ETx25 encoders - compact and versatile The encoders of the ETx25 series are specially designed where a high durability and an optimum adaptability of the sensors is important. The contactless encoders in the 025 mm glass fibre reinforced thermoplastic can be precisely matched to the respective area of application thanks to their numerous electronic and mechanical options. Whether as incremental or absolute value encoders, they cover a wide range of applications and, depending on the output electronics, are used in systems, laboratory devices and medical devices, for example....
