Optical hollow shaft encoder with up to 50 millimeter bore
The optical hollow shaft encoder FGH 6 is supplied with a large hollow shaft bore up to 50 millimeters in size. The stable, ribbed cast aluminium design and the flat style of construction ensure the encoder is particularly suitable for fitting other devices such as speed switches and absolute encoders or combinations of both. The device is available with radial shaft seals and high protection class rating up to IP56 (IP66) for use in permanently oily/wet environments. The precision nickel pulse disk offers up to 4096 pulses; the electronics are integrated in the encoder or rather the replaceable scanning head. A redundant version is available with two identical scanning and evaluation electronics. The encoder is insensitive to the effects of mechanical stress factors such as vibration, axial bearing play and thermal expansion.
