We offer a range of magnetic linear and rotary encoders ideal for machine tools used within the hobby and model engineering workshops. This type of encoder offers a very compact profile size making it ideal for space restrictions on smaller machine tools or on the lathe cross slide.
The magnetic encoders consist of a reading head and precision pitched magnetized tape. This is made up of a chemical resistant rubberised material bonded to a stainless steel strip which has an adhesive backing. Making the magnetic tape flexible, this can be mounted directly to the machine surface or housed within an extrusion.
There is no contact between the reading head and magnetic tape, allowing for the electronics to be fully sealed making this type of encoder suitable for the harsh workshop environment. There are two types of extrusion setups available. An open type where the reading head and tape are installed as separate parts or an enclosed type where the reading head is enclosed within the extrusion, this makes mounting the same as the optical type encoders. The open type offers the smaller profile but can have a cover fitted to provide further protection from knocks and swarf.
Please feel free to contact our technical staff for further advice, or to arrange an on-site install by one of our engineers (UK only).
