Linear magnetic encoders


New LM10 linear magnetic encoders "go long" - bringing 100 meter travel capability and fit-and-forget operating life to high-speed and high-precision positioning for industry's toughest machinery applications. The solid-state, non-contact design features a compact, IP68 readhead that rides at 0.1 to 1.5 mm standoff over a self-adhesive magnetic strip scale, providing the count for high-performance positioning - e.g. 5µm resolution at 20m/s and 1 µm at 4 m/s. Non-contact magnetic sensing delivers dependability in applications too dusty, dirty, greasy or destructive for optical encoders, while providing OEMs with major cost economies. Simple to install, the LM10 features integral setup LEDs on the readhead, wide installation tolerances, and an applicator tool for the adhesive-backed magnetic scale. The scale is available either "cut to length" or in lengths of up to 100 m in easy-to-handle coils. Engineered for extreme service, the solid-state LM10 linear encoders offer operating temperatures from -20°C to 85°C, water-proof sealing to IP68, and high resistance to shock, vibrations, and pressure. Non-contact, frictionless operation eliminates wear while reducing inertia for high precision at high speeds and acc/dec. The LM10 encoders bring lasting solutions to tough, hard-working applications - woodworking, stone-cutting, sawing, metalworking, textiles, packaging, paper and converting, plastics processing, automation and assembly systems, laser/flame/water-jet cutting, electronic chip/board production, etc. Offering great application versatility, the LM10 encoders come in digital or analog output models and offer customer-selectable resolutions including 1, 5, 10, 50 and 100 µm and user-selectable reference mark position. The LM10 delivers maximum velocity of 25 m/s for sinusoidal output, while digital models position at 25 m/s for outputs at 100, 50 and 10 µm resolution, 20 m/s at 5 µm resolution and 4 m/s at 1 µm. The new Renishaw linear encoders join a proven family of RLS magnetic rotary/angle encoders using Nobel Prize-winning Magneto Resistive technologies, chosen by OEMs worldwide for affordability and operating dependability. As with all Renishaw products, a worldwide application support network and local inventory stocking give confidence to system developers and OEM volume producers.m
