Renishaw Intros Linear Encoder
Linear encoder.
Hoffman Estates, IL — 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 uses a compact, IP68 readhead that rides at 0.1 to 1.5mm standoff over a self-adhesive magnetic strip scale, providing the count for high-performance positioning.

According to the company, the encoders provide 5µm resolution at 20m/s and 1µm at 4 m/s. Non-contact magnetic sensing delivers dependability in applications that are too dusty, dirty, greasy or destructive for optical encoders, while providing OEMs with major cost economies.

Simple to install, the LM10 has 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 100m in easy-to-handle coils. Engineered for extreme service, the solid-state linear encoders can operate in temperatures from -20 to +85°C, have waterproof sealing to IP68, and high resistance to shock, vibration, and pressure.

The non-contact, frictionless operation eliminates wear while reducing inertia for high precision at high speeds and acc/dec. The 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, and electronic chip/board production.

The encoders come in digital or analog output models and offer customer-selectable resolutions including 1, 5, 10, 50 and 100µm 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 10µm resolution, 20 m/s at 5µm resolution and 4 m/s at 1µm.
