RESR and SiGNUM™ Optical Angle Encoders from Renishaw. Renishaw's high accuracy angle encoders are available in a large range of diameters and line counts to provide compatibility with standard controllers. Based on a one-piece stainless steel ring with axial graduations marked directly onto the periphery. Available in both standard or low inertia sections to suit a diverse ... (read more)

Rotary encoders serve as measuring sensors for rotary motion, and for linear motion when used in conjunction with mechanical measuring standards such as leadscrews. (read more)

New line of absolute optical encoders world's first with 27-bit resolution at 36,000 rpm, 1 nanometer at 100 m/s.

Fine-pitch system delivers true absolute positioning in linear or rotary models. Unique single-track scale eliminates de-phasing from misalignment, allows wider setup tolerances.

Renishaw's new RESOLUTE™ optical encoder system is the world's first true absolute encoder cap... (read more)

The iC-ML supplies the absolute linear position of a magnetic tape placed above the chip's package, with a Hall sensor array granting a reasonable system assembly tolerance. Controlled signal amplitudes are ensured by the embedded signal conditioning circuit also monitoring a "loss of magnetic field" condition. (read more)

The iC-MH 12-bit angular encoder is a position sensor with integrated Hall sensors for scanning a permanent magnet. The signal conditioning unit generates constant-amplitude since cosine voltages that can be used for angle calculation. The resolution can be programmed up to a maximum of 4,096 angular increments per rotation. (read more)

Renishaw's new SiGNUM™ encoder range offers high accuracy, resolution, repeatability with high speed, high operating temperature, ultra-low cyclic error and IN-TRAC™ optical reference mark, which remains phased over the entire speed and temperature specification. (read more)

iC-MA supplies the absolute angular position of a magnet placed above or below the chip's package, with a set of four distributed Hall sensors granting a reasonable system assembly tolerance. Controlled signal amplitudes are ensured by the embedded signal conditioning circuit also monitoring a "loss of magnet" condition for z-axis detection. (read more)

Ready for anything — shock, vibration, pressures, temperature extremes, high speeds and acc/dec, even immersion — tough-guy RLS magnetic rotary encoders take on problem conditions with "fit and forget" reliability, go-anywhere versatility, and high performance at low cost. (read more)

OnAxis magnetic encoders bring high performance, solid-state construction, simple in-line mounting and low price to motor control, shaft position and velocity measurement applications for OEM manufacturers. Non-contact operation provides zero-wear "fit and forget" reliability. Units deliver IP68 sealing, temps from -40°C to 125°C, strong resistance to shock, vibration, G forces, pressures. (read more)
