Product: RESOLUTE™

Renishaw RESOLUTE True-Absolute Optical Encoder Series

Renishaw (UK) is a world leader in precision measurement and encoders. RESOLUTE is a high-speed, fine-resolution true-absolute open optical encoder system: the readhead acts as an ultra-fast miniature camera imaging a single-track 30 um-pitch absolute scale, with a DSP computing absolute position - position is available immediately at switch-on with no battery and no multi-track de-phasing. Linear resolution down to 1 nm, rotary up to 32 bit (4,294,967,296 counts/rev, ~0.0003 arcsec), max reading speed 100 m/s (36,000 rpm), SDE +/-40 nm and jitter <10 nm RMS, with dirt-immune scale reading. Variants include UHV (120 C bake-out), ETR (-40 to +80 C) and FS (functional safety SIL 2 / PL d); serial interfaces cover BiSS C / BiSS Safety, FANUC, Mitsubishi, Panasonic, Siemens DRIVE-CLiQ and Yaskawa. Linear scales RTLA/RELA/RSLA up to 21 m; RESA30/REXA30 rotary rings 52-550 mm with typical installed accuracy of +/-1.9 arcsec. Used in semiconductor equipment, radar/SATCOM antennas, precision rotary tables and high-end robot joints.

Ouster OS1 Max Rev8 256-Channel Long-Range High-Resolution Imaging Lidar

Ouster OS1 Max Rev8 256-Channel Long-Range High-Resolution Imaging Lidar

The Ouster OS1 Max is the flagship long-range imaging lidar of the Rev8 OS series and the first to reach 256 vertical channels (also 64/128): 865 nm Class 1 eye-safe laser, 360 deg x 43.9 deg FOV, 512-4096 horizontal columns, 5-40 Hz configurable rotation. In 1024 @ 10 Hz mode it reaches 350 m on 80% Lambertian targets and 200 m on 10% targets (both >90% detection probability at 100 klx sunlight), with 500 m max representable and 0 m minimum range; range accuracy is +/-1.25 cm (Lambertian) / +/-2.5 cm (retroreflective) at 0.1 cm resolution, up to 2 returns and 10,485,760 points per second. Native RGB-D color point cloud (116 dB dynamic range) carries RGB, range, signal, reflectivity, NIR, channel, azimuth and timestamp per point; a synchronous IMU runs at 640/1280/2560 Hz. Data leaves over gigabit Ethernet UDP with PTP/gPTP/NMEA/PPS time sync (<1 ms error) and <10 ms latency. It runs from 12/24 VDC (9-58 V) at 15-25 W (19 W nominal, 28 W peak starting at -40 C), measures 87 mm diameter x 82 mm and weighs 670 g (720 g with halo cap); IP68/IP69K, -40 to +85 C, 100 g shock and 10 Grms vibration. Engineered for functional safety (ASIL-B, SIL-2, PLd) with an on-sensor 3D Zone Monitor and designed for cybersecurity to ISO 21434 / UNECE WP.29 / IEC 62443 / ISO 27001. Built for long-range industrial sensing, off-highway vehicles, autonomous cars, trucks and buses, traffic and security monitoring, and 3D mapping vehicles.
