Miniature linear encoders
SR-P40, SR-P200, and SR-P1000 ultra-small encoders use light reflection-diffraction technology to make alignment and adjustment easier than permeable types.
Features & benefits
Resolution of 2 µm with maximum speed of 4 m/sec (P40); 1 to 4 µm with maximum speed of 4 m/sec (P200); and 0.32 to 0.08 µm with maximum speed of 1.5 m/sec (P1000)
Quartz glass with length of 15 to 1,000 mm or film linear scales with length of 15 to 200 mm
Grating pitch of 80 µm

Easily-mountable linear encoders
LIDA 200 encoders control low-end linear operations in an exposed package.
Features & benefits
Same graduations, accuracy, and reliability of 400 series
Grating period of 200 µm for analog systems (for digital systems, signal periods of 5, 1, and 0.5 µm) available
Higher speeds (10 m/sec) than LIDA 400; offers higher contamination resistance
Mount by scale tape that comes in rolls with reference marks

Position transducer
Series M general-capability position transducer gives long displacement range, multiple mounting options, and size efficiency.
Features & benefits
Maximum range of 85 in.
Choice of analog (voltage divider or rheostat) or digital (quadrature) sensors
Reduced displacement cable fleet angle increases repeatability and reduces cable overlap
RoundAbout cable exit for 360° × 360° orientation eliminates need for transducer relocation or pulleys in a 3D environment

Industrial Ethernet sensor
R-series EtherCat sensor provides high-speed position feedback and data transfer for industrial Ethernet.
Features & benefits
Resolution to 1 µm, speeds to 0.2 mm/sec, and update time of 1 µsec (independent of stroke)
Synchronizes clock signals for high-speed deterministic control
Use with one to five position magnets; customize to document position, velocity, acceleration, and smart functionality
LEDs indicate normal operation, programming mode, magnet not detected, missing external interface signals, and insufficient or out-of-range input power
