Supply reading head head

Grating by Moore stripes principle, through the photoelectric conversion to digitally represent a linear displacement precision displacement sensor. GBC series grating by reading head, the main scale and interface components. Glass grating light evenly and small translucent engraved lines, gate lines 50 line pairs / mm, its grating pitch of 0.02mm, using four segments obtained after resolution of 5μm count pulses. Bu Generally, the number of lines according to the measurement accuracy of engraving, to determine the moving direction, the lines are carved on the phase difference of 90 ° in two. When the reading head movement, the interface circuit of the photoelectric receiver is the A-phase and B-phase two channel phase difference of 90 ° pulse the output signal is then processed through the digital display system breakdown, the resolution is the grating period divided by the signal segments number, through the electronic signal processing resolution for subdivision or 1um 5um grating's field of application: processing equipment: lathes, milling, boring, grinding, drilling, EDM machines, wire cutting and other measuring instruments used: Projector , video measuring instrument, tools, microscopes etc. can also be right on the CNC machine tool motion errors from the compensation connected with the PLC, for various types of automated mechanism displacement measurement. grating: Double rubber, five bearing structure, all products are mainly devices for the import, stable performance. Measuring length 100MM-3000MM, Resolution 5U-1U, product high repetition accuracy. The product is compared with similar products, high cost. Measuring range 50mm-3000mm measurement accuracy ± 6um / m ~ ± 10 / m measuring standard: grating period 20um optical glass scale optical measurement systems: transmissive infrared light measurement systems, infrared wavelengths 880nm reaction speed: 60m/min (0.005mm ), 25m/min (0.001mm) reading head sliding system: vertical five bearing Output Signal: TTL/EIA-422-A, signals convey cycle: 20um, supply voltage: DC5 ± 5% with the highest quality materials to produce PU oil resistance, high elasticity and anti-aging rubber seal. Designed by the engineer closed out the best angle and best of hardness, to ensure optimum sealing performance and minimal friction. Readhead sliding part of the structure has been verified using the most reliable and durable five bearing design to ensure that the optical sensor system can grow
