BL57 Wysokorozdzielczy enkoder liniowy - Inkrementalny optyczny enkoder liniowy z zasadą interferometryczną
The BL57 is a high-resolution, exposed linear encoder with interferometric operating principle in transmitted light design.
The BL57 has a graduation period of 1.6µm and generates a sinusoidal signal period of 400nm due to the laserscale operating principle. This allows resolutions of up to 6.1pm. to be achieved. Due to the high response speed of up to 3m/s, it is perfectly suited for high-precision and fast X/Y stages.
Measuring lengths:30mm - 1060mm
Accuarcy:+/-0,5µm to +/-1,5µm depends on measuring length
Max. resolution:6,1pm
Grating pitch:1,6µm
Signal pitch:400nm
Output signal:1Vpp, TTL, BISS-C, USB, 40bit binary
Reference mark:1
