MSTBODEN KA200 Linear Glass Scale DRO. High-Precision 1um Optical Linear Encoder for Mills & Lathes. The KA200 is a compact optical glass linear encoder, smaller than the KA500 series, built for machines where installation space is tight. It delivers 1um resolution with A/B/Z signal output, ideal for retrofitting a Digital Readout (DRO) system onto milling machines and lathes. 1um resolution with 0.02mm pitch grating for accurate positioning feedback. Smaller optimized housing than the KA500 series, suited to space-restricted machine setups. Standard TTL A/B/Z signal output for direct DRO or controller compatibility. Shielded metal housing with a 2M metal hose signal cable for workshop reliability. 120mm – 200mm (per variation). DC 5V ±5%, 80mA. ? Choosing Your Option. This listing offers multiple measuring-range variations from 120mm to 200mm in 10mm increments. Each option includes one complete linear scale unit with signal cable matching the selected measuring range only, select the exact length required for your machine axis. Q: What signal type does this scale output? A: It outputs a standard TTL A/B/Z signal. Q: What power supply does it need? A: DC 5V ±5%, drawing approximately 80mA. Q: Can I use this on a lathe or mill? A: Yes, it is designed for retrofitting DRO systems on milling machines and lathes. Q: Does the measuring range affect the cable?
