The WMK-105x/10x miniature scanning head with remotely located signal conditioning electronics are best suited for limited space applications. The signal conditioning electronics are located within an oversized connector that can also be IP-67 rated. They deliver either RS422 TTL square waves (to 0.125um arc length resolution) or industry standard 1VPP sine/cosine (20um arc length period). These read heads are IP-67 rated and are insensitive to environmental pollution like grease, oil, coolant, dust and dirt.
