BK Mikro TK2-42.03 Broken Tool Detection Detector

TK2-42.03 is BK Mikro’s TK2-series scanner switch configured as a BK2 broken tool detection detector for CNC tooling. Marketed as a scanner switch, the TK2-42.03 appears in distributor listings under BK Mikro's broken tool detection line, signaling its role in tool presence checks and fault signaling within BK Mikro's tool-monitoring ecosystem. Several distributors describe this exact model as discontinued by the manufacturer, with refurbished units occasionally offered by third-party sellers, indicating limited new-production availability. In practice, this device would be used inside a BK Mikro broken tool detection system to verify tool presence or detect tool breakage and communicate a KO/diagnostic signal to the machine controller, triggering a safe stop to prevent damage or defective parts. The BK Mikro family emphasizes safety in automated production through sensor-based monitoring and configurable interfaces for CNC/PLC integration, as highlighted in BK Mikro's product literature and related tool-monitoring resources.
