K&S Wire Bonder Fiber Optic Amplifier 03401-1032-000-02

This component is a fiber optic amplifier used in K&S wire bonding machines (part number: 03401-1032-000-02). In the spare parts market, it is circulated as a "Banner" fiber optic amplifier and is designed for use with a corresponding fiber optic probe. It converts changes in light intensity—detected by the probe—into switching signals, which are then sent to the main controller. These signals are used for tasks such as detecting the presence of wire, verifying proper wire feeding, monitoring mechanical positioning, and triggering alarms for wire breakage. Featuring rapid response times and high resistance to electromagnetic interference, it is well-suited for the confined spaces and high-frequency operational environments typical of wire bonding machines. The amplifier’s threshold, time delay, and NO/NC (normally open/normally closed) settings must be configured to match the original machine’s calibrated values; otherwise, the system may produce false alarms or fail to detect events.
