The FHDK 04G6111 from Baumer is a precision-engineered subminiature photoelectric sensor that uses background suppression to distinguish targets accurately even when the background is reflective or irregular. It operates using a pulsed point source LED with a 660 nm wavelength and offers a reliable measuring distance of 30 mm ±2 mm. Its extremely fast response time of less than 0.5 ms ensures it performs well in high-speed automation lines without delay or signal lag.
Powered by an 11–30 VDC supply voltage, the sensor consumes only 30 mA, making it energy efficient while maintaining consistent output. It supports a push-pull output circuit with a maximum current of 50 mA and is protected by short-circuit safety with a voltage drop of under 2 VDC. The housing is a robust rectangular ASA plastic body, measuring just 4 mm x 44.8 mm x 6.2 mm, making it ideal for tight machinery or compact sensor arrays. The sensor includes an IP65 protection rating and operates reliably within a temperature range of -10°C to +50°C. Its 3-pin, 2-meter cable connection ensures quick integration into control systems with minimal effort.
The Baumer FHDK 04G6111 Subminiature Photoelectric Sensor is perfect for micro-positioning tasks in robotics, fine edge detection in packaging machines, and precise part presence verification in compact production cells. Its subminiature size is especially useful for mounting inside narrow equipment where standard sensors can’t fit. Maintenance engineers favor this model for its “install and forget” reliability and the lack of complex setup. Students in mechatronics and automation labs also benefit from its clear LED output and stable background suppression when learning about sensing systems in real-time applications. Whether used in production, R&D, or educational setups, this sensor ensures precision, speed, and durability in one of the smallest available formats.
