The Baumer IFRM 04P15B1/KS35PL is a high-performance 4 mm Flylead Connector Proximity Sensor designed to meet the rigorous demands of modern factory automation. It features a nominal sensing distance of 0.8 mm and flush mounting capability for accurate close-range detection. Operating on a standard 6 to 30 VDC supply, the sensor uses a PNP make function (Normally Open) output and supports up to 100 mA of output current. Its 3 kHz switching frequency allows rapid object sensing, especially beneficial in applications with moving components or high-speed indexing. The rear-side red LED indicator provides visual feedback, aiding diagnostics and setup.
Structurally, the sensor is housed in a corrosion-resistant stainless steel cylindrical body with a smooth POM sensing face. With a compact 22 mm housing length and 4 mm diameter, itβs built for integration into small and dense assemblies. A robust M8 flylead connector ensures secure and quick installation, especially useful in modular machine setups. Advanced protection features like short-circuit protection and reverse polarity protection extend the sensorβs life in challenging environments. Rated IP67, this proximity sensor offers complete protection against dust ingress and temporary water immersion, while maintaining stable operation between -25Β°C and +75Β°C. These features make it a trusted choice for engineers seeking reliable detection in space-constrained, high-throughput applications.
The Baumer Flylead Connector Proximity Sensor IFRM 04P15B1/KS35PL is ideal for applications where speed, compact design, and durability are essential. Common industrial uses include end-position sensing in pneumatic cylinders, tool position verification in CNC systems, and small-part detection in pick-and-place automation lines. Its quick switching and flush-mount configuration make it highly effective for detecting metal objects with minimal installation space. Indian maintenance engineers value its reliable signal output during rapid cycles and its easy replacement design using standard M8 flylead connectors. For automation design engineers and system integrators, this sensor offers the flexibility to fit into small panels or embedded mechanisms without sacrificing performance. Itβs also a great reference for engineering students studying proximity sensing principles, as it combines electrical protection, build quality, and real-world usability in one compact device.
