Baumer ILFK 12P1101/I03 Proximity Sensor

The Baumer ILFK 12P1101/I03 is a non-flush rectangular proximity sensor designed to ensure stable detection in applications where mounting near metal surfaces would disrupt signal integrity. This 30 mm x 38 mm PA 6 plastic body is lightweight yet rugged, engineered to handle challenging industrial conditions without compromising sensitivity. With a 4 mm sensing distance and adjustable hysteresis between 1–20% of the reference range, this sensor allows consistent detection even in dynamic setups or slightly shifting object positions.

The sensor operates on a standard 10–30 VDC supply and outputs a PNP make function (normally open), enabling direct integration into control logic systems. It supports a high-speed 2 kHz switching frequency, making it suitable for fast-moving automation lines. Built-in short-circuit and reverse polarity protection safeguards both the sensor and the connected control system. With an extended 2-meter cable connection for installation flexibility, and an IP67 protection rating, this unit resists water, dust, and factory-floor contaminants. The operating temperature range of 0 to +60°C ensures performance in varied climates. Backed by Baumer’s global reliability, the ILFK 12P1101/I03 is ideal for OEM designs and industrial upgrades requiring compact, fast-response, and non-flush detection.

The Baumer Non-flush Proximity Sensor ILFK 12P1101/I03 is well-suited for automation tasks where the sensor must detect targets beyond recessed or shielded zones. Its non-flush mounting type allows installation on machine frames or brackets without interference from surrounding metal. Common applications include position feedback in pneumatic cylinders, conveyor edge sensing, or material alignment in assembly lines. The 4 mm sensing range offers ample margin to detect targets without needing tight proximity, which is helpful in setups with vibration or slight misalignments.

Maintenance engineers appreciate the simplicity of the 2-meter cable, which makes routing easy during retrofitting or machine servicing. The sensor’s PNP NO output can be directly connected to PLC input cards, reducing wiring complexity. With its fast 2 kHz switching speed, it responds instantly to moving objects like bottles, cartons, or robotic arms. Engineering students can understand and test it in lab automation projects, while senior plant engineers can depend on it for long-term reliability in packaging, food processing, or plastic molding applications. Its rugged PA 6 housing and IP67 protection provide the durability needed for real-world shop floor conditions. In summary, this sensor balances performance, protection, and ease of integration—making it a smart choice for professionals at any level.
