Application Scenarios:
On a high-speed conveyor system in an automotive parts assembly plant, precise verification of component presence is critical before a robotic arm performs a welding operation. A REOTRON 567LH-DP24 inductive sensor is mounted precisely at the load station. As a metal bracket arrives on a pallet, the sensor detects its presence and sends a 24V DC signal to the PLC, confirming the part is correctly positioned and present. Its shielded design allows for side-by-side mounting with other sensors without interference, and its rugged IP67-rated housing withstands constant vibration and airborne oil mist. This reliable detection prevents the robot from welding empty air or misaligned parts, directly addressing the core pain points of production errors, robot collisions, and unscheduled downtime.
Technical Principles and Innovative Values:
Innovation Point 1: Eddy-Current Based Sensing for Robust Metal Detection. The REOTRON 567LH-DP24 operates on the inductive eddy-current principle. Its oscillator coil generates a high-frequency electromagnetic field at the sensing face. When a conductive metal target enters this field, eddy currents are induced in the target, which dampens the oscillator’s amplitude. This change is detected by the sensor’s circuitry, triggering a solid-state PNP switch. This technology provides exceptional reliability for detecting ferrous and non-ferrous metals, is immune to ambient light, dust, and most contaminants, and offers a long operational life with no moving parts to wear out.
Innovation Point 2: Shielded Design for Dense Installation and Flexible Mounting. This sensor features a shielded (flush-mountable) design. The electromagnetic field is concentrated at the front face, allowing the sensor to be mounted flush in a metal bracket without loss of sensing range. This enables dense installation in control panels or machines where sensors must be placed close together without mutual interference, maximizing design flexibility and space utilization in complex automation systems.
Innovation Point 3: Industrial-Graded Durability and Simplified Integration. Housed in a nickel-plated brass or stainless steel M12 cylindrical body with an IP67 rating, the 567LH-DP24 is built for harsh industrial environments, resisting coolants, oils, and mechanical impacts. The standard 3-wire DC configuration (Brown+/Blue-/Black Signal) and common PNP switching logic make it universally compatible with PLCs, controllers, and relay modules, simplifying wiring, reducing integration time, and ensuring easy replacement across a wide range of equipment.
Application Cases and Industry Value:
A manufacturer of packaging machinery faced frequent false signals and sensor failures on a high-speed cartoning line. The existing sensors were not shielded, causing crosstalk, and their housings were degraded by chemical cleaners. This led to machine jams and over 5 hours of weekly downtime for troubleshooting and replacement. They standardized on the REOTRON 567LH-DP24 for all critical end-of-stroke and presence detection points. The shielded design eliminated cross-talk, and the robust IP67 housing withstood daily washdowns. Within a month, false triggers were eliminated, and sensor-related downtime dropped to near zero. The maintenance supervisor noted, “Switching to the 567LH-DP24 sensors brought instant reliability. Their consistent performance in a wet, electrically noisy environment has made them our go-to standard. We’ve dramatically cut maintenance time and increased line availability.” This demonstrates the sensor’s value in boosting Overall Equipment Effectiveness (OEE) through superior reliability, reduced waste, and lower total cost of ownership.

Installation, Maintenance, and Full-Cycle Support:
Installation of the REOTRON 567LH-DP24 is straightforward. For the threaded body version, simply mount it in an M12 threaded hole, using a wrench on the hex flats and ensuring not to overtighten. For flush mounting, ensure the sensing face is aligned with the metal surface. Correct wiring is crucial: connect the brown wire to 24V DC+, the blue wire to DC common (0V), and the black (signal) wire to the PLC input. The integrated LED provides immediate feedback for commissioning and diagnostics. Always ensure the target metal is within the 4mm nominal sensing distance and accounts for the sensor’s hysteresis to guarantee reliable switching.
Maintenance is minimal due to its solid-state design. The primary tasks are periodic visual inspection for physical damage or buildup of metallic debris on the sensing face, which should be cleaned with a soft cloth. Check cable integrity for cuts or abrasions, especially at the gland entry point. If a sensor fails, first verify power (24V DC) is present and the load (PLC input) is functional. Replacement is a simple process of disconnecting power, unscrewing the old unit, and installing the new one, ensuring the wiring is identical.
