Quick Detail

Description

The 21504-04-36-10-02 Proximity Sensor Probe is a high-precision analog voltage transducer engineered for industrial automation and condition monitoring applications. Featuring a 0–20 mm sensing range and a rapid response time of ≤0.5 ms, this probe delivers highly accurate measurements of position, displacement, and vibration in dynamic machinery environments. Its robust 18 mm stainless steel housing ensures mechanical durability and corrosion resistance, while the IP68-rated protection provides full sealing against dust, water immersion, and other harsh environmental factors. The sensor operates over a wide temperature range from –40°C to +105°C and supports supply voltages between 12–30 V DC, maintaining stable analog output under demanding conditions. Equipped with a 3-meter shielded cable, the probe enables secure signal transmission and reduces electrical noise. The threaded flush-mount design allows versatile installation into tight spaces, while its 10 kHz frequency response ensures high-fidelity monitoring of fast-moving machinery components, making it ideal for vibration analysis, position control, and predictive maintenance in automated industrial systems.
