Epro PR6424/117-121 Eddy Current Displacement Sensor

FAQ

Q1. What is the PR6424/117‑121 used for?
It is a non‑contact eddy current displacement sensor used to measure radial or axial shaft displacement, vibration, eccentricity, and dynamic motion in industrial rotating machinery.

Q2. What measurement ranges does this sensor support?
It supports a static displacement range of ±2.0 mm and a dynamic range of 0–1,000 µm.

Q3. What are the physical dimensions of this sensor?
Sensor head diameter is 16 mm × body length ~40 mm × cable diameter ~2.8 mm × standard cable length 1 m.

Q4. What thread size does this sensor use for mounting?
The sensor mounts using an M18 × 1.5 threaded housing.

Q5. What operating temperature range can it handle?
It is designed to operate reliably from −35 °C to +180 °C.

Q6. What material should the target shaft be?
It is optimized for ferromagnetic steel shafts such as 42CrMo4 and similar materials for accurate detection.

Q7. Does this sensor produce usable output by itself?
No — it typically requires a compatible signal conditioner or converter to produce a usable analog or digital output for monitoring systems.

Q8. How heavy is the PR6424/117‑121 including its cable?
With a standard 1 m cable, the sensor weighs about 0.20 kg.
