Leeb test probe M502.271 — Type D, 11 mJ impact energy

Leeb test probe M502.271 for portable rebound hardness testing; compact impact sensor with a hardened 3 mm ball tip for measurements on sufficiently thick and heavy specimens

• 11 mJ impact energy for repeatable readings
• 3 mm hardened ball contact tip
• Compact 147 x 20 mm robust design
• Suitable for specimens ≥5 mm thick and ≥5 kg

Precise impact sensing for repeatable hardness readings

The compact impact sensor provides a defined impact energy of 11 mJ, which stabilises the rebound behaviour and supports consistent measurement results across multiple hits. The probe’s 3 mm ball contact tip concentrates the impact on a small, hardened surface to deliver comparable rebounds on metallic coatings and bulk materials, reducing scatter in test series. This stability is particularly useful when process control relies on fast checks rather than time‑consuming laboratory methods, so production decisions can be based on reproducible data.

Built for routine inspection and workshop use

With overall dimensions of 147 x 20 mm and a mass of 1 kg, the sensor is deliberately compact and robust for portable applications. The small footprint and durable construction make the unit easy to position on fixtures or inside confined spaces while withstanding everyday handling. The design supports efficient in‑process checks on medium components where a minimum specimen thickness of 5 mm, a minimum mass of 5 kg and a hard coating thicker than 0.8 mm are met, ensuring the impact is transmitted reliably into the sample.

Simple interpretation and integration into workflows

The Type D configuration is a standard format for rebound hardness probes, allowing straightforward pairing with compatible Leeb hardness testers and inspection routines. The hardened ball tip reduces wear and keeps maintenance predictable, while the defined impact energy simplifies correlation with hardness reference blocks. This means teams can establish quick acceptance criteria and maintain traceable control charts without resorting to complex calibration setups for every test cycle.

Practical advantages that save time on the shop floor

Because the probe focuses the impact through a 3 mm ball, localised readings are achievable on small contact areas and coated surfaces where larger indenters would be impractical. The compact design shortens setup times and reduces the need for extensive fixturing, speeding up inspection rounds. For users managing a high throughput of parts, the combination of repeatable rebounds and rugged handling reduces measurement variance and contributes to fewer follow‑up checks.

FAQ

What is the intended use for this probe? The M502.271 Leeb test probe is intended for rebound hardness testing on specimens that meet the minimum thickness and mass requirements; it is used to obtain quick hardness indications for inspection and process control.

Which specimen conditions are required for reliable results? Reliable readings with the probe require a specimen thickness of at least 5 mm, a mass of at least 5 kg and, when present, a hard coating thicker than 0.8 mm to ensure the impact is correctly transmitted.

How does the 3 mm ball tip affect measurements? The 3 mm hardened ball tip concentrates the impact on a small contact area, improving repeatability on coated or locally restricted test surfaces and reducing wear compared with larger contact geometries.

Is the M502.271 suitable for thin or lightweight parts? The probe is designed for medium and larger components; it is not suitable for specimens below the specified thickness or mass limits, as inadequate specimen mass can lead to inaccurate rebound values.

What does the 11 mJ impact energy mean in practice? An impact energy of 11 mJ defines the force delivered during the rebound test and supports consistent rebound behaviour, aiding comparability between measurements and simplifying correlation with hardness references.
