The Leuze IS 230MM/4NO-10E-S12 (Part Number: 50109713) is a heavy-duty non-contact inductive proximity switch belonging to Leuze electronic's standardized Series 230 (Germany). Featuring a large-format M30 cylindrical nickel-plated brass casing, this sensor delivers exceptional mechanical robustness, impact resistance, and high-precision target verification for industrial automated machinery.

KEY PRODUCT FEATURES AND OPERATIONAL ADVANTAGES:
1. High-Frequency Inductive Eddy Current Principle – Zero Mechanical Wear:
Detects metallic targets through electromagnetic field damping when conductive metals (ferrous or non-ferrous) enter the active sensing zone. Its 100% non-contact operation prevents mechanical wear and remains completely impervious to cutting fluids, lubricants, dust, or metal shavings.
2. Flush / Embedded Installation Design (-10E):
Provides a nominal sensing range Sn of 10 mm (assured operating range Sa: 0 to 8.1 mm). The flush-mountable construction allows the sensor to be embedded flush into machine tool frames and metallic fixtures, saving critical mounting space and shielding the sensing face against physical collision damage.
3. High Switching Frequency 1,200 Hz (1.2 kHz) & Fast Response:
With a rapid switching rate of 1.2 kHz, it is ideally suited for flywheel gear tooth counting, camshaft rotation monitoring, conveyor indexing, and high-frequency tachometer applications.
4. Exceptional Long-Term Reliability with 930-Year MTTF:
Manufactured under stringent European quality standards, offering high positional repeatability (< 5%) and minimal temperature drift (< 10%). Its outstanding Mean Time To Failure (MTTF) of 930 years ensures dependable 24/7 continuous industrial operation.
5. Rugged Nickel-Plated Brass Housing with M12 Connector (-S12):
The M30x1.5 mm threaded body is crafted from heavy-duty nickel-plated brass paired with a durable, chemical-resistant Polybutylene (PBT) sensing cap. The standard 4-pin M12 male connector allows rapid, error-free plug-and-play wiring and servicing.
6. Comprehensive Internal Protection & High-Visibility Status LED:
Equipped with built-in output short-circuit protection, reverse supply polarity protection, and inductive transient kickback suppression. A bright yellow status LED at the rear delivers clear visual confirmation of switching output states during alignment and diagnostics.
