The Leuze IS 230MM/4NO-22E (Part Number: 50109720) is a specialized extended-range non-contact metal detection switch belonging to Leuze electronic's standardized Series 230 (Germany). Built with a heavy-duty M30 cylindrical chromed brass body and offering an extraordinary flush scanning distance of 22 mm, this sensor delivers unmatched mechanical protection, extreme sensing clearance, and long-term durability across heavy industrial machine automation processes.

KEY PRODUCT FEATURES AND OPERATIONAL ADVANTAGES:
1. Exceptional 22 mm Extended Operating Range – Flush / Embedded Installation (-22E):
Delivers a massive nominal sensing range Sn of 22 mm (assured operating range Sa: 0 to 17.8 mm) while maintaining full flush-mount compatibility with metallic surrounding structures. This flush installation protects the active sensing face against direct physical impacts from vibrating or swaying workpieces while saving critical machinery footprint.
2. 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.
3. PNP Normally Open (NO) Transistor Output:
Equipped with a solid-state PNP NO output capable of handling up to 200 mA switching current, ensuring seamless hardware integration with modern PLC control systems (Siemens, Mitsubishi, Omron, Schneider, Delta, etc.).
4. Chromed Brass Shell with PBT Sensing Face:
The precision-machined M30x1.5 mm threaded barrel is crafted from rugged chromed brass paired with a wear- and chemical-resistant Polybutylene (PBT) sensing cap. Rated IP67 for water and dust ingress protection, it operates reliably across -25 °C to +70 °C with an outstanding 460-year MTTF rating.
5. Flexible 2m PVC Cable Connection:
Equipped with a 2,000 mm (2 m) oil-resistant 3-wire PVC cable, ensuring dependable electrical signal transmission and high mechanical flexibility inside machinery drag chains.
6. Comprehensive Protective Electronics & Yellow Status LED:
Equipped with built-in output short-circuit protection, reverse power polarity protection, and inductive transient suppression. A bright yellow status LED at the rear delivers clear visual confirmation of switching output states during alignment and diagnostics.
