Its fast response and robust design make it a solid choice for equipment that must operate continuously without frequent maintenance.
Designed for demanding environments, the IQ40-20BNOKK0S maintains stable sensing thanks to controlled hysteresis, high repeatability, and resistance to mechanical shock. It operates reliably across a wide temperature spectrum, ensuring dependable performance in both indoor and outdoor industrial facilities. The integrated LED indicators assist technicians by clearly signaling sensor states, making installation and troubleshooting faster. Its reinforced PA66 housing resists chemical exposure and impact, while the flush-mount design simplifies integration into machinery. With reliable detection on a variety of metals and a rapid switching frequency, it supports smooth operation in high-speed automation processes.
The IQ40-20BNOKK0S is the sensor you choose when you need unwavering metal detection in places where ordinary sensors fail. It blends long sensing range, rugged housing, and precise switching into a compact unit that thrives in vibration, moisture, and temperature shifts—delivering reliable performance that keeps production running smoothly.
This model eliminates unstable detection caused by tough environments, variable materials, or inconsistent mounting conditions. It ensures machines detect metal parts accurately—even in harsh washdown zones or high-speed systems—reducing false triggers, preventing downtime, and supporting seamless automation where reliability truly matters.

In automated conveyor systems, metal containers or carriers often shift slightly due to vibration or rapid movement, making consistent detection difficult. The IQ40-20BNOKK0S provides a stable 20 mm sensing capability that tolerates minor misalignment, ensuring each target is identified correctly. Its durable construction handles constant mechanical stress, while fast response times allow the sensor to keep up with high-speed flow. This combination reduces misreads and keeps sorting or stopping mechanisms synchronized with actual part positions, helping production lines stay efficient even during continuous operation.
Food production lines require equipment that can withstand frequent cleaning, moisture, and chemical exposure. The IQ40-20BNOKK0S excels in these environments thanks to its tightly sealed housing and durable materials. It reliably detects metal machine components or carriers used in filling, sealing, or packaging stages where hygiene rules demand regular washdowns. Its sensing stability remains consistent despite temperature changes after cleaning cycles. Clear visual indicators help technicians verify sensor function before restarting equipment, reducing downtime while maintaining compliance with cleanliness standards.
Stamping and forming machines depend on accurate detection to confirm the placement of each metal sheet. Oil mist, vibration, and heavy shock loads can interfere with standard sensors, but the IQ40-20BNOKK0S is engineered to handle these challenges. Its rigid housing resists lubricant exposure, while controlled hysteresis keeps switching signals stable despite mechanical vibrations. Flush mounting protects the sensing surface inside the tooling frame, reducing accidental impact. The sensor’s fast output response supports precise timing, preventing misfeeds and reducing the risk of damaging the press or the die set.
Outdoor access systems often operate in dusty, wet, or temperature-extreme environments. The IQ40-20BNOKK0S maintains reliable performance across wide thermal ranges and resists environmental stress. When installed on automated gates or vehicle control points, it can detect metal plates or brackets attached to passing equipment, enabling accurate position feedback. Its vibration resistance is especially useful in uneven ground conditions where vehicles create mechanical shock. The secure cable entry helps prevent moisture intrusion, making it suitable for long-term use in logistics yards, security checkpoints, or industrial outdoor facilities.
