440N-Z21SS2HN9 Sensor – Key Features

1. Sensor Type & Technology

• Inductive proximity sensor (detects metal objects without contact).
• Shielded design (flush-mountable for precise metal detection).
• High switching frequency (up to 1 kHz for fast-moving targets).

2. Detection Range & Performance

• 2 mm nominal sensing distance (Sn) for ferrous metals.
• Reduced sensing range for non-ferrous metals (e.g., aluminum, brass).
• Hysteresis: ≤ 10% of Sn (stable switching points).

3. Electrical Specifications

• Output Type: NPN Normally Open (NO) (HN9 suffix typically indicates NPN).
• Voltage Range: 10–30V DC (industrial standard).
• Current Load: ≤ 200 mA (short-circuit and reverse polarity protected).
• Response Time: ≤ 0.5 ms (ultra-fast for high-speed automation).

4. Mechanical & Environmental

• Housing: Stainless steel (SS2) for corrosion resistance.
• Thread Size: M12 x 1 mm (standard industrial threading).
• Protection Rating: IP67/IP69K (dustproof, waterproof, high-pressure washdown).
• Operating Temperature: –25°C to +70°C.

5. Special Features

• LED status indicator (power and output state).
• EMC immunity (resistant to electromagnetic interference).

6. Certifications & Approvals

• CE, cULus, IEC 60947-5-2 (industrial safety standards).

Model Number Decoding (440N-Z21SS2HN9)

• 440N: Series (inductive proximity sensor).
• Z21: Flush-mounted, shielded design.
• SS2: Stainless steel housing.
• HN9: NPN NO output (other variants: HP9 = PNP NO).

Typical Applications

✔ Machine tooling (position sensing of metal parts).
✔ Conveyor systems (detecting metal components).
✔ Food/beverage industry (stainless steel housing for hygiene).
