Technical Datasheet: ifm electronic KI0209

Product Code: KI0209

Model / Type Designation: KI-2150-BBOA/NI

Product Category: Capacitive Proximity Sensor / Level Switch

1. Product Characteristics & Application

• Sensor Type: Capacitive Proximity Sensor

• Housing Design: Threaded orange cylindrical plastic barrel type (M30 × 1.5).

• Sensing Range ($S$): 15 mm

• Mounting: Non-flush mountable (indicated by the nf designator next to the range on the label).

• Application: Engineered for non-contact detection of metallic and non-metallic objects, bulk material level tracking (granules, powders, pellets), or liquid level presence directly through non-metallic tank/pipe walls. Highly versatile option across plastic processing, packaging lines, and chemical feeding systems.

2. Electrical Data

• Operating Voltage ($U_B$): 20…250 V AC / DC (Universal wide-range power staging)

• Frequency Range: 45…65 Hz (for AC grids)

• Electrical Design: AC/DC 2-Wire (Note: This sensor runs inline via a 2-wire configuration layout).

• Output Function: Normally Closed (NC) (Indicated by the logic diagram breakdown on the manufacturer package).

• Approvals: CE, EAC, CCC, UKCA

3. Performance & Output Currents

• Rated Operational Current ($I_e$): * Max 200 mA continuous configuration.

  • Peak short-duration rating up to 350 mA (under ambient conditions below 50 °C AC operation).

• Protection Safeguards: High transient voltage surge immunity and basic overload resilience.

4. Mechanical & Environmental Data

• Dimensions: M30 × 1.5 mm metric thread / Classic cylindrical setup length

• Housing Material: High-grade, chemically resilient engineering polymer (PBT / plastic shell)

• Ambient Operating Temperature: Optimized for standard industrial thermal profiles (-25 °C…70 °C)

• Country of Origin: Made in Germany (by ifm electronic gmbh)

• Connection Profile: High-durability 2-core integrated industrial cable setup with bare pre-stripped wire terminals (Brown and Blue leads visible at the base loop).

5. Electrical Connection & Wiring Layout

Because this is a Universal AC/DC 2-Wire sensor, it must always be connected in series with the electrical load. Never connect it directly across the power supply lines without a load, as this will immediately damage the internal switching circuitry.

Core Color Key Assignments:

• Brown Lead (BN): Inline Phase / Positive Supply line path

• Blue Lead (BU): Inline Neutral / Negative Supply line path via the Load element
