Technical Datasheet: TURCK BC3-M12-AN6X-H1141

Product Type: Capacitive Proximity Sensor

Ident-No.: 2601012

1. Product Characteristics & Application

• Sensor Type: Capacitive Proximity Sensor (designed to detect both metallic and non-metallic objects, liquids, or bulk materials).

• Housing Design: Threaded cylindrical barrel type (M12 × 1) with a robust chrome-plated brass construction.

• Sensing Range ($S$): 0.3…3 mm (adjustable or fixed high-precision window).

• Mounting: Flush mountable (indicated by the flush mounting layout symbol on the packaging label).

• Special Features: Perfect for non-contact presence detection of non-conductive mediums, level tracking of small plastic granules, or sensing glass and cardboard targets where standard inductive sensors cannot function.

2. Electrical Data

• Operating Voltage: 10…30 V DC

• Rated Current Consumption: ≤ 200 mA

• Electrical Design: DC NPN (Note: Please pay close attention to this designator as it operates on NPN logic, unlike your previous PNP sensors).

• Output Function: Normally Open (NO)

• Protection Class: Class 2 Source compliant (UL listed, 35 GN) / Type 4x indoor, 13

3. Performance & Dynamic Data

• Switching Frequency: Highly responsive cyclic output optimized for precision object validation and tracking loops.

• Short-Circuit Protection (SCP): Yes

• Overload & Reverse Polarity Protection: Yes

4. Mechanical & Environmental Data

• Dimensions: M12 × 1 mm standard industrial metric thread

• Housing Material: High-grade chrome-plated brass / robust metal barrel

• Ambient Operating Temperature: Standard industrial thermal resilience profile

• Country of Origin: Made in Germany

• Item Code / Batch: 3316H

• Included Accessories: Mounting locknuts and tooth lock washers (visible at the bottom of the pouch).

5. Electrical Connection & Wiring Layout

The sensor features an integrated standard male circular connector head (M12 × 1, 3-pin active setup).

Pinout Assignment:

• Pin 1: Brown wire (BN) → + (10…30 V DC Power Supply)

• Pin 3: Blue wire (BU) → – (0 V Ground / Common)

• Pin 4: Black wire (BK) → Output Switching Signal (Load)
