Technical Datasheet: TURCK Ni8U-MT12-AP6X-H1141

Series: uprox+ (Extended Range Factor 1 Sensor)

Ident-No.: 1644240

1. Product Characteristics & Application

• Sensor Type: Inductive Proximity Sensor

• Housing Design: Threaded barrel type (M12 × 1)

• Sensing Range (Sn): 8 mm (Extended sensing range for M12 size)

• Mounting: Non-flush mountable (indicated by the smooth unthreaded front tip visible on the physical sensor).

• Special Features: upros+ technology (Factor 1) — detects all magnetic and non-magnetic metals (steel, stainless steel, brass, aluminum, copper) at the exact same extended distance of 8 mm without any reduction factor. It offers high immunity to strong magnetic fields (e.g., weld field immune) and features a robust PTFE-coated brass or chrome-plated brass housing.

2. Electrical Data

• Operating Voltage: 10…30 V DC

• Rated Current Consumption: ≤ 200 mA

• Electrical Design: DC PNP

• Output Function: Normally Open (NO)

• Protection Class: Class II Connection required (UL / CSA listed)

3. Performance & Dynamic Data

• Switching Frequency: High response speed optimized for high-velocity target detection and counting.

• Short-Circuit Protection (SCP): Yes

• Overload & Reverse Polarity Protection: Yes

• Status Indication: Integrated 360-degree visible yellow LED ring at the connector end (visible through the protective cap on the sensor body).

4. Mechanical & Environmental Data

• Dimensions: M12 × 1 mm thread / Total barrel length approx. 52 mm

• Housing Material: Metal, Marine-grade Brass (PTFE or Chrome-plated)

• Ambient Operating Temperature: -30 °C…85 °C

• Ingress Protection (IP Rating): IP 68 / IP 69K

• Country of Origin: Made in Germany

• Item Code / Batch: 1946B

5. Electrical Connection & Wiring Layout

The sensor features an integrated standard male thread connector head (M12 × 1, 3-pin configuration).

Pinout Assignment:

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

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

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