What Is the TURCK NI50U-CK40-VP4X2-H1141?
An inductive proximity sensor detects metal objects without requiring physical contact. These sensors are widely used in industrial automation to detect the presence, position, movement, or end position of machine components.
The TURCK NI50U-CK40-VP4X2-H1141 is designed for this type of industrial detection application.
Its 50 mm rated switching distance makes it suitable for applications where a longer sensing range is required compared with many conventional inductive proximity sensors. TURCK lists the model as an inductive sensor with extended switching distance.
The sensor's rectangular CK40 design measures approximately 65 × 40 × 40 mm, while the active face can be oriented in five directions.
Key Features of TURCK NI50U-CK40-VP4X2-H1141
1. 50 mm Rated Switching Distance
One of the most important characteristics of the NI50U-CK40-VP4X2-H1141 is its 50 mm rated switching distance.
This extended sensing distance can be useful when machine components need to be detected without placing the sensor very close to the target.
The secured operating distance is specified as up to approximately 0.81 × the rated switching distance, according to TURCK's technical documentation.
2. uprox+ Technology
The NI50U-CK40-VP4X2-H1141 belongs to TURCK's uprox+ family.
TURCK describes uprox+ sensors as using a multi-coil system and highlights their switching-distance performance, flexibility, and operational reliability. The sensor also provides Factor 1 for all metals, which is an important characteristic when detecting different metal targets.
3. Factor 1 for All Metals
The sensor is specified with Factor 1 for all metals.
This feature can simplify sensor selection in applications where the detected targets may include different types of metal.
Instead of relying on a different correction factor for different metal targets, the Factor 1 characteristic provides a more consistent basis for evaluating the sensing distance.
4. PNP Complementary Output
The NI50U-CK40-VP4X2-H1141 uses a 4-wire PNP complementary-contact output.
The electrical specification lists an operating voltage range of 10–65 VDC and a rated DC operating current of up to 200 mA. The sensor also provides short-circuit and reverse-polarity/wire-break protection according to the technical documentation.
This makes it suitable for integration into many industrial DC control architectures, provided the connected PLC or controller is compatible with the sensor output.
5. M12 × 1 Connector
The sensor uses an M12 × 1 male connector.
M12 connectors are widely used in industrial automation because they provide a standardized and practical connection method for sensors and other field devices. TURCK lists the electrical connection as an M12 × 1 connector.
6. IP68 Protection
The TURCK NI50U-CK40-VP4X2-H1141 has an IP68 protection rating.
This is particularly relevant for industrial environments where sensors can be exposed to dust, moisture, or other challenging conditions. The suitability of the sensor for a specific installation should still be evaluated against the actual environmental conditions.
7. Resistant to Magnetic Fields
TURCK lists the NI50U-CK40-VP4X2-H1141 as resistant to magnetic fields, with the technical documentation specifying DC and AC field stability values.
This can be an important consideration in machinery and automation environments where magnetic fields may affect conventional sensing technologies.
TURCK NI50U-CK40-VP4X2-H1141 Applications
The sensor can be used in many industrial automation applications where non-contact detection of metal objects is required.
Machine Position Detection
The sensor can detect the position of moving metal components on automated machinery.
End-of-Travel Detection
Inductive sensors are commonly used to identify whether a mechanical component has reached a defined position.
Conveyor Systems
The TURCK NI50U sensor can be used to detect metal parts moving through automated material-handling equipment.
Production Machinery
Manufacturing machines can use inductive sensors for part presence detection, machine-position feedback, and sequencing functions.
Packaging Equipment
Sensors can help detect metal components and machine mechanisms during automated packaging operations.
Industrial Automation
The combination of long sensing distance, PNP output, M12 connection, and IP68 protection makes the sensor suitable for a variety of industrial automation installations.
Why the 50 mm Switching Distance Matters
When selecting an inductive proximity sensor, the sensing distance is one of the first specifications to check.
The NI50U-CK40-VP4X2-H1141 provides a rated switching distance of 50 mm, which is clearly identified in TURCK's product documentation.
A longer sensing distance can provide additional mechanical installation flexibility because the sensor does not necessarily need to be positioned immediately next to the target.
However, the actual operating distance depends on the target, mounting arrangement, environmental conditions, and sensor specifications. Engineers should use the manufacturer's technical data rather than assuming the rated switching distance will be identical in every application.
Installation and Selection Considerations
Before installing or replacing a TURCK NI50U-CK40-VP4X2-H1141, check the following:
Confirm the complete model number.
Verify the required sensing distance.
Check the target material.
Confirm the 10–65 VDC supply requirement.
Verify PNP output compatibility.
Check the M12 × 1 connector.
Confirm available installation space.
Check whether flush or non-flush mounting is required.
Verify environmental temperature.
Confirm the required IP protection level.
TURCK specifies the standard model as suitable for non-flush mounting and lists an ambient temperature range of -30 to +85 °C.
TURCK NI50U-CK40-VP4X2-H1141 Replacement Guide
If an installed NI50U-CK40-VP4X2-H1141 needs to be replaced, matching only the general description "TURCK inductive sensor" is not sufficient.

NI50U-CK40-VP4X2-H1141 vs. Similar TURCK Sensors
TURCK offers many inductive proximity sensors with similar-looking housings and product names.
For example, the NI50U-CK40-VP4X2-H1141/3GD is a related model but adds ATEX approvals for specific hazardous-area applications. It has a different TURCK order ID and should not be treated as automatically interchangeable with the standard NI50U-CK40-VP4X2-H1141.
This is why industrial buyers should always compare the complete product reference before ordering.
