Turck Bi15U-CP40-FDZ30X2 Capacitive proximity sensors

Product Detailed Description:

The Turck Bi15U-CP40-FDZ30X2 is a capacitive proximity sensor from Turck’s BiS series. Capacitive sensors are designed to detect both metallic and non-metallic objects, including liquids, powders, and granular materials, without making physical contact. They work by sensing the change in the electrostatic field caused by the presence of a target.

This specific model, the Bi15U-CP40-FDZ30X2, features:

• Bi15U: Indicates it’s part of the BiS series, known for robustness and versatility.

• CP40: Specifies it’s a capacitive sensor with a nominal switching distance (sensing range) of 4 mm for a defined reference target (typically a metal plate). This is the standard sensing range for this type.

• FDZ30X2: This part of the code denotes the output type and wiring. “FDZ” typically indicates a PNP, normally open (NO) output with a switching frequency of up to 30 Hz. “X2” usually refers to a 2-wire connection, often NPN type, which can be more convenient for certain installations as it doesn’t require a separate power supply line for the sensor itself (though it needs a common ground).

Essentially, this sensor detects the presence or absence of targets (liquid, plastic, glass, wood, etc.) within its 4 mm sensing range and provides a switching signal via its 2-wire NPN output.

Product Parameters:

(Note: These are typical parameters. Always refer to the specific datasheet for exact values.)

• Type: Capacitive Proximity Sensor

• Connection: Cable or M8 / M12 connector version (confirm variant)

• Temperature Range: -25 °C to +70 °C (operating), -25 °C to +85 °C (storage)

• Weight: Typically around 40-50 g

Product Advantages:

• Versatile Detection: Can detect a wide range of materials, including liquids, powders, and non-metallic solids, not just metals.

• Non-Contact Operation: No physical wear, leading to a long service life and reliable operation.

• High Robustness: Often housed in durable plastic with high IP ratings (like IP 67/IP 69K), making them suitable for harsh industrial environments, including washdown areas.

• Compact Size: The Bi15U series is relatively small, allowing for easy integration into tight spaces.

• Reliable Switching: Provides a clear digital on/off signal.

• Easy Installation: Standard mounting options and available with cables or connectors simplify installation.

Precautions / Notes:

• Environmental Factors: While robust, avoid direct submersion unless specifically rated for it (IP 68). High humidity or conductive contamination on the sensing face can potentially affect performance.

• Sensing Face: Keep the front sensing face clean. Dirt, oil, or condensation can reduce the sensing range or cause false triggering. Regular cleaning may be necessary in dirty environments.

• Installation: Mount the sensor so the sensing face is parallel to the expected target path. Avoid mounting near strong electromagnetic interference sources that could affect the capacitive field.

• Sensing Range: The actual sensing distance can vary depending on the material, shape, and size of the target. The 4 mm nominal range is specified for a defined reference target; real-world targets may be detected at slightly different distances.

• 2-Wire Connection: Ensure the power supply voltage matches the sensor’s requirements. For NPN 2-wire sensors, the load is connected between the output terminal and the positive supply voltage.

• Electrical Safety: Disconnect power before installation, maintenance, or removal.

Product Applications:

The Turck Bi15U-CP40-FDZ30X2 is widely used in various industrial automation applications where detection of non-metallic materials is required:

• Filling and Level Control: Detecting the level of liquids or granular materials in tanks, containers, or silos.

• Packaging Machinery: Detecting the presence of plastic films, cardboard, glass bottles, or other packaging materials.

• Food and Beverage Industry: Detecting bottles, cans, packages, or liquid levels, especially in hygienic areas requiring IP 69K protection.

• Material Handling: Detecting the presence of materials on conveyor belts (e.g., plastic parts, wood, cardboard).

• Plastics Industry: Detecting plastic granules, finished parts, or containers.

• General Industrial Automation: Any application requiring non-contact detection of a diverse range of materials where an inductive sensor would not be suitable.
