Ultrasonic sensors - UC4 is part of SICK's industrial ultrasonic sensors portfolio. The UC4 family is designed for professional machine, production and process environments where dependable sensing, safety monitoring, measurement or motion feedback is required. This product entry is written as customer-facing ecommerce content and keeps the technical identity tied to the SICK family documentation rather than introducing unsupported specifications.
The core function of the UC4 family is to provide a defined, repeatable signal to the automation system. The published source describes the product around its operating principle and configuration structure, while the technical table below records the values that can be stated directly from the SICK documentation. Where a parameter is configuration-dependent, that dependency is retained rather than replaced with an assumed single value.
The documented application strengths of this family include “Ultrasonic measurement in compact sensing ranges” “Resolution ≥0.1 mm and repeatability ±0.15%” “Analog 4 ... 20 mA or 0 ... 10 V options” “PNP / NPN / push-pull digital outputs”. These characteristics make the range relevant where repeatable machine signals, controlled sensing, dependable safeguarding, process measurement or motion feedback are required.
The SICK documentation publishes Operating measuring range: 13 ... 150 mm depending on type; Limiting range: 150 mm / 250 mm depending on type; Resolution: ≥0.1 mm; Repeatability: ±0.15%; Response time: 10 ... 24 ms / 24 ms depending on type. These values define the engineering envelope described by the source material and should be read together with the selected ordering code where the family contains multiple configurations.
The SICK documentation publishes Output time: 5 ... 8 ms; Switching frequency: 30 Hz / 100 Hz; Analog output: 4 ... 20 mA (≤500 Ω) or 0 ... 10 V (≥100 kΩ); Communication: IO-Link v1.1; Enclosure rating: IP65 / IP67. These values define the engineering envelope described by the source material and should be read together with the selected ordering code where the family contains multiple configurations.
The published SICK configuration defines the electrical and communication architecture for UC4. Depending on the documented type, this can include the stated supply, switching outputs, analog signals, safety outputs, industrial communications, connectors or other interfaces. The specification table keeps those source values explicit so they can be checked during engineering and purchasing.
The SICK documentation publishes Ambient temperature: −25 °C ... +70 °C. These values define the engineering envelope described by the source material and should be read together with the selected ordering code where the family contains multiple configurations.
The family is intended for industrial installation, with the source documentation defining its housing, enclosure, temperature, mechanical and connection characteristics where these are published. No additional material or environmental ratings have been added where SICK does not publish them for the family row.
For system integration, selection should follow the required sensing or safety range, output behaviour, connection, mounting arrangement and environmental conditions. The SICK documentation is structured around ordering variants, so the exact part number should be checked before purchase or installation. This is particularly important where the family offers multiple electrical interfaces, optical arrangements, resolutions, safety functions or housing options.
Commissioning should use the SICK installation and configuration documentation for the selected ordering code. Confirm mechanical clearances, electrical compatibility, required accessories, safety architecture and application-specific parameters before putting the device into service. For safety-related products, the final system design must follow the applicable SICK documentation and the relevant safety standards for the complete machine.
The published SICK application scope for this family includes Presence detection, Distance measurement, Level and position sensing. The appropriate use depends on the actual machine architecture, target object or medium, required operating range and selected variant. The family is particularly suited to engineering-led procurement where exact product configuration matters.
Use the official SICK ordering configuration to select the exact version required for the installation. The technical table below is the source-backed selection reference for this ecommerce listing; it deliberately avoids filling unsupported values with estimates or generic industry assumptions.
