What type of sensor is this?

This is a SICK UC12 series ultrasonic distance sensor designed for non-contact detection and distance measurement of natural objects. It uses ultrasonic sensing rather than optical detection, making it suitable for many applications where object colour, surface finish or transparency may affect other sensor types.

What is the sensing range of this ultrasonic distance sensor?

The sensor has a working range of 55 mm to 250 mm, with a limiting range of up to 350 mm. The usable range can vary depending on the target’s size, orientation and reflective properties.

What supply voltage does it require?

It operates from a 10 V DC to 30 V DC supply. The unit is polarity protected and has a stated power consumption of up to 1.2 W with no load.

What output type does this sensor use?

This model provides two digital outputs with push-pull PNP/NPN behaviour. The outputs can be used for switching functions such as distance-to-object, window mode or object-between-sensor-and-background operation.

Does it have IO-Link capability?

Yes. The UC12-1223E sensor supports IO-Link V1.1 for process data, parameterisation, diagnostics and data retention functions.

What connector is fitted to the sensor?

The sensor uses a male M12, 4-pin connector. Compatible sensor/actuator cables with a female M12, 4-pin A-coded connector are typically used for connection.

What level of environmental protection does it provide?

The enclosure is rated IP65/IP67, making it suitable for many industrial environments where protection against dust and water ingress is required, provided it is installed with suitable mating connectors.

What are the main measurement performance figures?

Key performance values include a resolution of at least 0.1 mm, repeatability of ±0.15% and measurement accuracy of ±1%, based on the current measured value. It also includes temperature compensation to help maintain consistent operation.

How fast does the sensor respond?

The response time is 30 ms, with a switching frequency of 25 Hz and an output time of 8 ms. These figures make it suitable for many short-range object detection and positioning tasks.

What is the operating temperature range?

The operating ambient temperature range is -25 °C to +70 °C. The stated storage temperature range is -40 °C to +85 °C.

What are the physical dimensions of the sensor?

The sensor has a rectangular housing measuring 15 mm wide, 48.8 mm high and 43.5 mm deep. It weighs approximately 75 g.

What materials are used in the housing?

The housing is made from metal, specifically die-cast zinc. The ultrasonic transducer area uses polyurethane foam and glass-filled epoxy resin materials.

What indicator is built into the unit?

The sensor includes an LED indicator. The published technical information identifies status indication for the digital output and power state.

What applications is this sensor commonly used for?

This type of ultrasonic distance sensor is commonly used for short-range object detection, presence checking, level-related detection, positioning, distance monitoring and background suppression tasks in automated machinery and industrial equipment.

What accessories are commonly paired with this sensor?

Typical accessories include M12 4-pin sensor/actuator cables and suitable mounting brackets. For example, the SICK BEF-WK-W12 small stainless-steel mounting bracket is listed as a compatible mounting accessory for related compact sensor housings.
