Frequently Asked Questions
What is the sensing range of this ultrasonic sensor?
The E4C-UDA41 offers a variety of sensing ranges depending on the sensor head model used. For instance, the E4C-DS30 model has a sensing range of 50 to 300 mm, the E4C-DS80 model ranges from 70 to 800 mm, and the E4C-DS100 model from 90 to 1,000 mm.
Can this sensor be used to detect transparent objects?
Yes, the E4C-UDA41 is capable of detecting transparent objects as well as objects of various colours and materials, including metallic and non-metallic surfaces.
Is the sensor head of the E4C-UDA41 series waterproof?
Sensor heads in the E4C-UDA41 series, such as the E4C-DS30, E4C-DS80, and E4C-DS100, are rated at IP65, making them suitable for use in environments where they may be exposed to dust and moisture.
What type of output does the E4C-UDA41 provide?
The E4C-UDA41 provides a PNP output, and there are also models available with NPN output or with an analog output ranging from 1 to 5 VDC.
How can I adjust the sensing range of the E4C-UDA41?
The E4C-UDA41 features a scaling function that allows you to set threshold values directly using position teaching with a workpiece or by using distance without a workpiece.
What is the response time of the E4C-UDA41 sensor?
The response time of the sensor depends on the sensor head model and the number of operations set to average. For example, the E4C-DS30 has a response time of 30 ms when set to an average of 256 operations.
Can I mount two E4C-UDA41 sensors side by side?
Yes, you can mount two or more E4C-UDA41 sensors side by side, but you must ensure that the minimum distances specified in the datasheet are maintained to avoid mutual interference.
What materials are the sensor heads made of?
The sensor heads of the E4C-UDA41 series are made with a nickel-plated brass case and an oscillator surface composed of glass epoxy resin and polyurethane.
How do I know if the sensor is within the sensing range?
The sensor heads are equipped with an indicator that lights up yellow to show that the ultrasonic sensor is within the sensing range.
What should I do if the sensor is not detecting objects correctly?
If the sensor is not functioning as expected, you may need to recalibrate it using the one-touch teaching feature to remove the effect of the background or adjust the threshold settings.
