Frequently Asked Questions
How do I adjust the sensitivity on the Balluff BGL 20A Series Photoelectric Sensor?
The sensor comes with a potentiometer that allows you to adjust the sensitivity. You can turn the potentiometer to the minimum position for optimal small part detection, though this makes the sensor more sensitive to ambient light and contamination. Conversely, turning it to the maximum position will give you the greatest functional reserve but may limit small part detection.
What type of light does the sensor use and what is its wavelength?
The Balluff BGL 20A Series Photoelectric Sensor uses red light with a wavelength of 640 nm.
Can I use this sensor in applications where safety of personnel is a concern?
No, this photoelectric sensor should not be used in applications where the safety of persons depends on the device's function, as it is not designed as a safety component according to EU machine directives.
What is the maximum ambient light level the sensor can tolerate?
The sensor can tolerate a maximum ambient light level of 5 kLux.
What are the electrical specifications of the sensor?
The sensor operates with a supply voltage of 10 to 30 V DC, has an effective operating current of 200 mA, and a no-load current of less than 35 mA. It also features a switching frequency of 1500 Hz and is protected against short circuits and reverse polarity.
What is the switching frequency of the sensor?
The Balluff BGL 20A Series Photoelectric Sensor has a switching frequency of 1500 Hz.
What is the protection rating of the sensor?
The sensor has an IP67 protection rating, making it dust-tight and protected against the effects of immersion in water.
What materials are used in the construction of the sensor?
The sensor's housing is made of die-cast zinc, and the active surface is made of glass.
What is the operating temperature range for the sensor?
The operating temperature range for the sensor is from -10 to +60 degrees Celsius.
How can I switch between light-on and dark-on modes?
The sensor features a potentiometer that allows you to select between light-on and dark-on modes. Turn the potentiometer to the minimum position for dark-on mode, and to the maximum position for light-on mode. Avoid the grey area in between, as the setting is undefined there.
