Specification notes
Q1: What is the TAKEX DLN Series infrared type?
A: It is a fixed-field reflective photo sensor series using an 850 nm infrared LED with selectable BGS and FGS operation.
Q2: What models are available?
A: The lineup consists of DLN-S4V for short-range sensing and DLN-S20MV for middle-range sensing.
Q3: What is the detecting range of DLN-S4V?
A: DLN-S4V detects from 10 to 100 mm, with a setting range of 24 to 100 mm.
Q4: What is the maximum detecting distance of DLN-S20MV?
A: DLN-S20MV can detect targets up to 300 mm, with a setting range of 90 to 300 mm.
Q5: How does the infrared type differ from the standard DLN Series?
A: The infrared type uses an invisible 850 nm infrared LED and is suitable for targets that absorb visible red light.
Q6: Is it suitable where a visible sensing spot is undesirable?
A: Yes. It is intended for applications such as automatic faucets and gaming equipment where an invisible sensing spot is preferred.
Q7: Can BGS and FGS operation be selected?
A: Yes. BGS suppresses backgrounds beyond the setting distance, while FGS detects targets against a stable background.
Q8: Are both NPN and PNP outputs provided?
A: Yes. Both outputs are provided, but they must not be used simultaneously.
Q9: What are the response time and protection rating?
A: Both models provide a response time of 0.5 ms or less and IP67 protection.
Q10: What applications are suitable for the infrared DLN Series?
A: Applications include silicon wafer and wafer carrier detection, electronic components, printing processes, CD presence, tile and bobbin detection, no-touch switches, and targets that absorb red light.
