Specification notes
Q1: What is the TAKEX PU Series?
A: The PU Series consists of U-shaped through-beam embedded amplifier photo sensors with the emitter and receiver integrated into one housing.
Q2: What models are available?
A: The current lineup includes PU5 and PU10.
Q3: What is the main difference between PU5 and PU10?
A: PU5 has a fixed 5 mm sensing gap, while PU10 has a 10 mm gap. Their target size, output, response time, cable, and protection rating also differ.
Q4: What is the minimum target size for PU5?
A: PU5 detects opaque objects Φ1 mm or larger.
Q5: What is the minimum target size for PU10?
A: PU10 detects opaque objects Φ2 mm or larger.
Q6: What are the response times?
A: PU5 responds within 200 μs, while PU10 responds within 50 μs.
Q7: What outputs are provided?
A: PU5 provides an NPN open-collector output. PU10 provides current and voltage outputs.
Q8: Are both Light-ON and Dark-ON signals available?
A: Yes. Both models provide separate Light-ON and Dark-ON output leads. Any unused output lead should be insulated.
Q9: Do PU5 and PU10 have the same protection rating?
A: No. PU5 is rated IP67, while PU10 is rated IP40.
Q10: What applications are suitable for the PU Series?
A: Applications include general machinery, logistics, precision machinery, and electronic equipment, including stacker-crane positioning, address reading, rotation counting, and RPM measurement.
