Specification notes
Q1: What is the TAKEX NT30F?
A: NT30F is a 30 m long-range through-beam embedded amplifier photo sensor with transmitter and receiver self-diagnostic functions.
Q2: What is the detecting distance of NT30F?
A: The detecting distance is 30 m for opaque objects Φ22 mm or larger.
Q3: How does the self-diagnostic function work?
A: The transmitter provides check input and normal monitor output, while the receiver provides an alarm output when received-light stability falls below the stable level.
Q4: Is Light-ON/Dark-ON operation selectable?
A: Yes. The receiver includes a switch for selecting Light-ON or Dark-ON operation.
Q5: What outputs does NT30F provide?
A: It provides current and voltage control outputs together with an NPN open-collector alarm output.
Q6: Can an earphone be used for optical-axis adjustment?
A: Yes. The receiver includes an earphone jack for monitoring received light during optical-axis alignment.
Q7: What is the difference between NT30F and NT30FW?
A: Both provide 30 m self-diagnostic through-beam sensing. NT30FW adds a water-cooling jacket and supports ambient temperatures up to +110°C.
Q8: Can pinhole plates be used with NT30F?
A: Yes. 30P1, 30P3, 30P5, 30P7, and 30P10 are available, with different aperture sizes and detecting distances.
Q9: What is the protection rating?
A: Both NT30F and NT30FW provide IP66 protection.
Q10: What applications are suitable for NT30F?
A: It is suitable for metal-processing and large conveyor applications, including detecting loose or hanging wire rods with pinhole plates.
