Features

Full-open terminal block: The M3.5 screw terminal block provides accessible wiring space for easier installation and maintenance.
Through-beam sensing up to 30 m: NA-T30 and NA-T30F provide 30 m through-beam sensing, with 20 m and 10 m through-beam variants also available.
Wide AC/DC power range: All models support 24–240VAC/DC and provide a 1a relay output rated up to 3 A for resistive loads.
Selectable timer models: F-suffix models provide ON-delay, OFF-delay, one-shot, and timer-disabled operation with an adjustable 0.1–5 s range.
Interference-prevention models available: NA-T20RA, NA-T20RB, NA-T20RFA, and NA-T20RFB incorporate interference-prevention filters for multi-sensor installations.

Specification notes

F-suffix models include timer functions: NA-T20RF, NA-T20RFA, NA-T20RFB, NA-T30F, NA-M7RF, and NA-R10F provide ON-delay, OFF-delay, one-shot, and timer-disabled operation with a 0.1–5 s adjustment range.
NA-M7R sensing distance depends on the reflector: K-7 provides 0.03–7 m, K-71 provides 0.03–3.5 m, and S-510G provides 0.1–4 m.
Tighten the sensor body and mounting bracket to 0.8 N·m or less. The transmitter of through-beam models requires power wiring only.

FAQ

Q1: What is the TAKEX NA Series?
A: The NA Series consists of AC/DC power supply photo sensors with a full-open screw terminal block and integrated relay output.

Q2: What sensing methods are available?
A: The lineup includes through-beam, polarized retroreflective, and diffuse reflective sensing.

Q3: What is the maximum detecting distance?
A: NA-T30 and NA-T30F provide a maximum through-beam sensing distance of 30 m.

Q4: What is the detecting distance of NA-T20R?
A: NA-T20R and NA-T20RF provide 20 m sensing for opaque objects Φ22 mm or larger.

Q5: Can NA-M7R detect mirror-like objects?
A: Yes. NA-M7R and NA-M7RF use polarized retroreflective sensing and cover 0.03–7 m with the K-7 reflector.

Q6: Which NA models include timer functions?
A: NA-T20RF, NA-T20RFA, NA-T20RFB, NA-T30F, NA-M7RF, and NA-R10F include timer functions.

Q7: What timer modes are available?
A: Timer models provide ON-delay, OFF-delay, one-shot, and timer-disabled operation with an adjustable range of 0.1–5 seconds.

Q8: Which models include interference prevention?
A: NA-T20RA, NA-T20RB, NA-T20RFA, and NA-T20RFB incorporate interference-prevention filters.

Q9: What output and protection rating does the NA Series provide?
A: The series uses 1a relay output rated up to 3 A for resistive loads and has an IP66 protective structure.

Q10: What applications are suitable for the NA Series?
A: Applications include hopper material-level detection, carton length classification, conveyor systems, and vehicle height detection using the 30 m NA-T30.
