    FAQ
    ❯

    A: This ultrasonic detection sensor offers 3 independent outputs, each rated at 100 mA with short‑circuit and overload protection. It supports both NPN and PNP output types, and both NO (normally open) and NC (normally closed) functions. The 3 outputs can be used for multi‑stage detection, status feedback, or redundant alarms—making it highly flexible for complex industrial control systems. The voltage drop is ≤3 V, ensuring clean signal levels.

    ❯

    A: This ultrasonic detection sensor has a response delay of approx. 15 ms and a release delay of approx. 15 ms (which can be shortened as required). The function input accepts a pulse width of ≥100 ms, with an input impedance of ≥4 kΩ, allowing external triggers for teach‑in, synchronization, or mode switching. The fast 15 ms response makes it suitable for high‑speed automated lines where rapid part detection is critical.

    ❯

    A: This ultrasonic detection sensor operates on 18 to 30 V DC with a ripple of 10 %pp, making it compatible with standard 24 V industrial power supplies. The no‑load current is <50 mA, and the rated operating current is 3 × 100 mA (one per output), with full short‑circuit and overload protection. It must be supplied by a Class 2 power source per the C‑UL listing, ensuring safe and reliable operation in industrial control cabinets.
