This document introduces the product series of WORLD-BEAMTM photoelectric sensors, including QS18 compact self-contained photoelectric sensors and QS30 long-range opposed-mode sensors. These sensors feature small size, high performance, and reliability, and offer various detection modes and distances.
This document describes the Banner QS18 series of photoelectric sensors, covering small self‑contained, opposed‑mode, retro‑reflective, and fiber‑optic variants. It details electrical characteristics such as a 10 ~ 30 V dc supply, solid‑state complementary (SPDT) outputs selectable as NPN or PNP, and a maximum load current of 100 mA.
Installation instructions, wiring diagrams, and mechanical dimensions for each sensor type are included, along with optional accessories and connector options (Euro or Pico). The manual also introduces the QS18 Expert series and the related QS30 sensor line.
| Supply voltage | 10 ~ 30 V dc |
|---|---|
| Output type | Solid‑state complementary (SPDT), NPN or PNP selectable |
| Maximum load current | 100 mA per output |
| Response time (opposed mode) | ≤ 750 µs ON, 375 µs OFF |
| Repeatability (opposed mode) | 100 µs |
| Operating temperature (adjustable‑area mode) | 0 °C ~ 55 °C |
The QS18 sensor operates from 10 V to 30 V dc.
It provides a solid‑state complementary (SPDT) output that can be configured as either NPN or PNP.
The ON response is 750 µs and the OFF response is 375 µs.
Each output can drive up to 100 mA.
