System Sensor 2WTR-B Photo Detector Plug-in 2‑Wire Sensor White

Description

Product Overview

The System Sensor 2WTR-B is a purpose‑built photoelectric detector that combines simplicity with robust performance for demanding industrial environments. Engineered with a compact 2‑wire architecture, the device eliminates the need for external power supplies, drawing power directly from the control circuit while maintaining consistent signal integrity. Its white, ceiling‑mountable housing blends seamlessly into cleanroom, warehouse, and production line settings, offering unobtrusive visual alarm indication when an object interrupts the light beam. The sensor operates on a thermal style detection principle, providing rapid response times and high reliability even in the presence of dust, moisture, or temperature fluctuations up to 135 percent relative humidity. With a lightweight design of just 0.62 pounds and dimensions of 6 × 6 × 2 inches, installation is straightforward, and the device can be positioned at heights that maximize coverage while minimizing blind spots. The visual alarm feature utilizes an integrated LED indicator, delivering immediate on‑site feedback without the need for additional external alerting components. Technical specifications such as a part number of S2WTRB, UPC 742779300218, and ASIN B09F8MTGZL ensure traceability and easy sourcing for maintenance teams. Customer reviews consistently highlight the sensor’s durability and ease of integration, reflecting its position as a top‑ranked product in the Photoelectric Sensors sub‑category.

Usage

Designed for a wide range of industrial applications, the 2WTR‑B excels in environments where continuous monitoring of material flow, conveyor belts, or personnel movement is critical. In manufacturing plants, the sensor can be mounted above assembly lines to detect the presence of components, triggering automated stoppage or diversion mechanisms to prevent jams and ensure product quality. Warehouse managers benefit from its ability to monitor pallet positions, alerting staff when items are improperly stacked or when a loading dock becomes congested. The sensor’s battery‑free operation makes it ideal for installations where power access is limited or where maintenance intervals must be minimized, such as in remote processing facilities or outdoor sorting stations protected by a weather‑sealed enclosure. Its visual alarm provides an immediate, on‑site cue that can be seen by operators without requiring additional auditory or networked alerts, reducing response times in safety‑critical scenarios. The ceiling‑mount design also allows the detector to be positioned above hazardous zones, keeping personnel away from moving machinery while still maintaining accurate detection coverage. Compatibility with standard industrial control systems ensures seamless integration into existing PLC or SCADA architectures, enabling real‑time data collection and remote monitoring when paired with appropriate interface modules.

FAQ

Can the sensor be used in outdoor environments?

Yes, the 2WTR‑B is built to operate in harsh conditions, including outdoor installations, as long as it is protected from direct exposure to rain or extreme temperatures. Adding a suitable enclosure or mounting bracket can extend its suitability for outdoor use.

What type of power source does the sensor require?

The detector draws power directly from the connected control circuit through its two‑wire interface, eliminating the need for an external battery or power adapter. This simplifies wiring and reduces maintenance requirements.

How does the visual alarm indicate a detection event?

When the photoelectric beam is interrupted, an integrated LED within the sensor illuminates, providing a clear visual cue that an object or person has crossed the detection zone. The alarm can be observed from a distance, aiding rapid response.

Is the sensor compatible with existing PLC systems?

Yes, the 2WTR‑B outputs a standard signal that can be interfaced with most programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA) systems. Documentation includes wiring diagrams to facilitate quick integration.

What warranty coverage is provided?

System Sensor offers a one‑year limited warranty covering manufacturing defects. During this period, any faulty unit will be repaired or replaced at no additional cost, and technical support is available throughout the warranty term.
