The SICK WS/WE45-R650 (Part No. 1010996) is a long-range through-beam photoelectric sensor engineered for industrial environments where precision, speed, and durability are critical. Its design combines reliable relay switching output with superior detection range, making it suitable for large-scale applications such as perimeter monitoring, conveyor systems, outdoor automation, and industrial safety setups.

This model offers an impressive sensing distance of up to 300 meters, extendable to 350 meters under ideal conditions. Such capability ensures it can handle applications requiring detection over great distances, making it especially useful in logistics centers, warehouses, and outdoor industrial facilities where extended range is essential.

Performance is further enhanced by its fast reaction time of ≤ 500 microseconds and a switching frequency of up to 1,000 Hz. These specifications allow the WS/WE45-R650 to detect fast-moving objects accurately and transmit signals quickly, reducing delays in control responses. Unlike electronic-only output sensors, this version integrates a relay output, which makes it compatible with a wide range of control systems—including legacy systems—while offering reliable switching power for industrial processes.

Flexibility is also built into the sensor through its time-delay adjustment feature. Using a selector switch, operators can configure switch-on, switch-off, or combined ON/OFF delays. The timing can be set between 0.015 to 0.3 seconds for quick operations or extended from 0.5 to 12 seconds for processes requiring longer response intervals. This ensures the WS/WE45-R650 can be tailored to a wide array of operational requirements, from safety-critical detection to more controlled process timing.

Durability is a defining characteristic of this model. Constructed with a robust metal housing and rated IP65, the WS/WE45-R650 is dust-tight and water-resistant, allowing it to function reliably in tough industrial environments. It operates seamlessly across a temperature range of –25 °C to +55 °C, ensuring stable performance both indoors and outdoors. Furthermore, the sensor incorporates built-in protections against short-circuit, overload, and reverse polarity, enhancing its reliability and reducing the risk of unexpected downtime.

Additional usability features include status indicators that assist with alignment and operational checks, as well as secure connector options to simplify installation and ensure stable wiring. These practical features help operators and technicians maintain consistent performance and streamline setup.

In summary, the SICK WS/WE45-R650 delivers a combination of ultra-long range detection, fast relay-based response, configurable delay functions, and rugged environmental protection. This makes it an ideal choice for industries requiring dependable detection solutions that perform under challenging conditions and across extended ranges.
