The SICK WS/WE45-R250 (Part No. 1010994) is a through-beam photoelectric sensor engineered to deliver reliable object detection over extended ranges in industrial environments. With its advanced infrared LED technology, this sensor achieves a sensing distance of up to 250 meters in standard use and can extend detection to 300 meters under optimal conditions. This long-range capability makes it a strong choice for large-scale applications, including outdoor perimeter monitoring, long conveyor belt systems, and heavy industrial automation setups where precise detection across great distances is essential.

One of its key performance benefits is the fast response speed. With a reaction time of ≤ 500 microseconds and a switching frequency up to 1,000 Hz, the WS/WE45-R250 ensures rapid detection of objects even in high-speed environments. Unlike other models in the same series that use electronic outputs, this version is equipped with a relay output, offering strong and reliable switching performance well-suited for direct control of mechanical or electromechanical systems. This feature enhances compatibility with older automation systems while maintaining precision and reliability.

Flexibility is another highlight of the WS/WE45-R250. An integrated time-delay selector switch allows operators to configure detection timing with ease. Switch-on, switch-off, or combined ON/OFF delays can be chosen to match process requirements. Delay ranges include 0.015 to 0.3 seconds for rapid operations and 0.5 to 12 seconds for longer control intervals. This flexibility enables tailored performance across diverse applications, whether the need is for immediate detection or for delayed triggering in complex sequences.

Durability is built into the design. The WS/WE45-R250 features a rugged metal housing that protects against the demanding conditions of industrial environments. With an IP65 protection rating, it is dust-tight and resistant to water jets, ensuring operational reliability even in harsh or outdoor conditions. It functions seamlessly across an ambient temperature range of –25 °C to +55 °C, providing stable performance under both cold and hot working climates. The sensor also incorporates essential electronic safeguards such as short-circuit, overload, and reverse-polarity protection, which not only extend its lifespan but also reduce downtime caused by electrical faults.

Ease of integration is another advantage. The WS/WE45-R250 is designed with straightforward connection interfaces and includes visible status indicators to assist with alignment and monitoring during operation. This user-friendly design ensures simple installation and dependable maintenance, helping operators maintain efficiency with minimal disruption.

In summary, the SICK WS/WE45-R250 offers a balance of long-range precision, high-speed detection, relay-based switching flexibility, and rugged construction. It is a reliable solution for industries that require durable and adaptable sensors capable of maintaining performance across wide distances and in challenging environments.
