Seco Larm Photoelectric Beam Sensor E-931-S35RRQ 35ft Range

Description

Product Overview

The Seco Larm E-931-S35RRQ is a high‑performance photoelectric beam sensor designed for demanding industrial and commercial applications. Built with a rugged, weather‑proof enclosure, this sensor can withstand temperatures up to 55 °C and exposure to rain, dust, and direct sunlight, making it ideal for both indoor and outdoor installations. The device creates an invisible infrared beam that spans up to 35 feet (approximately 11 meters), providing a reliable detection zone for a wide range of security and automation scenarios. Its compact dimensions—5.75 × 3.5 × 2 inches—and lightweight construction (11.2 oz) allow for flexible mounting on walls, poles, or other structures. Powered directly from a standard AC outlet, the sensor eliminates the need for batteries, reducing maintenance costs and ensuring continuous operation. The integrated LED indicator offers a clear visual cue of power status, while the adjustable sensing distance lets users fine‑tune the detection range to match specific site requirements. Compatibility with garage door openers, security systems, and industrial automation equipment further expands its versatility, positioning the E‑931‑S35RRQ as a go‑to solution for reliable beam detection.

Usage

Designed for a broad spectrum of environments, the Seco Larm beam sensor excels in applications where precise, non‑contact detection is essential. In residential settings, it can be installed above garage doors to trigger automatic opening or closing mechanisms when a vehicle passes through the beam. Commercial facilities often employ the sensor to monitor loading dock doors, ensuring that forklifts and pallets do not inadvertently breach safety zones. Outdoor gate security benefits from the sensor’s long‑range detection, allowing property owners to set up perimeter alarms that activate when an intruder interrupts the infrared line. Industrial automation lines use the sensor to count items on conveyor belts, verify product presence, or synchronize robotic arms without physical contact. Because the unit is wall‑mountable and powered by a standard outlet, installation is straightforward: simply attach the mounting brackets, plug the sensor into a nearby socket, and align the transmitter and receiver to create the desired detection plane. The sensor’s robust construction guarantees reliable performance even in harsh weather, making it suitable for agricultural barns, parking structures, and remote outdoor installations where other sensors might fail.

FAQ

How do I adjust the sensing distance?

The sensor includes a built‑in potentiometer that lets you fine‑tune the detection range. Turn the adjustment knob while observing the LED indicator until the desired distance is reached. Detailed instructions are provided in the user manual.

Can the sensor be used with existing security systems?

Yes. The E‑931‑S35RRQ outputs a standard dry‑contact signal that can be integrated with most alarm panels, access control units, and automation controllers. Wiring diagrams are included to simplify the connection process.

Is the sensor compatible with battery‑backed UPS systems?

While the sensor is designed for direct AC power, it can be connected to an uninterruptible power supply (UPS) that provides AC output. This setup ensures continuous operation during power outages.

What maintenance is required?

Because the unit is sealed and powered by the mains, routine maintenance is minimal. Periodic visual inspections to ensure the lens is clean and free of obstructions are recommended. No battery replacement is needed.

What is the warranty period?

Seco Larm offers a one‑year limited warranty covering defects in materials and workmanship. Additional extended warranty options are available through authorized distributors.
