The Seco-Larm E-931-S35RRQ Enforcer Photoelectric Beam Sensor is a high-performance infrared motion detector designed to enhance safety and automation for homes, businesses, and industrial sites. Whether you’re securing a garage entrance, monitoring a driveway, or controlling gate access, this advanced sensor provides dependable and accurate detection every time.
Using a powerful invisible infrared beam, the sensor detects any interruption in its line of sight, triggering an immediate response. This makes it ideal for applications like perimeter monitoring, vehicle detection, or automatic door systems. Unlike traditional motion sensors that rely on movement or temperature changes, the E-931-S35RRQ minimizes false alarms by using direct beam interruption technology — ensuring consistent performance in all lighting and weather conditions.
Engineered with IP66-rated weatherproof housing, the Enforcer is built to withstand harsh outdoor environments. From heavy rain to dust exposure, its durable construction ensures continuous, maintenance-free operation throughout the year. The adjustable sensing distance of up to 35 feet provides flexibility for different setups, making it suitable for residential driveways, warehouses, commercial entrances, and gate control systems.
The LED alignment indicators simplify setup and calibration, allowing installers to position and fine-tune the beam with ease. It supports a wide voltage range (12–240V DC / 24–240V AC) for seamless integration with a variety of automation, alarm, and security systems. The SPDT relay output enables direct connection to alarms, gate motors, and control panels without requiring additional components.
This sensor comes complete with reflector, mounting brackets, and all installation hardware, making setup quick and professional. Once installed, it operates silently and reliably, adding an extra layer of protection to your property without requiring regular maintenance.
Whether you’re automating a private entrance, adding safety to a commercial gate, or monitoring vehicle traffic, the Seco-Larm E-931-S35RRQ Enforcer delivers the performance, reliability, and versatility professionals trust.
