Seco-Larm Photoelectric Sensors Editorial Review
The Seco-Larm E-931-S50RRGQ reflective photoelectric beam sensors have garnered a mixed reception from customers. Users appreciate the effective sensing range of up to 50 feet and the sensor's capability to operate well in ideal conditions. Many report successful use for driveway alarms, noting that with proper setup and adjustments, the sensors performed reliably. However, several customers have raised concerns regarding false triggering in adverse weather conditions, particularly during rain and morning dew. These issues seem to be linked to the alignment of the sensor and reflector, as well as the performance of the reflector when wet. Some users suggest that additional reflectors may mitigate these problems to some extent. Furthermore, while setup may take some time, several users still affirm that the effort is worthwhile, especially when it enhances security around driveways or automated gates. Yet, it’s clear that the product could benefit from better customer guidance regarding installation and the limitations in less-than-ideal weather conditions. Overall, the Seco-Larm sensors deliver commendable performance under optimal conditions, but potential buyers should Consider the trade-off between functionality in poor weather and the need for sensitive alignment and adjustments. **
