Seco-Larm E-931-S35RRQ Enforcer Indoor/Outdoor Wall Mounted Photoelectric Beam Sensor for sale $40 including shipping. I followed @neonturbo's awesome post about a garage door blockage indicator system. You can read about my installation here including pictures of the beam sensor installed.
The beam sensor comes with a 6 foot cord but I added 20 or so feet to it so it reached my garage door opener along the ceiling and I am including that additional length of cord as well.
The Seco-Larm beam sensor still works well, I just recently bought an Infinity Shield sensor and now using it with my blockage indicator system light instead since it covers a my entire garage door opening.
Again $40 for the Seco-Larm beam sensor including shipping or best offer. Please PM me if interested!
