The Genie 20302R.S Pre Series II STB Pigtail Connector is a genuine OEM service adapter designed for Genie garage door openers that use the Safe-T-Beam (STB) photo-eye safety system and were manufactured prior to the Series II wiring style. This short harness provides the proper interface for the Safe-T-Beam circuit on older Genie powerheads, making it useful when replacing or upgrading photo eyes so the safety reversing system operates as intended. By bridging the connection between legacy opener terminals and the STB leads, it helps restore reliable door-reversal protection whenever an obstruction is detected.
Intended for residential Genie openers equipped with Safe-T-Beam technology, the 20302R.S is used during repair or retrofit work where the powerhead’s earlier connection scheme requires an adapter lead. Installation is straightforward for low-voltage control wiring: disconnect power, follow the opener’s service manual for the Safe-T-Beam terminals, make secure connections, and verify sensor alignment and indicator LEDs for proper operation. Because compatibility varies by model and production year, consult your opener’s parts list or manual to confirm that 20302R.S is the specified Pre Series II STB pigtail connector for your unit.
