Elevator photocell WECO-917B71
The WECO-917B71-AC220 is a high-density universal elevator light curtain system manufactured by WECO.
Compared with the earlier 917A61 series (17 diode groups / 94 beams), the 917B71 is an upgraded high-sensitivity model with significantly enhanced detection capability. It is widely used in elevator modernization, maintenance, and retrofit projects for commercial and residential buildings.
