LiftMaster CPS-U Commercial Protector System Safety Sensor Kit

The LiftMaster CPS-U (Commercial Logic Protector System – Universal) is a new, genuine OEM safety reversing sensor kit designed for commercial and industrial door operators. The kit consists of two photo-eye sensor heads (part numbers 001D6857-1 and 001D6857-2) using Industrial Code Technology and marked CDO 2010 Ready, providing UL 325-compliant entrapment protection by transmitting an infrared beam across the door opening — if the beam is broken while the door is closing, the operator reverses immediately. Included hardware consists of two stamped-steel adjustable mounting brackets (stamped Q12D403), a set of mounting angle brackets, a hardware bag with bolts, nuts, and a nylon insert lock nut, and the pre-wired sensor lead assemblies with hook-end strain relief wires. The CPS-U is compatible with LiftMaster, Chamberlain, and Craftsman commercial door operators that support the Commercial Protector System input, including CSL24V, CSW24V, SL3000, and related series. Country of origin is Mexico per the factory label; DOM on the pictured sealed unit reads Oct-30-2025.
