Restore rock-solid “cat-in / cat-out” detection on the original Leo’s Loo (v1). This matched pair of factory sensors plugs directly into the main board, so every cycle pauses the instant whiskers cross the doorway—no false starts, no surprises.

Key Benefits

Exact OEM fit – engineered for Leo’s Loo v1 only; not compatible with Leo’s Loo Too.

Plug-and-play harness – color-coded connector and pre-terminated leads mean a five-minute swap—no soldering or calibration.

Precision dual-beam array – reliably senses cats as light as 1 lb / 0.5 kg to prevent mid-cycle rotation.

Dust-sealed optics – clear epoxy lens and gasket keep litter, dander, and moisture off the diode for long-term accuracy.

Low-power, long-life emitters – industrial-grade components rated for 50,000+ hours of duty.
