This lot is SB46, a Koppert Machines stainless plug puncher / substrate ejector designed for high-volume propagation tray recycling in controlled-environment agriculture (CEA) operations.
The unit automatically ejects substrate plugs, soil, or rockwool remnants from used trays before they enter the washing line.
An integrated stainless conveyor moves trays under the pneumatic punch bank, while the Contrinex yellow IO-Link proximity sensor detects each tray and triggers the punch cycle, optimizing throughput and reducing unnecessary motion or downtime.
This wash-down-rated sensor is designed for precise, non-contact detection, and is IP68/IP69K certified for wet or humid environments — ideal for a tray washing room.
The system’s SCE control panel houses the electrical interface, and all controls are clearly labeled and ergonomically mounted for operator safety and efficiency.
