The standard MERLIN consists of a control and a set of columns (one transmitter and one receiver) and a set of interconnecting cables. The MERLIN will also accept multiple sets of columns per control box to protect more than one side. Thus, the benefit of reducing the cost for an application like guarding straight-side presses, etc.

How it works?

  • The Merlin light curtain is a solid-state electro-optical switch intended for use as a control device on production machine. Merlin produces and checks an invisible network of closely spaced, pulsed, infrared light beams between separate transmitter and receiver columns. As long as conditions are normal and all beams are received, the output relay contacts remain closed. If any beam is not found they open, thereby stopping the machine and protecting the operator.


  • In summary, this more-robust "T" series design has the following features: Class 4 safety system Very Rugged Aluminum extrusion housing 2"x1.75".
  • Circuit boards utilize surface mount technology to provide compact size as well as a high degree of reliability.
  • Metallic Connectors on Columns, controllers and cables Red indicator LED's at each photocell on the receiver.
  • Mechanical locking tabs between each 6" internal Circuit board for high shock applications, yet still providing for field serviceability Improved column mounting brackets with rotary adjustment capability.
  • Three year Warranty.
