8 Specifications and Accessories
An EZ-SCREEN Type 2 System includes a compatible emitter and receiver (equal length; available separately or in pairs), and two cables.
Mounting hardware is included with each emitter and receiver. Interfacing solutions include IM-T-.. modules, or redundant positively
guided contactors; see
