These are miniature single-circuit, change-over relays providing full broadcast quality switching, for data rates up to 12Gb/s. They are suitable for applications such as power-failure switching and source selection. They can be used to choose between two inputs or to have a single input and choose between two outputs, controlled by a 5V DC applied to the coil.

Three models are available: L4KR01 is for use with full 12G/4K UHD SDI video and all lower standards including 6G, 3G, HD and SD SDI. L3GR01 may be used with 3G, HD or SD SDI signals while LHDR01 may be used with HD or SD SDI. Each is built in an ABS enclosure fitted with three female BNC connectors, with mounting screws, which are also used to connect to the coil, on the same face of the relay as the connectors.

All LEN Video Relays can also be used with the ASI format.

Dimensions: 45 x 30 x 15 (l x w x h) mm, excluding connectors.

Optional accessories: LMPR01 rack frame is a 1U 19-inch panel, finished in black, punched to take eight relays mounted from the rear by means of the mounting screws, the BNC connectors facing out of the rack. If it is desired to have the connectors facing into the rack, the relays may be reversed, revealing the relay modules which will protrude 15mm from the surface of the panel.
