Selectable 4-channel beam frequency (For E-964-D390Q model only)
The sensor beam frequency can be set at different levels on-site to avoid interference from other twin
photobeam sensors nearby. Useful during mutliple sensor applications as shown below. To select
between four different beam frequencies, adjust the beam channel switch of the transmitter side and
receiver side. See fig. 1 for switch location and table 2 for switch position.
Important – The transmitter and receiver sensor pair must be set with the same frequency.
