Optical-Data-Transfer-Unit

Space Optical Data Transfer Unit provide a means to transfer data between points  thru. Near-infrared rays without laying cable.

There are different communication options available;

– Parallel communication

– Ethernet

– CC-Link 

Since light is used as a transmission medium, there is no chance that data transmission is disturbed by electromagnetic field. 

Space Optical Transfer Unit (Parallel type)
SOT-NP / SOT-FP series

SOT-NP40 / NP80 series
Parallel 4bit / 8bit type
SOT-FP80 series
SEMI E84 compliant
Parallel 8bit type

The following models are available.

  • SOT-NP401 / 403                            Parallel 4bit,  Transmission distance 1m / 3m
  • SOT-NP801 / 803                            Parallel 8bit,  Transmission distance  1m / 3m
  • SOT-FP801 / 803 / 805  *1)            Parallel 8bit,  Transmission distance  1m / 3m / 5m

*1) SEMI E84 compliant.

The parallel type space optical transfer unit allows a pair of devices to transmit and receive data alternately in the half duplex, bi-directional mode.  
Space Optical Transfer unit is widely used in transmitting control signals for Automatic Guided Vehicles (AGV) and other applications.  

Applications for Parallel SOT-NP / SOT-FP series

Automatic Guided Vehicle (AGV)

Body welding line

Information on Interlock signal of the process and indicating destination etc. are communicated between each station and AGVs. 

Presence of material, confirmation signal, control signal can be communicated.

Space Optical Transfer Unit (Ethernet communication type)
SOT-ES series

SOT-ES100 series
Ethernet (IEEE802.3) compliant
Transmission distance  100m

The following models  are available.   

  • SOT-ES100               Ethernet (IEEE802.3) compliant,  Transmission distance 100m
  • SOT-ES200               Ethernet (IEEE802.3) compliant,  Transmission distance 200m

The wireless infrared Ethernet connection enables high capacity communication without   compromising data quality. 

Applications for SOT-ES series

Space Optical Repeater for CC-Link
SOT-MS / SOT-MQ series

SOT-MS102 series
Transmission distance 100m
SOT-MQ82 series
Transmission distance 80m

The following models are available.     

  • SOT-MS102    CC-Link ver 1.10/ver 2.00 compliant,   Transmission distance 100m
  • SOT-MS202    CC-Link ver 1.10/ver 2.00 compliant,  Transmission distance 200m
