System Summary
SAM 4642 is a navigation 2 axis electromagnetic speed log for measuring longitudinal and transverse speed through water. A mile contour is included. Speed information can be relayed to a radar, AIS, VDR and all other relevant devices via NMEA-format connections. Interfaces between the operator unit, electronic unit and sensor comply with IEC 61162 specifications. All relevant IMO requirements are met or exceeded.

Sensor and Transceiver
SAM 4642 sensor is connected to the electronic unit located within 40 m of the sensor. The connection from the sensor to the electronic unit is via a serial RS-422 data link as well as the connection from the electronic unit to the operator unit. The link between electronic unit and operator unit may be up to 300 m. Power supply is via 230 VAC/115 VAC or 24 VDC. The power consumption is approximately 100 Watts.
