Futaba telemetry system SBS - 01RO RPm sensor optical type

This is the Futaba RPM Sensor (Optical type) For Futaba telemetry systems FEATURES : Compatible with the Futaba 18MC-WC, 18MZ, 18SZ, 14SG, 10J, 6K, This sensor, when used in conjunction with a telemetry-enabled radio system, is used to indicate the rotation speed of a propeller, rotor, or other component. Nothing needs to be attached to the component since the sensor uses available light reflected off that component. REQUIREMENTS : Connection to S.BUS 2 system SPECIFICATIONS : Weight: 4.9g (0.173oz) Voltage: 3.7 to 7.4 VDC Range: 360 to 300,000 RPM/Fin(s) Sensor, length, overall: 6-1/4\ (160mm) width: 28mm (1-1/8\) height: 13mm (1/2\) Mounting bracket, length: 34mm (1-3/8\) width: 26mm (1\) height: 12mm (1/2\) Foam tape, length: 22mm (7/8\) width: 22mm (7/8\) thickness: 1.3mm (1/8\) COMMENTS : This sensor will only work with S.BUS 2-compatible devices. Brightness : Adequate light is needed for this sensor to operate properly. Conditions such as dusk, dawn, clouds, indoor operation, poor angle-of-reflection off of propellor or fin, etc., will result in a measurement of 0 RPM. Installation: It is recommended that the sensor be mounted at or less than 150mm (6\) from the object whose rotation speed is being measured. The closer to the object the sensor is mounted, the more reliable the measurements will be. Set-up: The default slot number for this device is 2. Information on changing the slot number can be found in the transmitter manual. This device also has a default S.BUS 2 ID number which will need to be changed if more than one SBS-01RO sensore is attached to the same S.BUS network. The default ID number can be found on the side of the unit.
