New Futaba Telemetry RC Airplane Optical RPM Sensor 18MZ 14SG SBS01RO SBS01-RO

Description

This is the Futaba RPM Sensor (Optical type) For Futaba telemetry systems
Features:
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.
Includes:
One RPM sensor with attached cable
One plastic mounting bracket
Two pieces of double-sided foam tape
One instruction sheet
One warranty sheet
Requires:
Connection to S.BUS 2 system
Specifications:
Weight: 4.9g (0.173oz)
Voltage: 3.7 to 7.4 VDC

Foam tape
Length:  22mm   (7/8")
Thickness:  1.3mm  (1/8")
Comments:
This sensor will only work with S.BUS 2-compatible devices.
Helicopters: Because of the large rotor diameter, use of this sensor on a helicopter is not recommended. A magnetic sensor, such as the Futaba Magnetic RPM Sensor is suggested.
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.
