Description
The Michigan Scientific SR__AW/E60/A Weatherproof Slip Ring and Encoder Assembly is used for applications requiring both a sealed slip ring and an encoder. It is designed to mount on the end of a rotating shaft, and make an electrical connection to strain gauges, thermocouples, or other rotating sensors, while simultaneously providing pulses to measure rotational speed. Specially designed seals provide complete weatherproof protection from water, dust, and other contaminants. The slip ring brushes and rings are made of precious metals, which minimize noise and enable the assembly to be used for low level instrumentation signals.
The SR__AW/E60/A accepts 0 to 10 circuit connections and incorporates a pulse encoder that enables rotational speed to be measured. The encoder generates a 60 pulse per revolution square wave signal with a range of 0 to 6,000 RPM. Since the pulses per second are equivalent to RPM, rotor speed can be recorded directly from a frequency display without scale conversion. Analog output signals for rotational speed can be obtained by using this slip ring and encoder model with Michigan Scientific’s frequency to voltage encoder electronics.
Connections to the slip ring rotor are made through a military style connector. For complete weatherproofing of this assembly, it must be used with a sealed metal cap or rubber boot to protect the terminals on the slip ring stator. Both of these options incorporate a military style connector, enabling all connections to the slip ring and encoder to be made through connectors. In addition, permanently lubricated bearings eliminate the need for routine cleaning and maintenance.
