OMRON Rotary Pulse Indicator K3HB-R Series

OMRON Rotary Pulse Indicator K3HB-R Series Digital Rotary Pulse Meter Capable of 50 kHz Measurements ? Visual confirmation of judgement results through display colors that switch between red and green. * 1 ? Measures High-speed Pulses at 50 kHz. Provides high-speed pulse measurements up to 50 kHz of rotary encoder or ON/ OFF pulse signals and can perform rotating measurement of high-speed rotating objects. Note: No-voltage contacts of up to 30 Hz are supported. ? Six Measurement Operations Including Rotation ( rpm) / Circumferential Speed, Ratio, and Cumulative One Rotary Pulse Meter has 6 rotary pulse measurement functions to support a variety of pulse measurement applications. Select the best function for your application from the following: Rotation ( rpm) / circumferential speed/ instantaneous flowrate ( value proportional to frequency) , absolute ratio, error ratio, error, flow rate ratio, and passing speed ( value inversely proportional to frequency) . Specifications ? Ratings Note: 1. DC power supply models require a control power supply capacity of approximately 1 A per Unit when power is turned ON. Particular attention is required when using two or more DC power supply models. The OMRON S8VS-series DC Power Supply Unit is recommended. 2. PNP input types are also available. 3. For K3HB-series DeviceNet models, use only the DeviceNet Connector included with the product. The crimp terminals provided are for Thin Cables.
