The Model 30M is a compact, incremental encoder module with advanced magnetic sensing and signal processing technology. Featuring resolutions from 1 to 1024 CPR, commutation channels, several output types and two supply voltage options, it can be configured for a wide range of industrial, commercial and consumer feedback applications. With a noncontact magnetic sensor and optional sealing up to IP69K, the Model 30M can be applied in environments where dirt, dust and liquids are present.

Model

 N/A 30M

Type

 N/A Encoder Module

Input Voltage

 N/A 5 VDC ±10% fixed voltage
4.5 to 28 VDC (4.5 to 20 VDC over 105 ºC)

Input Current

 N/A 80 mA max, 50 mA or less typical with no output load

Output Format

 N/A Two square waves in quadrature with channel A leading B for clockwise magnet rotation as viewed from the encoder mounting face. Index gated to A and B.

Output Type

 N/A Open Collector
Open Collector with Differential Outputs
Differential Line Driver (Meets RS422 at 5 VDC)
Push-Pull
All outputs 20 mA max per channel

Maximum Frequency

 N/A 350 kHz

Electrical Protection

 N/A Reverse voltage and output short circuit protected.

Minimum Edge Separation

 N/A 20º electrical typical at 25 ºC
