EMS22 Non-Contacting Magnetic Rotary Encoders

Bourns EMS22 are non-contacting rotary magnetic encoders with a Hall Effect application-specific standard product (ASSP) capable of producing four distinct output waveforms. These waveforms include 2-bit quadrature up to 256 Pulses per Revolution (PPR), Step/Direction up to 512 PPR, Pulse-Width Modulated (PWM) output with 1024 positions, and Absolute with 1024 positions. Model EMS22 is available in both a 3.3V_DC and 5V_DC supply voltage and is offered in two different versions. These encoders have the capability of rotating up to 10,000RPM while maintaining code accuracy, making them suitable for MMI applications such as industrial automation. This performance is achieved by utilizing dual ball bearings in the construction of each device, resulting in extended rotational life up to 100,000,000 shaft revolutions. The EMS22 non-contacting encoders are ideal for use in harsh environments where extreme levels of temperature, moisture, and particles are present. Their outstanding performance is attributed to the non-contacting technology and superior performance of the AS5040 Hall Effect ASSP. These encoders are sealed to IP65 (ingression protection) with an optional upgrade to IP67.
