ME15 Absolute Analog Rotary Shaft Encoder
Description
AMCI ME15 Absolute Analog Rotary Shaft Encoder
AMCI's ME15 Analog rotary shaft encoder is designed for cost sensitive applications that require bullet-proof reliability. The ME15 magnetic encoder measures just under 1.5" in diameter and is engineered for heavy-duty operation across a variety of industries. The encoder's IP67 rating protects against dust and moisture, and the sensor's compact design only relies on two components, ensuring trouble free operation.
AMCI's ME15 Analog encoder utilizes a small diametrically polarized magnet and a custom ASIC that contains an array of Hall sensors that generate a voltage when exposed to a magnetic field. The ASIC detects the change in magnetic flux distribution as the magnet rotates above it and outputs a voltage level that represents the angular position. The ASIC also has the ability to ignore any interfering magnetic fields, allowing the ME15 to operate in areas of high external fields.
Summary: The ME15’s small size, high reliability, IP67 protection rating and low cost make it an ideal replacement for potentiometers and small industrial encoders. A sturdy machined housing and a high resistance to shock and vibration make these encoders an ideal fit and capable withstanding difficult environmental conditions, including electromagnetic interference (EMI) noise generated by neighboring currents.

The Analog output version of the ME15 can be ordered to output its minimum to maximum output over the four Angular Ranges listed above. However, the next minimum to maximum cycle always begins at the start of the next full turn.
The following diagrams show the output waveforms for the four angular ranges of an encoder ordered with CW increasing output.
