ME15 Magnetic Encoder Manual
Revision 1.1
Product Overview
The ME15 Magnetic Encoder is the newest addition to AMCI’s Encoder product line. The encoder is designed for
lower resolution and lower cost applications and provides 10 bits of resolution. The user has a choice either a SSI or 0
to 20mA, 4 to 20mA, 0 to 5V or 0 to 10V analog output. ME15’s small size, high reliability, IP67 protection rating and
low cost, make it an ideal replacement for potentiometers and small industrial encoders. Sturdy machined housing and
a high resistance to shock and vibration also make these encoders better able to withstand difficult environmental
conditions.
ME15 has two major components: A small diametrically polarized magnet and a custom ASIC which contains an array
of Hall sensors that generate a voltage when exposed to a magnetic flux field. The ASIC detects the change in
magnetic flux distribution as the magnet rotates above it delivers a voltage representing its angular position. The ASIC
cancels magnetic interference permitting it to operate in areas of high external fields. The encoder’s electronics
features a programmable device for converting the signals to a SSI-compatible bit stream.
The encoder is housed in an IP67 Size15 (1.5” dia) servo mount body with two options for shaft sizes - 1/4” and 6mm,
and two options for connections – through a 7-pin connector or built-in cable with flying leads of various lengths.
