MECHANICAL INSTALLATION
1.0 Description
The NextGen RT 6200 is a high performance and
reliable Digital Tachometer, designed to provide
position and velocity feedback from both AC and DC
electric motors with pulse counts ranging from 60
through 2048 pulses per revolution. The RT 6200
utilizes rugged ductile iron casting construction and
provides interchangeable sensor modules and
magnetic technology capable of withstanding the
harshest industrial environments. This ensures
precise and consistent digital motor speed feedback.
The encoder is mounted in a variety of ways and
utilizes a patented, heavy-duty, one piece, magneto-
resistance sensor module with encapsulated surface
mount electronics. The encapsulation provides
resistance to water, oil mist, dirt, high temperatures,
and other harsh environments. The sensor module
includes a 10-pin quick connector requiring only a
screwdriver for final electrical installation. The non-
contact magnetic sensor and rugged magnetized
pulse wheel are designed and machined to function
properly without any adjustments. The RT 6200
provides precise, reliable speed signals for many
monitoring and control applications, and is a standard
feedback device for AC and DC variable speed
drives. The unit is bi-directional providing square
wave outputs.

2.0 Preparation
The RT 6200 utilizes a modular construction that
permits the user to configure the unit as a one or two
signal output tachometer. Sensor modules are
universal and interchangeable. If one output requires
replacement, simply remove four screws, and
replace with a new sensor module. No electrical
adjustment or alignment is required. After unpacking
the unit and verifying receipt of the items listed in the
packing list, you may proceed with mechanical
installation.
The encoder has no user maintainable components.
The bearings are permanently lubricated and sealed
for the operational life of the unit. The Pulse Wheel
also needs no service. Disassembly of the unit will
void the Warranty. The magnetic sensor and elec-
tronics modules need no adjustment, but can be
replaced by the user in case of failure.
2.1 Painting Considerations
The enclosure may be painted. Please pay
attention to the following considerations.
NOTE
Corrosion preventative coating has been
applied to the enclosure. Standard
degreasing practices must be followed
before applying paint.
Connector/Hood
• Do not hinder the latches on the connector
if the connector is painted.
• If the enclosure is painted before the
sensor module(s) is added, be sure to
mask off the area where the sensor
module(s) will be placed. The module must
mate directly to the enclosure with nothing
between. Failure to do this will degrade the
alignment of the system and may cause it
to fail.
• Ensure excess paint runoff does not clog
enclosure drain holes.
