The SE Quadrature Dual-Shaft Encoders combine the most routinely-
used features in one standard device, and are available with a selec-
tion of five different resolutions (pulses/revolution).
The cube-style unit uses an infrared light source and precision
mechanical components to provide exact, repeatable counts.
Mounting the encoder is quick and easy using the pre-drilled holes in
the base flange, or the housing mounting holes located at each shaft
output. This encoder can be used as a direct replacement for other
brand encoders, with no blind holes to drill. The double-ended, flat-
keyed shaft permits a choice of mounting positions. Chrome steel
bearings provide 20% longer life than stainless steel bearings.
To aid in troubleshooting, LEDs are located directly on the body to
instantly verify correct output operation. Quadrature output is standard
and can be externally scaled to provide any engineering unit (RPM,
angular position, feet/min., etc.). Gold-plated connectors ensure max-
imum signal transfer. Very low power consumption; typical current
draw, 35mA @ 15DCV.
