A quadrature encoder uses two output channels offset in phase to detect both direction and position with greater precision.

The IXARC rotary encoders now include housings that are only 27 mm long. This reduced length, combined with a diameter of only 36 mm, means that these super-compact devices are ideal for tight spaces.

Mercury 1500V (M1500V) digital output encoders are rated to 1 X 10- 8 torr of vacuum. The sensor is vented, rated for 48-hr bake out at 150°C, and works with both linear and rotary glass scales.
