Carbon fiber-reinforced plastic housing – economical sensor solution.

The incremental compact encoders 3700 / 3720 with optical sensors are available with a resolution of up to 1024 pulses per revolution. The carbon fiber reinforced plastic housing of these incremental encoders is nevertheless extremely robust and resistant. Due to their high IP protection, they are also suitable for outdoor use.
