Product Description:

The 11RC-300-J-38/3 resolver serves the purpose of converting the mechanical rotation of a motor into corresponding electrical signals that reflect the angular position. It is manufactured by Danaher which has established itself as a leading force in mechanical technology and industrial innovation.

The 11RC-300-J-38/3 resolver belongs to the group of rotary feedback devices where it serves to offer precise angle measurements in industrial automation systems. It accepts two-phase stator input power through an excitation signal of 11.8 volts at 400 Hz that enables stable power delivery. The rotor output consists of two phased electrical signals which translate shaft position into an electrical format and serves as a requirement for closed-loop servo systems. The Dynapar series resolver demonstrates a compact structure by establishing itself as the shortest mounting length among its class because it facilitates easy installation in spaces with size restrictions. The device operates correctly within both low temperature ranges of -55°C along with high temperature ranges of +125°C that provide support for various thermal applications. The 0.36 kg weight makes this device suitable for numerous servo-based setups where it maintains an ideal balance between weight and compatibility with various mechanical frames.

The 11RC-300-J-38/3 resolver’s temperature tolerance enhances reliability in systems where variable climates or prolonged operation is needed. It is rated for use at altitudes up to 1000 meters above sea level by supporting installation in mid-elevation zones. The unit works with 95% relative humidity which aids in making it appropriate for setups where condensation is controlled but moisture is present. The resolver carries CE marked by ensuring certification with relevant industry safety and electromagnetic proper standards.
