Product catalog summary

Overall Dimensions and Performance:
The document outlines the performance specifications of a gearmotor with a 24 V DC motor, noting that a 12 V DC motor would result in a 10% reduction in linear speed and double the electrical consumption. The gearmotor can achieve a maximum torque of up to 15 Nm and features an IEC 63B14 output flange, aluminum housing, and standard IP 65 protection. The motor is typically mounted in a right-hand position but can be optionally mounted on the left-hand side.

Encoder Specifications:
The gearmotor includes a 2-channel bidirectional magnetic encoder for positioning and speed feedback, directly fitted on the motor shaft. The encoder is available in two resolutions: 1 pulse per revolution (ppr) with code GI 21 and 4 ppr with code GI 24. The encoder's impulses per 10 output turns vary based on the selected ratio.

Ordering Code Example:
An example ordering code is provided: MR 31 RL CC 24 V GI 21 LH, which specifies the gearmotor, selected ratio, motor, encoder, and options.

Encoder Details for Linear Actuators:
For linear actuators, the document describes the Encoder GI and Encoder EH38. Encoder GI operates with 5 to 24 Vdc and has a 5-wire cable function, while Encoder EH38 is a hall effect, bi-directional, incremental encoder with 100 pulses per revolution and a zero set pulse. Both encoders are protected against polarity inversion and incorrect output connections.

Safety and Protection:
The document notes that the safety clutch FS cannot be used with a rotative encoder as it would cause the position reference to be lost due to slipping. Additionally, the encoders are protected against short circuits and incorrect connections.
