The SME120/SME125 Sensor Modules External are encoder evaluation units with degree of protection IP67, especially suitable for use in linear and torque motor applications. They can be installed close to the motor systems and encoders in the machine.

Sensor Modules External evaluate the encoder signals and motor temperature sensors specifically and convert the information obtained for DRIVE?CLiQ. The motor temperature signals are safely electrically separated.

A Hall-effect sensor box can be connected for the SME120 to determine the commutation position of a linear motor.

Neither motor nor encoder data are saved in the SME120/SME125.

The SME120 and SME125 can be operated on Control Units with firmware release V2.4 and later.

The following encoder signals can be evaluated depending on the type of Sensor Module:

• Incremental encoder sin/cos 1 V_pp
• Absolute encoder EnDat 2.1
• SSI absolute encoder ¹⁾ with sin/cos 1 V_pp incremental signals, but without reference signal

The motor temperature can also be detected using KTY84?130 and PTC thermistors.

¹⁾ For SME125, only SSI encoders with 5 V supply voltage.
