TRM can supply optical incremental encoders of various Pulses Per Revolution (PPR) and output type. Typical applications include positioning tables, CNC machines, robotics, assembly machines motor mounted feedback, packaging machines, and general motion control applications.
Generally TRM will mount encoders directly on the rear of a DC servomotor as this provides excellent security, stability and precision. All too often we see encoders mounted on machines that are driven by chains or belts and this inherently leads to inaccuracy in the system and instability of the motor. For a system to be "under control" we need to see 2 pulses from the encoder and this will indicate which direction the motor is turning. In most applications a Z pulse is not required however where high precision is required a Z reference pulse can be used either on a rotary encoder or linear scale.
Screening of the encoder signals is highly important and we ensure all the encoders we supply have a good quality braided screen to ensure a good clean signal is received into the control system.

Features of a typical encoder:
- Thru Bore
- 6 mm bore size
- PPR - as per order
- Square wave output
- Line Driver
- 5 Vdc operating voltage
- 0 to 70 oC
- IP 50
TRM can also supply encoders as Jog encoders with various handwheels for CNC and similar applications. We can supply with different cable lengths, connectors to suit the application or we can supply ready mounted inan enclosure or to a DC motor ready to mount on a machine.
