Position and speed detection for electric drives
Balluff offers a broad array of simple on/off presence detection sensors in a wide variety of form factors and sensing principles.
In highly dynamic applications where each gram of weight savings means an improvement in acceleration rates and energy efficiency, Balluff's expertise in micro-optical, mini-inductive, and mini-magnetic sensors offer flexible alternatives to machine designers.
The extended temperature range of the inductive BES standard sensors ensures operation free of interference: They measure shaft speeds in the plant construction at temperatures down to –40 °C. Two sensors are sufficient for measuring the speed, detecting the direction of rotation and reliably protecting the equipment from overspeed.
BML S1F magnetic encoders precisely and reliably measure the speeds of the drive shaft directly on the motor. Their narrow form factor allows the existing motor design to remain compact.
Our BML magnetic encoders detect both the direction of rotation and the correct shaft position using reference points. They are extremely accurate at all rotational speeds.
Thanks to their compact design, Balluff's high-performance inductive micro-sensors can also be integrated into places where standard inductive sensors won't fit. Inductive micro-sensors can be used for end-of-travel limit switches and for detecting index positions on linear and rotary drive mechanisms.
Inductive mini-sensors are ideally suited for end position detection in spindle drives. Their flat, rectangular form factor fits easily into most designs.
