Magnetic Linear Encoder Solves Issues with Variable Gap Distance
The new BML SF2 system from Balluff provides 12 micrometer system accuracy at gap distances up to 1.0 mm and a maximum working gap distance of 1.8 mm. The accuracy greatly simplifies installation, start-up, and operation. The BML SF2 system is the ideal linear position feedback solution for demanding applications such as cutting and forming machinery, X-Y positioning, and direct feedback on electric drives.
According to Balluff Product Marketing Manager for Measurement Sensing Products Scott Rosenberger, this new incremental magnetic encoder solves problems associated with the sometimes hard to achieve mechanical tolerances required when installing magnetic encoder systems.
"Even with careful mechanical design, it's sometimes difficult to keep the magnetic sensor head in proper alignment with the magnetic tape. This new product solves those problems by providing trouble-free operation at easily-achievable sensor-to-tape gap distances," Rosenberger added.
The BML SF2 incremental encoder system is available with industry-standard A/B/Z quadrature or analog sine/cosine interfaces and is available in operating lengths of up to 48 meters. The flexible, magnetic tape can be ordered in bulk and cut to length per application requirements.
Additional features of the BML SF2 linear encoder system include:
- Compact, metal sensor housing to allow installation in tight spaces
- Integrated status LED on sensor head to provide at-a-glance indication of status during installation, start-up, and normal operation
- Non-contact action for wear-free operation and long service life
