SENC 150 linear encoder
The SENC 150 from ACU-RITE is the ideal scale for all applications. The compact and robust design, and the numerous possibilities for mounting, make it ideal for retrofitting. The slight dimensions and high accuracies of this ball-bearing guided encoder, which uses the reflected light method, are ideal prerequisites that can be used in metrology applications.
- Robust design
- Resolutions from 0.5 µm to 5 µm
- Output signals: TTL
- Measuring lengths from 75 mm/2" to 3075 mm/120"
- Distance-coded reference marks
SENC 150 support
Frequently Asked Questions
What is the difference between the SENC 150 and SENC 50?
The SENC 150 and SENC 50 linear encoders are very similar. The SENC 150 is available in a wider range of measuring lengths, 75mm-3,075mm vs. 25mm-500mm. The SENC 150 also has a slightly more rugged body, with a weight of 0.7 kg/meter of measuring length compared to 0.3 kg/meter.
What applications are the SENC 150 best suited for?
The SENC 150 is a versatile linear encoder that can provide, repeatable, high-accuracy feedback in almost any machining application and environment.
What makes the SENC 150 unique compared to other glass-scale linear encoders?
The SENC 150 linear encoder is a ball-bearing guided encoder designed to be both compact and robust. This versatility, along with flexible mounting options, makes it an ideal choice for retrofitting and/or metrology applications.
