1000 EXTREME

1000 EXTREME

The steel industry has many examples of environments with extreme requirements in terms of temperature, mechanical forces, vibrations and shocks. For such types of applications, we have designed the 1000 series. An encoder series with exceptional...

2000-series Bearing-less encoders for large shafts

2000-series Bearing-less encoders for large shafts

Some motors require a speed feedback sensor mounted on the main shaft between other parts in the machinery. Here the shaft dimensions may be large – sometimes around a meter – which means that a standard optical encoder is not suitable....

300 MINIATURE

300 MINIATURE

Robust and extremely reliable miniature encoders – that’s the 300 series. These incremental encoders are only 30 millimetres in diameter and intended for installation in applications where space is...

380 Quad Rotary Shaft Encoder

380 Quad Rotary Shaft Encoder

Rotary Shaft Encoders are ideal for use on any rotating shaft to provide a digital output signal to tachometers, counters, speed switches, motor controls, or anything requiring a pulse input. Flexible shaft couplings are available as an option to...

380 Std Rotary Shaft Encoder

380 Std Rotary Shaft Encoder

Rotary Shaft Encoders are ideal for use on any rotating shaft to provide a digital output signal to tachometers, counters, speed switches, motor controls, or anything requiring a pulse input. Flexible shaft couplings are available as an option to...

470 Heavy Duty Encoder

470 Heavy Duty Encoder

Rotary Shaft Encoders are ideal for use on any rotating shaft to provide a digital output signal to tachometers, counters, speed switches, motor controls, or anything requiring a pulse input. Flexible shaft couplings are available as an option to...

500 ROBUST

500 ROBUST

ersatile and modular – these are the encoders in the 500 series. These encoders conform to European industrial standards and are available in a hollow shaft or shaft design, which ensures simple installation. If you are looking for a standard...

700 Compact Hollow Shaft Encoder

700 Compact Hollow Shaft Encoder

The 700 series is compact and robust. The series features large hollow shafts up to 25.4 mm, which means that it can often be mounted directly on the motor's shaft without an intermediate adapter for shaft reduction. This characteristic contributes...
