Multiturn encoder assures compatibility

This multiturn absolute encoder is believed by CTL Components to be the first to feature a 2in diameter hollow shaft. Manufactured by IVO, the G2P1H programmable encoder is designed to be compatible with industry standard servo motor shafts, making it suitable for use in a wide variety of motion control applications.

The encoder is equipped with a parallel interface and offers a resolution of 24bits, equivalent to 4096 revolutions with 4096 angular steps per revolution. Output code can be selected from Gray, clamped Gray, binary or BCD formats. These parameters, together with rotation sense, are all easily programmed on a PC using IVO’s ProGeber Windows-based software.

The G2P1H encoder carries out a self test routine upon installation, and automatically monitors a number of key functions during operation. It has a supply voltage range of 10 to 30V DC, a maximum current compensation of 50mA at 24V DC, and a code switching speed of 400kHz.

Featuring an aluminium housing and IP54 environmental protection, the encoder complies with the relevant European standards for electromagnetic compatibility and can be used in ambient temperatures ranging from –20 to +80°C. It measures 116mm (outside diameter) by 71mm, and weighs 1.2kg.
