Multi-turn absolute encoders ready for Factory 4.0

By Heather Hamilton, contributing writer

Sensata Technologies announced the availability of the MHM5 and MHK5 absolute multi-turn encoders with either Ethernet/IP or ProfiNet interfaces for Factory 4.0 applications. They are available in shafted (MHM5) and blind-shaft (MHK5) configurations for greater design flexibility. These devices are designed to withstand shock and vibration and are sealed against harsh environments.

The MH encoders provide up to 16 bits per turn and 14 bits of turns counting and come in compact packaging, which provides for easy integration into existing designs. An operating temperature range of −40°C to 85°C and an IP65 rating make them suited for a variety of industrial applications.

The encoder design includes a geared turns counter that is immune to electrical and magnetic interference, said Sensata. Standard features include reverse polarity and short-circuit protection.

Enabling the collection of data required for industrial and factory applications, the bus-compatible multi-turn encoders are used in packaging applications to identify product position in a process line, signaling when action should be taken, said Sensata. Another common application, said the company, is metal forming such as determining the absolute position of strips, bars, rolls, or tubes in a process that may need to be marked, scored, slit, inspected, or formed.

The encoders may also be used to determine the rotation angle and position of a crane boom and cable payout amount, as well as in heavy vehicles for proper placement in applications such as off-road mobile platforms and construction and mining equipment.
