Updated EtherNet/IP functionality maximises effectiveness of magnetostrictive sensors

Written by: Tom Austin-Morgan | Published:

MTS Sensors has enhanced its R-Series of high performance magnetostrictive sensors. The series now conforms to the latest version of the EtherNet/IP communication protocol with device-level ring (DLR) compatibility, having also recertified against the ODVA EtherNet/IP Composite Conformance Test revision CT12. Through this, interfacing with a wider array of EtherNet/IP compliant hardware across numerous industry sectors has been made possible - such as factory automation systems, plastic injection moulding apparatus and materials handling equipment.

These enhanced R-Series sensors are claimed to be better equipped for industrial networking implementations than before. Their DLR capability permits direct connection to a ring topology without external switches needing to be employed.Via the DLR device-level network re-routing and failure point identification engineers can benefit from improved reliability and shorter network recovery periods.

The R-Series is offered in a choice of rod style, profile style and flex style configurations, with stroke lengths of 25 to 7620mm, 5 to 5080mm and 255 to 10,060mm respectively. The rod style units are optimised for implementation in hydraulic cylinders, while the profile style units facilitate machine mounting and the flex style units are a flexible sensor offering which provides trouble-free performance in applications requiring very long stroke lengths and linear measurements on an arc.

Based on MTS’ Temposonics magnetostrictive sensing technology, these sensors are all claimed maintain repeatability to within a margin of ±0.001%. The rod and profile style units are said to support 1µm resolution levels and their linearity deviation is also said to be less than ±0.01%. The flex style unit specifications are claimed to have 2µm resolution and ±0.02% linearity deviation.
