Jan. 27, 2015 – Festo Canada has introduced the new SDAT-MHS series programmable analog feedback position sensors for pairing with any Festo T-slot pneumatic drive.

Describing it as easy to install and program, the SDAT-MHS promises reliable positioning data that assures high repetition accuracy in applications such as pressing, screwing, riveting, ultrasonic welding, and adhesive bonding. The transmitter aims to bridge the gap between simple cylinder switches and costly positional transducers or mechanical potentiometers. Each SDAT-MHS transmitter emits a path-proportional output signal, available with sensing ranges of 50, 80, 100, 125, 160 mm to match strokes of Festo cylinders. This is said to produce accurate feedback across the entire stroke length, including discharge, without the need for the sensors to project beyond the end of the cylinder.

Programming options in both operating modes are: cylinder switch function, window comparator or hysteresis comparator. The IO-Link mode is a universal interface for setting up standard functions without having to program the analog output of a PLC.
