Festo Launches SDAC-MHS C-Slot Programmable Position Transmitter with Integrated IO-Link

Festo has introduced the SDAC-MHS C-slot programmable position transmitter. The sensor combines analog, digital, and IO-Link outputs in a single compact device, reducing the need for multiple sensing components.

The SDAC-MHS is intended for OEMs monitoring the position of pneumatic cylinders and grippers in applications such as product selection, press-fitting, riveting, and ultrasonic welding. By sensing the magnetic piston, it transmits cylinder position to the PLC with a repetition accuracy of 0.2 mm.

Two Sizes Cover Mainstream Stroke Ranges

The SDAC-MHS is available in 20 mm and 30 mm sensing ranges to match common stroke lengths used in Festo grippers and compact cylinders. The sensor detects the full piston stroke and end positions without extending beyond the cylinder body, supporting space-constrained installations. In addition to analog position feedback, the SDAC-MHS includes two programmable digital switching outputs, allowing one sensor to replace two conventional cylinder switches.

Multi-Mode Output and IO-Link

In standard wiring mode, the sensor provides continuous analog position feedback and one programmable digital switching output that can be set as normally open, normally closed, a window comparator, or a hysteresis comparator. With IO-Link, the sensor provides three additional switching outputs and allows all parameters to be configured through a graphical interface.

Key Specifications

For engineers specifying pneumatic position feedback solutions, the SDAC-MHS delivers a three-in-one integration advantage: analog, digital, and IO-Link coexisting in a single package. This reduces the independent sensor count in the BOM while preserving position feedback flexibility. On Festo compact cylinders (ADN series) and grippers, the SDAC-MHS is the factory-matched position detection solution.
