ELAP Absolute Linear Transducers with IO-Link Interface

The absolute linear transducers series PNS ILK and PN2S ILK with IO-Link interface represent an advanced solution for position measurement in industrial automation.

Key features and benefits:

• PNS and PN2S ILK integrate the transducer measurement function with the features offered by IO-Link protocol: communication, interoperability, ease of installation.

Absolute linear transducers are used on industrial machines to measure and control the linear displacement of axes; as absolute detection systems, they maintain the true position even without power. This makes them particularly suitable for machine applications where re-zeroing the axis after every power cycle is complicated, for example, if the material remains in process for a long time.

IO-Link Technology for Industry 4.0:

• Thanks to IO-Link technology, the new transducers, besides detecting the position, transmit a series of cyclic (process) and acyclic data (parameters, error messages, warnings, notifications) in real time; this allows for optimal, even remote, production management (as in IIoT systems).
• The IO-Link master is compatible with most industrial fieldbuses, thus facilitating integration into existing systems.
• Data transmission, based on a 24V signal, is clean and secure, immune to interference.

Smart Sensors Functionality:

Like all smart sensors, PNS and PN2S allow for the setting of operational parameters, such as maximum position, increment direction, and alarm thresholds for temperature or position. They also support a diagnostic function for system monitoring, which facilitates predictive machine maintenance. The resolution is 12 bits (4096 steps). The resistive element made of conductive plastic ensures precision, repeatability and a long life.

Options and Fittings:

The transducers are available in two versions:

• PN2S ILK, equipped with two ball joints at the ends, with strokes ranging from 50 to 500 mm, and
• PNS ILK, with strokes from 50 to 950 mm, and. The PNS transducers may optionally mount a ball joint or a mis-alignment joint, or a feeler pin, and the external return spring (up to 150 mm stroke).

Both types are cased in a sturdy aluminum housing ensuring excellent resistance to shock, vibration and environmental agents. Connections are provided by the 4-pin M12 connector, as per IO-Link standard.

Installation and Configuration:

The transducers simple installation and commissioning is an added advantage:

• Mechanical fixing occurs by means of metal supports along the transducer body.
• As with all IO-Link systems, the wiring is reduced, as the signal and power supply pass through a single, unshielded cable, with a maximum length of 20 metres.
• Devices can be easily configured using the Port Configuration Tool: the software recognises the devices connected to the Master, and automatically downloads the descriptor files (IODDs).
• Furthermore, IO-Link features the self-parameterization, a function of the Master that saves all the parameters of the connected devices: in case of transducer replacement, the Master automatically reconfigures the device, making maintenance operations easier.
