Sensors capture the smallest components
in flight
Contrinex has now upgraded the performance of its high specification range of frame sensors available in sizes from 25mm up to a remarkable 400mm square.
One of the best ways to detect small, free falling components or assemblies from a production process is to use a photoelectric frame sensor Contrinex has now upgraded the performance of its high specification range of frame sensors available in sizes from 25mm up to a remarkable 400mm square

Inductive sensors find position in Hannover
Making its debut on at the Hanover Fair this year is the latest addition to the extremely rugged, yet highly sensitive, Series 700 range of inductive sensors from Contrinex.
To ensure the capture of even the smallest component in flight, the Contrinex frame sensors are designed to detect an object as small as 0.7mm diameter within a 0.1ms response time.
With larger frames the size resolution decreases but even in the largest format, detection of a 5mm diameter item is still possible.
Each frame comprises high performance, through-beam photoelectric sensors mounted in a rugged, compact housing that is environment protected to IP67.
Objects are detected whenever the generated light curtain is broken by anything passing into or through it and a pulse stretching facility ensures that the signal is detected even when components are small and the resulting output duration very short.
The frame sensors can be set in a dynamic or static mode.
The dynamic setting provides an output only when moving parts pass though the frame and is ideal for items such as perforated stampings to prevent them from producing multiple output pulses.
The static option gives an output when any item, whether moving or stationary, interrupts the light curtain, for example, where a product build-up or process interruption occurs.
All Contrinex frame sensors have a voltage range from 10 to 35V DC and are fitted with short circuit protection.
