Igus lightweight lead screws from Treotham Automation

The new dryspin lead screws from igus can reduce weight by up to 60 per cent when compared to stainless steel options.

According to the company, the tribologically optimized plastic lead screw nuts and hard anodised aluminium screws significantly increase the service life and reduce the amount of maintenance and external lubrication required.

They are a great alternative to stainless steel options. Aluminium is not only very light weight, but  the asymmetric geometry also reduces friction, wear rates and vibration.

The wide range of igus lead screw nuts are made from the self lubricating iglidur material, and are available in anti-backlash and different thread options. All the lead screw sizes that were previously only available in stainless steel are now available in lightweight, rugged anodised aluminium. The lead screws are available in diameters from 6mm to 20mm.

Dryspin lead screws are typically used in closing units, automotive and handling. When lubricants are eliminated they are suitable for clean environments such as laboratory automation and medical devices.

New sensors for roller conveyor systems

The new Wenglor reflex sensors with background suppression for roller conveyor systems are high performance sensors that are quick and easy to mount. 

The new reflex sensors can be used to control and detect objects on roller conveyor systems. They are suitable for warehouse and logistics centres and can reliably detect small packages with widths as small as 150mm, with conveyor widths of up to 900mm. Dark objects can also be reliably detected due to the precision of background suppression.

The sensors offer a fast-clip mounting system that reduces installation and maintenance time and cost by up to 60 per cent compared to conventional screw type mounting systems. With just a single click to mount, they offer a secure, stable mounting system with a long service life.

The quick wiring feature allows the wiring effort to be reduced by 90 per cent, with the M12 plug turning just 180° to securely connect to the sensor. The cables are also compatible with all standard cables.

Switching distances can be detected and adjusted extremely quick and easily due to the new 270° scaled potentiometer, even when the sensor is not operating.

Thanks to the eco mode, the current consumption is reduced by 75 per cent for the solenoid valve and even more in the switched state, to less than 16mA. It can be used in temperatures from -40°C to 60°C.
