Proximity sensors suit hygiene applications

A SICK (UK) product story
Edited by the Engineeringtalk editorial team Feb 9, 2006

Stainless steel proximity sensors with related connection plugs and distribution boxes suit hygiene applications in food production, bottling and similar plants.

Sick has introduced the Inox series of stainless steel proximity sensors for meat processing, beverage and pharmaceutical applications where high pressure, caustic washdown is the norm.

With a one-piece V4A stainless steel housing (including the sensing face) and an enclosure rating of IP69K, the sensors and the related connection plugs and distribution boxes suit hygiene applications in food production, bottling and similar plants.

Sensing ranges are 10, 20 and 40mm for the M12, M18 and M30 units respectively; these sensing ranges alter very little even when faced with a stainless steel target, which is likely in washdown environments.

High temperatures and washdown at high pressure with acids, alkalis and cleaning agents can get to most items but the Inox range is designed to live in these conditions.

The sensors are suitable for object detection in backup sections and fillers.

The triple sensing range enables a greater detection distance and the protected mounting and fully encapsulated V4A stainless steel housing take care of the rest.

A reduction factor of up to 0.9 for stainless steel improves detection of steel and stainless steel objects.

The M12 connector also complies with IP69K and is available as a connecting cable in lengths from 2 to 5m.

Cables, contact carriers and injection mouldings are in food and beverage compatible PVC and the unions are in V4A stainless steel.

Signals from up to eight sensors can be fed into one distribution box (also with IP69K protection) and the V4A and PVC materials are fully encapsulated to ensure their suitability for food industry hygiene applications.

A common cable for all the sensors leads from the distribution box to the controller.
