Metal discrimination sensors designed specifically for short can detection in the demanding bodymaker tooling environment. These high efficiency sensors detect the can, yet remain totally blind to the punch. The sensors employ special encapsulants, sealed cases and custom-fabricated metallic end plates to withstand hydraulic abrasion and provide maximum durability with long service life.
PLEASE NOTE: The 11R-387SCT-M12DC is a 387SCT sensor with a short built-in cable terminated with a micro M12DC (5pin single key) plug. This allows the connector to be placed outside the bodymaker’s wet area. It also offers the dual benefits of an encapsulated cable on the sensor itself plus a quick-disconnect connector.*The -63 sensors are obsolete and can be directly replaced with the -03 which has the same specification. Alternatively you can upgrade to the 487 series short can sensors.**These models are also available with an output pulse stretcher (See Can-on-Mandrel and High Performance Sensors). All 11 series sensors are not supplied with a cable.
Other cable lengths and connector styles are available, please contact your local Sencon sales office for details.

Sencon Metal Discriminating Sensors are fully encapsulated in non-hygroscopic materials and are designed to be highly resistant to shock, vibration, coolant oils and humidity. They also employ custom-fabricated titanium sensing face protection plates to withstand hydraulic abrasion and provide maximum durability in the demanding bodymaker tool environment. With no need for adjustment or monitoring, Sencon Short Can Sensors keep machine downtime and maintenance needs to a minimum and so help to promote optimum productivity.
Sencon has extensively tested and evaluated carbide wall-ironing punches. These punches use various binder materials—most commonly nickel and cobalt, as well as other elements such as chromium and iron — to obtain the desired mechanical properties for the punch. The mixtures and compositions of these materials impart differing magnetic properties to the finished punch tooling.
An increasingly diverse range of punch types is now available, and material compositions often display subtle variations which may affect short can detection capability. The 487 short can sensor can be optimized to a specific punch via a simple push button or PC interface.
487 series sensors can be optimized to a specific punch in the bodymaker via push button or client software, this optimizes the sensor to the specific punch’s magnetic properties and mounting distance. Instead of having a specific sensor which is calibrated during manufacture to a generic target material, the 487 can be optimized to the unique set of circumstances for each bodymaker.
The optional client software allows easy set-up and fault diagnosis. The interface displays punch signal information which enables ease of installation, running confidence, and fault diagnosis.
The 487 can be field updated with “Punch Discrimination Packs” (PDPs); software packs that enable the sensor to work with different punch materials. This offers canmakers the opportunity to buy once and remain flexible to tooling changes in the future.
These sensors are used with the SCM387 Control Module which communicates with the press control system to discriminate between aluminum can stock and a range of punch materials, including ceramics and nickel based carbides.
Aluminum can stock is extremely difficult to detect on nickel carbide punches because the electromagnetic signatures are very similar. The 387SCT 'smart' sensor is ideal for this situation because it has a built in microprocessor that learns the signal profile of each new punch fitted to the bodymaker.
These high efficiency Short Can Sensors detect each can, yet remain totally blind to the punch. Using positive discrimination methods and 'zero-drift' detection, these sensors provide reliable detection of short cans or 'tear-offs' to protect your tooling investment. All 200 Series short can sensors are equipped with both source (PNP) and sink (NPN) outputs, and they are supplied complete with mounting nuts. The sensors optimize production output by significantly cutting bodymaker maintenance requirements.
The 287 series short can senors perform reliably on the majority of carbide punches, provided the magnetic permeability of the punch material remains stable in working conditions (factors such as temperature variation can affect magnetic properties). Combinations of can stock, light weighting and the latest generation of punch materials may cause detection issues, in which case Sencon recommends upgrading to the latest 487 series short can sensors.
