Short Can Sensors

detects The Can Not The Punch

These high efficiency units detect each can, yet remain totally blind to the punch.

Optimum Tooling & Machine Protection

Using positive discrimination methods and 'zero-drift' detection, these sensors provide reliable detection of short cans or 'tear-offs' to protect your tooling investment.

Maximum Reliability, Minimum Down-time

Sencon Metal Discriminating Sensors employ special encapsulants, sealed cases and custom-fabricated metallic end plates to withstand hydraulic abrasion and provide maximum durability with long service life.

Long Lasting Rugged Construction

Sencon metal discriminating sensors are fully encapsulated in non hygroscopic materials that are 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.

Complete & Compatible

All 2xx Series sensors are equipped with both PNP and NPN outputs, and they are supplied complete with mounting nuts. The sensors optimize production output by significantly cutting bodymaker maintenance requirements.

Special Smart Sensor Systems
for Aluminium Cans

Aluminium canstock is extremely difficult to detect on nickel carbide punches because the electromagnetic signatures are very similar. Sencon’s 387 Smart Sensor is ideal for this situation because it has a built in microprocessor that reads and stores the signal profile of each new punch fitted to the bodymaker. These sensors are used with their own control unit (BCM-387-WR) that interfaces directly with the press control system. The 387 sensor with its dedicated BCM387-WR control module discriminates between aluminium canstock and a range of punch materials, including ceramics and nickel based carbides. The control module is set up for high speed clutch outputs and can be programmed for immediate or timed output. 387 series sensors may also be used in combination with the BCM500 module for more extensive Body Maker control functions (for more information see Body Maker Control Modules).

‡ These sensors perform reliably on the majority of known carbide
punches, provided the magnetic permeability of the punch material
remains stable in working conditions. Factors such as temperature
variation can affect magnetic properties.
