PCS 100


It changed an industry

There are many reasons why the PCS 100 has become the number one sensor choice at so many facilities in North America and now, worldwide. We kept it simple, it works, it’s tough and it’s affordable. The PCS 100 is mechanically adjustable, which allows you to easily set or change the sensing needle sweep from 0° – 180° in either CW or CCW direction. We’ve also eliminated the need to use a miniature reversing gear box, subject to constant wear and tear. With a capability of over 200 cycles per minute, the PCS 100 will keep pace with your fastest machine.

Settings and Diagnostics

After mounting, setting the PCS 100 sensor is simple. Set the desired swing angle and swing direction for your application using the patented adjustment feature on the sensor head. Make sure the tool or object to be checked is located between the start and stop position of the swing angle selected. Now flick the selector switch on the control box to correspond with the CW or CCW swing direction selected. If the sensing needle is allowed to travel to its stop indicating a broken tool (or missing object), a fault output is generated through the PCS control box to the machining cycle stop or feed hold. System faults will also occur if you have incorrectly set swing direction or if electronic failures occur between the sensor and the control box such as in the case of a cable disconnect or problem. The PCS 100 diagnostic system is designed not to fault if the sensing needle is held back from contacting the tool or object being monitored. It will only fault when the tool breaks or object is missing. This can avoid expensive nuisance faults in many applications. One such application example includes a chip nest condition that builds around the tool and you don’t want the machine to stop until both the chip nest and tool actually break away. The PCS 100 design is also great for CNC lathes or machining centers because it ignores common and significant tool to tool diameter differences. If you prefer a fault output when any deviation from the normal sensor swing occurs, select the PCS 250 teach system.
