Stainless Steel Sensing Face Proximity Sensor FL7SSeries The FL7S is a proximity sensor having a stainless steel sensing face and housing, and is specially designed for welding applications on the automobile manufacturing line. The sensing face is integrated into a stainless steel housing having high shock resistance and superior abrasion resistance Sensors have a spatter and slag proof special coating An electromagnetic field noise elimination is built in The lineup includes M8, M, M8 and M0 models Connector-type cables are also available for the FL7S Series. PA5-ISX FK-E (incombustible cable) Ex.: PA5-ISX UK-E (flame-resistant cable) ADVANTAGES OF FL7S SENSORS 0.7mm The sensing face is integrated into a single stainless steel housing. Special spatter-resistant coating Highly resistant toelectromagnetic field noise from welding! Extra-tough filling material FL7S SERIES ENDURANCE TEST RESUCTS Two endurance tests were made in order to develop a sensor that could meet the severe requirements demanded by users in the field. The FL7S Series has proven to have superior performance in both tests. strength tests TEST- Stationary The Metal Brush Test (measurement of abrasion resistance) With conventional sensors, welding sparking leads to hard-to-remove spatter and slag.the big problem is the scratches caused by the abrasive metal brush used to remove the stuck spatter and slag. Yamatake has solved this major problem by creating for the FL7S Series a stainless steel sensing face that resists abrasion. The Metal Brush FL7M-7J6HD FL7M-7J6HW FL7S-5W6W-CN0 Rotating Test condition Brush: Stainless steel brush Rotation speed: 0 cycles/min Survives 5 min of brushing Survives 5 min of brushing Still working well! Operation is normal even after 00 minutes! TEST- Repetitive Shock Test (measurement of shock resistance) Stationary Rotating Repetitive shocks when welding parts hit the sensor head result in a shortening of sensor life. The FL7S Series' greatly strengthened stainless steel sensing face is the answer to this problem! The repetitive shock test has proven that this sensor has robust shock resistance.
