Stainless Steel Sensing Face Proximity Switch Model FL7S The FL7S is a proximity switch 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 Switches have a spatter and slag proof special coating An electromagnetic field noise elimination is built in The lineup includes M8, M2, M8 and M0 models * Connector-type cables are also available for the FL7S Series. PA5-ISXm FK-E (incombustible cable) Ex.: PA5-ISXm UK-E (flame-resistant cable) ADVANTAGES OF FL7S SWITCHES The sensing face is integrated into a single stainless steel housing. 0.7 mm 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 switch 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- With conventional switches, 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. Azbil has solved this major problem by creating for the FL7S Series a stainless steel sensing face that resists abrasion. The Metal Brush Test shows that this switch has excellent endurance. Stationary The Metal Brush Test (measurement of abrasion resistance) FL7M-7J6HD FL7M-7J6HW FL7S-5W6W-CN0 Rotating Test condition Brush: Stainless steel brush Rotation speed: 0 cycles/min TEST-2 Survives 5 min of brushing Stationary Rotating Repetitive Shock Test (measurement of shock resistance) Housing survives 0 repetitions Resistance to electromagnetic field noise from welding!

Repetitive shocks when welding parts hit the switch head result in a shortening of switch life. The FL7S Series' greatly strengthened stainless steel sensing face is the answer to this problem! The repetitive shock test has proven that this switch has robust shock resistance.
