Banner Engineering Corp.: Slot sensors
The SL30 and SLE30 Expert™ slot sensors from Banner (Minneapolis, MN) can be used to detect gear teeth, edges, labels, high caps and film register marks.
With emitter and receiver sensors on either side of the U-shaped housing the sensors emit a visible red beam that burns through any airborne contaminants if needed. The fastest model offers 150-microsec. response time with 75-microsec. repeatability. Both models measure 2.88”Lx2.08”Wx0.75”D with a 1.2”Wx2.08”D slot.
