A1S30 Optoelectronic Sensor


Sensor A1S30, suitable for most applications

The BRAUN Optoelectronic Sensor Series A1S30P is designed for various applications with smooth or profiled targets: a dot of paint on a shaft is adequate to start measurements. Likewise, a fan blade, a screw head, a slot, or a cam will serve. Our high reflecting adhesive tape U1A006 helps with difficult applications. The Function does not depend on the target material. Therefore, no load influence on the object.

The sensing distance is widely dependent on the contrast and reflection grade of the target. Recommended 1-2 cm for the A1S30P. It is not affected by the luminescent light ambiance.
