Series 61 Photoelectric Sensors enable machine builders to benefit from the powerful optical performance without the cost traditionally associated with high optical power. These UL and cUL listed sensors are available in DC models with 4-in-1ô output and AC/DC models with SPDT relay output, for an all-in-one solution that satisfies any number of application needs. Accessible controls simplify set-up and adjustments, and color-coded labels make it easy to identify a given sensorís sensing mode. AC/DC versions with SPDT relay output are capable of switching up to 3 Amps. For harsh applications, the sensors are also available in fiber optic versions where the sensing range is dependent on the fiber cable. The fiber optic fitting is suitable for use with all ìuniversalî glass fiber optic cables.
