Series 61 photoelectric sensors let users benefit from the powerful optical performance without the cost. These UL and cUL listed sensors are available in dc models with a 4-in-1 output and ac/dc models with SPDT relay output. Easy-to-access controls simplify setup and adjustments, and color-coded labels make it easy to identify a given sensor’s sensing mode.

The 4-in-1 output automatically sinks or sources, depending upon the load detected, simplifying setup by delivering four output options from a single sensor. The sensors include standard diffuse mode with a 1 or 4-m sensing range; diffuse with background suppression mode with a 500-mm or 2-m sensing range; polarized retroreflective mode with an 18-m sensing range, and a thru-beam mode with a 60-m sensing range.

The ac/dc versions with SPDT relay output offer switching up to 3 A. For harsh applications, the sensors also come in fiber-optic versions where the sensing range is dependent on the fiber cable. The fiber-optic fitting is suitable for use with all universal glass fiber-optic cables.

Ac/dc connection options include a 2-m fixed cable or a five-pin, M12 ministyle quick-disconnect. Dc connection options include a 2-m fixed cable or a four-pin, M12 micro-style quick-disconnect. The sensors mount via front and rear slots, rear dovetail guide, or M30 × 1.5 mounting base.
