Abstract: A diffuse reflective photoelectric detector head (2) for a solid state limit switch (4) having a photoreceiver with a fixed field of view (FV) and a light source (20) pivotally adjustable to cause its light beam (LB) to intersect the field of view (FV) at varying distances from the detector head, the adjustment being indicated by a mechanical indicator (26f). The head is mountable on a limit switch enclosure (8) in any of four major axis positions, with electrical connections (22a-50a, b, c) for the head being made at the junction of head (2) and enclosure (8).
