IFM Electronic has released safety light curtains that feature 14mm resolution, fine enough to detect a finger. Designed for areas of machine access where an operator's fingers could become trapped, the latest additions to the OY range of light curtains meet Type 4 to IEC 61496, SIL3 to IEC 61508 and PLe to ISO 13849. Ten versions of the 14mm resolution types make up this additional selection, with protected area heights ranging from 160 up to 1510mm in 150mm increments.Each of the 10 types will protect an area up to 6m wide and combinations are possible to cover areas on adjoining planes. The OY series light curtains and grids are available as Type 2 or Type 4 to IEC 61496 in heights from 160 to 1510mm covering distances up to 20m with resolutions from 14 to 90mm. On all products the beams are incorporated right up to the end of the 28 x 30mm housing, allowing installation without deadband.
