The 27969PSLA is a narrow Eddystone die-cast enclosure measuring 91 mm x 38 mm x 31 mm (3.6 in x 1.5 in x 1.22 in). Its long, thin shape takes a P.C. board up to 78.61 mm x 28.12 mm, a good match for strip-style circuits, cable-end electronics and small sensor conditioners.

Box and lid are die-cast from aluminium alloy to BS1490, LM2M, supplied in a natural finish. The material is tough yet easy to machine, so cut-outs and holes can be added to suit the design. A lap joint between lid and box provides protection against dust and splashing water, and the enclosure is rated IP54.

The ordering table lists 3.62 in (92 mm) length, 1.50 in (38 mm) width, 1.22 in (31 mm) total depth and a 0.16 in (4 mm) lid. The drawing dimensions it at 92.40 mm [3.64 in] x 38.30 mm [1.51 in] x 30.60 mm [1.20 in]. Shipping weight is 0.18 lbs (0.08 kg), packed in shrink wrap.
