For a classic start/stop pair, the 1554MPB2 provides two 22.5 mm push button positions in a slim polycarbonate housing. It fits OEM and field applications where a sealed two-device station has to survive rain, hose-down or dusty conditions. The 30.5 mm hole equivalent is the 1554PB2.
The light gray (RAL 7035) polycarbonate carries a UL94 5VA rating and is suitable for outdoor use. The lid is secured with self-captivating M4 stainless steel machine screws in integral stainless steel bushings over a replaceable, preformed high temperature silicone gasket. The base includes internal DIN rail mounting tabs, and the series provides threaded M3 brass inserts and standoffs for M3.5 or #6 self tapping screws plus molded card guides for 1.5 mm PC boards in all but the smallest size.
The 1554MPB2 ships with box, lid, 4 cover screws and gasket; recommended cover screw torque is 43-57 ozf-in (30-40 cN-m). A 1554JPL galvanized steel inner panel (5.80 x 3.00 in) and 1554FT mounting feet are optional. Ratings are IP66 and NEMA 4, 4X, 6, 6P, 12 and 13, with cUL US Listing (file E65324) and UL 508A approval shown on the drawing. RoHS and REACH compliant.
