Hall Effect Switches Suit Rugged and Harsh Environments

APEM has introduced two Hall effect switches, designed to work in rugged and harsh environments. The new IH Series of switches are low maintenance, contact less, sealed pushbuttons that come in two versions: linear proportional output, and momentary switch. The switches are made of durable materials, including switch bushings of Zamak, a robust family of alloys with a base metal of zinc and alloying elements of aluminum, magnesium and copper. Life expectancy for both versions is estimated at above 5 million cycles at least ten times more than the classic mechanical switch, which is rated for about 500,000 cycles. With low behind-panel depth and IP67 sealing guaranteeing protection against the effects of being immersed in water 15 cm and up to1 m deep for 30 minutes, the IH Series is appropriate for customers looking to reduce maintenance, especially in remote military or outdoor locations where switch replacement may be difficult. Those integrating switches into dashboards or panels with space issues will find the compact size and low profile critical factors.
