Model 1221 – AC limit style
The 1250 is a low cost limit style proximity switch using the same proven detection circuitry as our 1248A. Featuring a 20-250 VAC/DC universal input voltage and a simple two-wire connection. It is available with end, left or right sensing. Other options are a normally open or normally closed output and either an internal terminal block or a factory installed connector.
