The SMA series magnetic switches are rated for 48 Vdc/0.2 A and feature three sets of contacts (NO/NO/NC), with an actuating distance of 7 mm (on) to 20 mm (off). The 0249 switches are designed with an industry-standard M12 connector, while the 0243 devices have a 3-m open-wire cable integral to the unit. Both are sealed to IP67 standards. The switches are housed in 88-mm-long x 25-mm-wide x 14-mm-high plastic modules designed for actuation from front-to-front, front-to-side or side-to-side direction.
