MC 440 with built-in resistance, Alarmtech

MC 440 is a magnetic connector for surface mounting and NC function with 2 pre-mounted resistors of 1K ohm for balanced loop. When installing, select one or both of the resistances to be used, see connection diagram. The connector has a screw terminal with wire cover for easy mounting. With the supplied magnet it works the contact is excellent also on security doors with a very good gap. If you want even greater gaps, the magnet can be replaced by an extra strong magnet, MC 400-MX. Plastic spacers are supplied to the magnetic and contact parts when mounted on steel or to build better distances. The plastic spacers are also available separately, see MC 400-6 and MC 400-7. For thinner plastic spacers, MC 400-3 and MC 400-4 also work. There are also different types of mounting angles, see MC L or MC Z. If different resistance values are desired in the contact, this is good to order.
