Choice of 25, 30, 35 or 40lbs holding force determined by units specified voltage. Reduced power supply requirements and energy costs due to low power consumption (15mA to 40mA). Field selectable high holding force comes standard, reducing stock or need to special order high holding force. Screw terminal block input connections for simple and neat wiring. Innovative installation eliminates the need for secondary alignment adjustments. Ball pivot assembly enables full plate contact and holding force. Optional adjustable rod compensates for extreme misalignment up to four inches. Slotted mounting holes enable adjustment of magnet centerline.
