Third Angle Projection Dimensions are shown: mm Specifications and dimensions subject to change E–38 www.ck-components.com MPS Series Magnetic Proximity Sensors Actuating Positions Gap Distance When installing recessed and surface mount contacts, magnet position Gap distance is a combination of the horizontal and vertical plane sepis very important. The switch and magnet must always be parallel or aration of the switch and magnet. Example: if a recessed magnet end to end, and never in a ‘T’ configuration. is 1/4" off the centerline of the switch, the make gap is reduced by 1/4" Correct Configuration Center Alignment Incorrect Configuration Off Center Alignment 1/4, 1 1/4" Make Gap 1" Make Gap E Detect Third Angle Projection Dimensions are shown: mm Specifications and dimensions subject to change E–39 www.ck-components.com
