Abstract
The specification discloses a magnetic proximity sensing apparatus especially adapted for use with fluid cylinders having pistons formed from magnetically attractable material. The apparatus includes clamping means for securing it to a tie rod of a fluid cylinder or directly to the cylinder body in juxtaposition to a side of the cylinder without disassembly of the cylinder. Also included are magnetic actuator means responsive to the proximity of the fluid cylinder piston which close a switch and enable electrical circuitry for controlling fluid valves or other apparatus.
