Magnetic Level Switch (MLS) level switches provide low-cost, reliable alarm and control functions to meet your requirements.
MLS switches are non-invasive alarm switches which clamp to the side of the chamber and are magnetically actuated by the float through the chamber wall. Multiple control points can be added to the Level Indicator without having to cut additional holes in the vessel. External mounting clamps allow for easy adjustment of set points or servicing of MLS switches without interrupting the process.
Wiring can be either rising or falling level and NC or NO operation. Each switch has approximately a 1/2 inch dead band to eliminate the possibility of chatter.

Description
MLS-3 Series
The MLS-3EX is a hermetically sealed reed switch with Form C contacts. A bias magnet latches the switch, maintaining the output contact as the float continues to rise or fall within the gauge. The switch will only unlatch when the float passes the switch again in the opposite direction. This low-cost switch is best suited for low power alarm signals.
MLS-10EX
The MLS-10EX is a high current level switch and is an excellent choice for controlling pumps, alarms or solenoids. The switching mechanism is a cam activated internal UL approved switch. The unit can be set by the user for rising or falling activation. The MLS-10EX-C is a DPDT switch. These switches meet Class 1, Div. 1 requirements and the internal micro-switches are UL approved. The MLS-10EX-R (relay requires auxiliary power) is available for higher inductive load.
