"MAHALAXMI" make model MLS - 04 / MLS -16 magnetic level switches work on the principle of magnetic repulsion and therefore they are glandless and leak proof instruments. A permanent magnet fitted in the tail piece of the float repels another magnet inside the switch housing which in turn operates an SPDT micro switch. Micro switch contacts can be utilized for initiating audio-visual signals or pump control.

Salient Features :

• As our switches work on magnetic repulsion principle, they are glandless and leak proof.
• No power consumption.
• Internal assembly wiring are teflon insulated.
• Internal switch assembly bracket is of cast aluminium.
• Practically no maintenance is required except periodic cleaning.
• Suitable for 2.5" (65 mm) NB nozzle mounting, (for 63 mm dia float) and 2 " (51 MM) NB nozzle for 48 mm dia float.
• Maximum working temperature 250°C. (Process Temperature)
• Contact ratings of micro switch 5 AMPS at 230 VAC Resistive.
• Also available with micro switch having current rating 10 A at 230 VAC Resistive.
• No of contacts : 1 change over as standard. Optional - 2 change over
• For high temperature upto 350°C (Process temperature)
• 1 number SPDT Reed switch with current rating 100 VA, max. switching current 5 Amps, max, switching voltage 230 VAC / 200 VDC
• Specific Gravity : Down to 0.75

Note : Flanged connections as per ASA/BS/DIN or JIS available on request, as per customer requirement.
 
Caution :

• Level Switches should not be used for direct starting / stopping of pumps. An external relay or contractor must always be used with the level switch.
• MLS-04/MLS-16 side mounted level switches must always be mounted horizontally with outgoing cable entry facing downwards.
• In case of high temperature model MLS-04-92 HT/MLS-16-92HT and low temperature models SMT-04-F82 and SMT-04-F92 arc suppressors/current limiting bias resistor must be provided depending on the load viz inductive or lamp load etc. to reduce the deteriorating effect of contacts due to surge voltages and high in-rush current.
