Ordering the magnetic proximity switch

To order the magnetic proximity switch, send the exact model or reference code printed on the original part to [email protected]. Please quote the full code including any suffix so that our team can confirm the correct variant, current stock and lead time before you commit.

About the magnetic proximity switch

Elevator and escalator installations are built around a relatively small number of serviceable assemblies, but they fail at very different rates. The magnetic proximity switch sits in the switches / sensors / wiring group, and it is replaced on a different service interval from the assemblies around it. In practice the failures we see on magnetic proximity switch come down to contact pitting, moisture ingress at the cable gland, drifted optical alignment, and brittle insulation on travelling cables after years of flexing.

Every magnetic proximity switch we supply is inspected before dispatch. Each unit is checked for physical damage, correct marking and the specific wear or degradation patterns that matter for this class of component, then packed to survive international transit. Where a superseded revision is the only one available, we say so plainly and explain the substitution, so the installing engineer can make an informed decision rather than discovering the difference on site.

Buying guidance and compatibility notes

Before ordering the magnetic proximity switch, confirm three things. First, the switch or sensor model, the mounting pattern, and the supply voltage and contact configuration (NO or NC). Second, contact configuration matters more than physical size — a switch that bolts straight on can still be electrically wrong. Third, whether the installation is a traction lift or an escalator, since duty cycle and loading differ between the two.

On fitting, one point is worth repeating: record the terminal numbers before disconnecting a travelling cable, since colour codes are not consistent between controller generations. Almost every repeat failure we see on magnetic proximity switch traces back to a related component that was left in place, or to an adjustment that was assumed rather than measured.

Levelling and position sensing are unforgiving of drift. A sensor that has moved by a millimetre, or a vane that has been nudged during maintenance, can produce a fault that appears intermittently and is difficult to reproduce on a service visit.

Sensing and switching devices decide whether the controller can trust what it is told, which is why common switches, sensors and relay types are held as stock, because the failure is invisible until it happens.

Displays, buttons and intercoms are passenger-facing, so their failure is immediately visible and often reported before any technical diagnosis is possible. Keeping common faceplates and modules in stock shortens the outage considerably.

Switches, sensors and wiring degrade gradually and then stop the installation without warning, and the symptom that most often brings an engineer to it is a floor position that reads incorrectly at one landing only.

If you are unsure which variant of the magnetic proximity switch you need, send a photograph of the nameplate and the existing component alongside a description of the fault. That is usually enough for our team to identify the correct replacement without a site visit, and it avoids the cost and delay of returning an incompatible part. We are also happy to advise on the other serviceable items in the same switches / sensors / wiring group, so a planned shutdown can cover several wear items at once.
