Ordering the yg-1a magnetic sensors
To order the yg-1a magnetic sensors, send us a photograph of the existing unit and its nameplate at [email protected]. Please quote the complete code including any revision suffix so that our team can confirm the correct variant, current stock and lead time before you commit.
About the yg-1a magnetic sensors
Elevator and escalator installations are built around a relatively small number of serviceable assemblies, but they fail at very different rates. The yg-1a magnetic sensors 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 yg-1a magnetic sensors 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 yg-1a magnetic sensors 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 Where a superseded revision is the only one available, we say so plainly and explain the substitution, so the installing engineer can make an informed decision rather than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 yg-1a magnetic sensors, 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 yg-1a magnetic sensors 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.
Switches, sensors and wiring degrade gradually and then stop the installation without warning; a device that bolts straight on can still be electrically wrong if the coil voltage or contact arrangement differs.
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.
If the installation is showing an intermittent earth fault that clears as soon as the circuit is disturbed, the identification route is straightforward: the shaft environment is harsher than the machine room, so a component that tests correctly on a dry day can still fail in service.
Inductive loads are hard on switching contacts. A contactor or relay that switches a motor or a coil will pit far faster than one carrying a resistive load of the same rating, which is why the same physical device can last years in one position and months in another.
If you are unsure which variant of the yg-1a magnetic sensors 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.
