250VDC	0.4		0.1	0.1	0.4		0.1

Note:

Power factor of inductive load is above 0.4 (AC). The time constant is below 7ms (DC).
The inrush current of lamp load is 10 times that of steady state current, and the inrush current of motor load is 6 times that of steady state current.

Operating Characteristics

OF (Max.)	2720g	2720g
RF (Min.)	910g	910g

MD (Max.)	1mm	1mm
OP	44±0.8mm	44±0.8mm

Dimension (unit: mm)

Note: In the diagram, OP means operation position, at which the external force is applied to the drive lever to make the movable contact just operating from the state of the free position. PT means pretravel, the distance the drive rod moves from the free position to the operation position.

Tips: Testing before installing limit switch

When actually using the limit switch, unexpected problems may occur. Therefore, testing before installation should be done to the extent possible.
In the test, not only the load conditions but also the use environment must be tested under the same conditions as the actual use state.
Each rated performance value described in the catalog is the value under the following conditions unless otherwise specified.

Inductive load: power factor above 0.4 (AC).
Time constant 7ms or less (DC).
Solenoid: Inrush current is 10~20 times of constant current.
Lamp load: Inrush current is 10~15 times of constant current.
Motor load: Inrush current is 5~10 times of constant current.
Relay: Inrush current is 4~5 times of constant current.

The use environment:

Ambient temperature: -10~+350℃
Ambient humidity: 40~ 70%RH

Note that inductive loads are particularly problematic in DC circuits, so it is necessary to fully understand the value of the load's time constant (L/R).

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
