Omron D5A-8511 Limit Switch
Omron D5A-8511 is a top-plunger limit switch with a maximum repeat accuracy of 3 µm and operating force of 3.92 N maximum. A 3 m prewired cable is supplied, while IP67 protection is specified for the switch. The combination of top-plunger actuation, micron-level repeatability, and 3 m cable length defines this particular configuration within the D5A range. The D5A-8511 belongs to the D5A Series within the precision top plunger switch range from Omron control components. Cable length is the clearest difference from the related 5 m versions.

The Omron D5A-8511 Limit Switch uses a top-plunger actuator and is supplied as a prewired model with a 3 m cable. Maximum repeat accuracy is specified at 3 µm, while the maximum operating force is 3.92 N. IP67 protection is also listed. Unlike the D5A-2100 and D5A-2200 rows, the source does not provide contact form, current rating, operating temperature, mechanical life, or electrical life for this model, so those specifications are intentionally omitted. Its identification rests mainly on actuator type, repeatability, operating force, connection style, and cable length.
The 3 m prewired lead is the most straightforward point to compare with other D5A-851x versions. D5A-8512 retains the same stated top-plunger format, 3 µm maximum repeat accuracy, 3.92 N maximum operating force, and IP67 protection but extends the prewired cable length to 5 m. This makes cable reach a useful selection factor where the core mechanical specification is otherwise similar. For the longer prewired version, see the D5A-8512 model.
