Omron D4C-3260 Limit Switch
Omron D4C-3260 uses an R38 center roller lever with a 17.5 mm × 7 mm sintered stainless steel roller, giving this model a lever-based actuation format instead of a plunger. It supports 4 A at 30 VDC and comes with a 3 m four-core VCTF oil-resistant cable. The specified IP67 protection, 300 mΩ maximum contact resistance, and long mechanical life make the electrical and mechanical configuration easy to compare with other D4C variants. The D4C-3260 is part of the D4C Series under the center roller lever limit switch range from Omron limit switch products.

The Omron D4C-3260 Limit Switch is built around a center roller lever with an R38 operating radius and a 17.5 mm × 7 mm sintered stainless steel roller. Rather than using a direct plunger, this configuration transfers target movement through the lever before operating the SPDT contact. The switch carries a 4 A at 30 VDC rating and is supplied with a four-core, 3 m VCTF oil-resistant cable. The cable uses a nominal conductor section of 0.75 mm² and has a diameter of 7.6 mm. IP67 protection is specified, along with an operating range of -10 to 70°C and relative humidity from 35 to 95%.
The supplied specifications list 10 million mechanical operations minimum and a maximum contact resistance of 300 mΩ. Shock ratings are 1,000 m/s² maximum for destruction and 500 m/s² maximum for malfunction. For model selection, the important combination is the center roller lever, 30 VDC current rating, and 3 m cable length. This makes it easy to separate the D4C-3260 from similar D4C units that differ mainly in actuator geometry or cable reach. The closest cable-length comparison is the D4C-3360, which keeps the center roller lever format but uses a 5 m cable.
