Omron D4F-102-1R Limit Switch
Omron D4F-102-1R is a slow-action limit switch with a metal roller-plunger actuator and 1NC/1NO contact form. It is supplied with a 1 m cable in horizontal orientation and has a 2 × 2 mm minimum contact gap. Operating speed ranges from 1 mm/s to 0.5 m/s, while IP67 protection is specified. The D4F-102-1R belongs to the D4F Series within the metal roller plunger limit switch range from Omron. Its 1NC/1NO slow-action configuration, horizontal cable orientation, 1 m cable length, and metal roller identify this version and separate it from longer-cable D4F-102 variants using the same contact arrangement.

The Omron D4F-102-1R Limit Switch operates from 1 mm/s to 0.5 m/s. Mechanical operation frequency is 120 operations per minute, while electrical operation frequency is 30 operations per minute. With the 1 m cable, maximum contact resistance is 300 mΩ. Insulation resistance is 100 MΩ minimum, rated insulation voltage is 250 V, and frequency is 50/60 Hz. These values form the supporting electrical profile behind the metal roller plunger, 1NC/1NO contact form, slow-action mechanism, horizontal cable orientation, 1 m cable length, and 2 × 2 mm minimum contact gap.
Operating temperature ranges from -30 to 70°C with no icing, and humidity is 95% maximum. Malfunction vibration resistance is 10 to 55 Hz at 0.75 mm single amplitude. Destructive shock resistance is 1,000 m/s² minimum and malfunction shock resistance is 300 m/s² minimum. IP67 protection is also specified. The 300 mΩ resistance value corresponds to the 1 m cable, making cable length and contact resistance useful distinctions within the D4F-102 group. Within the D4F-102 group, the 1 m horizontal cable, 300 mΩ contact resistance, metal roller plunger, and 1NC/1NO slow-action contacts form the most specific combination for this model. For the corresponding 3 m horizontal version with the same actuator and 1NC/1NO contacts, see D4F-102-3R.
