Omron D4MC-3030 Limit Switch
Omron D4MC-3030 is a general-load limit switch with a unidirectional short hinge roller lever, 12.7 mm dia. × 7.5 mm plastic roller, and stainless-steel lever. It uses SPDT contacts, operates at 50/60 Hz, and carries IP67 protection. Maximum contact resistance is 15 mΩ, while mechanical durability is ten million operations minimum. The D4MC-3030 Short Hinge Roller Lever belongs to the D4MC Series within the Omron Hinge Lever Limit Switch Range from Omron Switching Product Range. Its unidirectional actuator, plastic roller, stainless-steel lever, SPDT contacts, and IP67 protection define the model.

The Omron D4MC-3030 Limit Switch uses a unidirectional short hinge roller lever with a 12.7 mm dia. × 7.5 mm plastic roller and stainless-steel lever. It has an SPDT contact form and is classified for general load. Frequency is specified at 50/60 Hz. Maximum contact resistance is 15 mΩ, while insulation resistance is 100 MΩ minimum at 500 VDC. Electrical durability is 500,000 operations minimum and mechanical durability is ten million operations minimum. The operating temperature range is -10 to 80°C, with relative humidity from 35 to 95%.
Pollution degree 3 is specified according to IEC947-5-1. Destructive shock resistance is listed at 1,000 m/s², and IP67 protection is specified. The supplied row does not provide a malfunction shock value, current rating, operating speed, or operation frequency, so none of those values are inferred from nearby D4MC models. The strongest source-supported specification cluster is unidirectional short hinge roller lever, 12.7 × 7.5 mm plastic roller, stainless-steel lever, SPDT contact form, general-load classification, 15 mΩ contact resistance, 100 MΩ insulation resistance, and ten-million-operation mechanical durability. This keeps the description tied directly to D4MC-3030. For another D4MC hinge roller-lever model, see D4MC-2000.
