Omron D4MC-1020 Limit Switch
Omron D4MC-1020 is a general-load limit switch with a short hinge lever made from stainless steel and an SPDT contact form. The model operates at 50/60 Hz and carries IP67 protection, while contact resistance is specified at 15 mΩ maximum. Mechanical durability is ten million operations minimum. Insulation resistance is 100 MΩ minimum at 500 VDC. The D4MC-1020 belongs to the D4MC Series within the Omron limit switch range from Omron. Its stainless-steel short hinge lever, general-load SPDT configuration, IP67 protection, and listed durability values form the main product attributes for identifying this D4MC model without adding unsupported application claims.

The Omron D4MC-1020 Limit Switch uses a short hinge lever made from stainless steel with an SPDT contact form for general load. It operates at 50/60 Hz and is specified with IP67 protection. Maximum contact resistance is 15 mΩ, while insulation resistance is 100 MΩ minimum at 500 VDC. The operating temperature range is -10 to 80°C with relative humidity from 35 to 95%. Pollution degree 3 is listed according to IEC947-5-1. Electrical durability is 500,000 operations minimum, and mechanical durability is ten million operations minimum, providing the main supporting electrical and endurance specifications behind the actuator and contact configuration.
Destructive shock resistance is specified at 1,000 m/s² maximum. The supplied row does not list a separate rated load value, malfunction shock value, operating speed, or operation frequency, so those details are not inferred from other D4MC models. For product identification, the most relevant specification cluster is D4MC Series, stainless-steel short hinge lever, SPDT contacts, general-load classification, IP67 protection, 15 mΩ maximum contact resistance, and ten-million-operation mechanical durability. These terms keep the content focused on the actual model data and its documented D4MC Series attributes rather than adding unsupported applications or performance claims.
