Omron D4C-1220-A1 – D4C Compact Enclosed Limit Switch, Roller Lever, SPDT, 3 m Cable
The Omron D4C-1220-A1 is a compact enclosed limit switch from Omron’s D4C series. It has a roller lever actuator, an SPDT (1 NO + 1 NC) snap-action contact rated 5 A at 250 V AC / 4 A at 30 V DC, a rugged die-cast metal housing and a 3 m prewired cable. It is rated IP67.
The D4C is a slim, sealed limit switch designed for machines where space is limited and conditions are tough. Its triple-sealed construction keeps out water, oil and dust, and the oil-resistant cable suits machine tools and coolant-exposed areas. With a mechanical life of 10 million operations, it is a reliable choice for position and end-of-travel detection on moving machine parts.

D4C-1220-A1 or D4C-1220?
- D4C-1220-A1: roller lever, 3 m cable (this item)
- D4C-1220: standard roller lever version (R38 lever, Ø17.5 mm metal roller)
- D4C-3220: 400 V class / different rating version of the same actuator
- D4CC-3024 / D4CC-4024: connector types with roller lever
The “-A1” version differs from the standard D4C-1220 in the actuator. The lever length and roller must match the original switch so the cam or target operates it correctly. Our sales team can help you confirm the right version.
