Datasheet Summary
Powered by GS/AI

The Series 29 120A relay is a single-pole, single-throw normally open power relay designed for high-current applications in automotive and heavy-duty vehicles. It features an environmentally sealed housing compliant with IP67 and IP6K9K standards, and is rated for continuous operation at 120A DC with a contact voltage rating up to 28VDC. The relay supports 28VDC coil voltage with a nominal coil power of 10W and coil resistance of 80Ω ±10%. It offers multiple mounting options including standard side, short form side, bottom, and long form side mounting, with M4 screw terminals for the coil and M8 male terminals for the main contacts. The operating temperature range is -40°C to +85°C, with 6g shock and 4g vibration resistance. Mechanical life is rated at 2,000,000 cycles. The product dimensions are 80mm in length, 62mm in width, and 50.5mm in height.
