Datasheet Summary
Powered by GS/AI

The Series 29 75A is a single-pole power relay designed for heavy-duty applications in transportation and industrial vehicles, featuring a sealed housing compliant with IP67 and IP6K9K standards. It supports continuous current of 75A at DC voltages up to 80V, with a 28VDC coil variant offering 10W power consumption and a coil resistance of 76Ω ±10%. The relay is rated for 6g shock and 4g vibration, operates from -40°C to +85°C, and has a mechanical life of 2 million cycles. Dimensions are 62mm length, 76mm width, and 50mm height, with M3.5 and M5 screw terminals for coil and main contacts respectively. Mounting is by chassis or brackets in standard side, short form side, or bottom configurations.
