Slot sensor for tight-gap edge and flag detection
The Omron EE-SX974-C1 is a through-beam slot sensor in a chassis-mount package with M3 screw fixing, designed for detecting the presence or absence of an object passing through a 0.02 mm gap.
Temperature range — -25°C to 85°C
It is not rated for extended outdoor exposure or condensing humidity — if the machine sits in a washdown zone, consider an IP67-rated alternative like the E3T-FT11 series instead.
