EE-SPW311 Miniature Through-Beam Photoelectric Sensor, 1 m Range, NPN Open-Collector Dark-ON - 1 Unit

This listing is for the EE-SPW311 miniature through-beam photoelectric sensor. The sensor is designed for presence/absence and object-detection tasks where a compact through-beam transmitter/receiver arrangement is used. Key technical details include an approximate sensing distance of 1 m (39.37") under typical conditions, an operating voltage range of 5-24 V DC, and an NPN open-collector, Dark-ON output. The sensor uses light modulation to reduce interference from ambient light and includes a visible indicator for quick status checks. Sold as a single sensor unit; confirm the EE-SPW311 model number and required wiring before fitting into your system.

• Replacement for EE-SPW311 through-beam photoelectric sensor; matches EE-SPW311 model code for direct fit applications.
• Through-beam sensing with approx. 1 m (39.37") detection range under typical conditions for small-part and presence/absence detection.
• Electrical: operates from 5 to 24 V DC and provides an NPN open-collector output configured Dark-ON (active when beam is blocked).
• Miniature sensor body for compact mounting; visible light indicator and light-modulation design reduce external light interference for stable switching.
• Sold as a single sensor (1 unit). Included components: EE-SPW311 photoelectric sensor (1 unit). Verify model and wiring compatibility before installation.
