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.
- Replacement for EE-SPW311 through-beam photoelectric sensor; matches EE-SPW311 model code for compatibility reference 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.
Model selection
The manufacturer table describes EE-SPW311 as a set including an emitter and a receiver. This listing says one unit; whether both parts and the needed connections are included has not been verified. Confirm the contents before ordering. This reference does not verify the supplied item or compatibility.
