Frequently Asked Questions
Q: What is the maximum detection range of this photoelectric beam sensor?
A: The Asia-Teco 218E photoelectric beam sensor has a maximum transmitter-to-receiver sensing distance of 10 metres (approximately 33 feet), making it suitable for wide doorways, gates, and industrial entryways.
Q: Can I use this infrared safety sensor with both AC and DC power supplies?
A: Yes. The sensor accepts AC or DC voltages from 12V to 36V, so it is compatible with a wide range of control panels, transformers, and power supplies commonly used in automatic door and gate installations.
Q: What is the difference between single-beam and double-beam mode?
A: In single-beam mode, one infrared beam spans between the transmitter and receiver — ideal for compact or standard door openings. Double-beam mode creates two parallel beams for enhanced detection reliability, reducing the chance of small objects passing undetected. The 218E allows you to choose whichever configuration suits your application.
Q: What does "Fail Secure" security mode mean?
A: In Fail Secure mode, if the sensor loses power or detects a fault, the output defaults to the locked/safe position — meaning the controlled door or gate will not open unexpectedly. This is the preferred configuration for access-control and safety-critical installations.
Q: Is this sensor suitable for outdoor installation?
A: The 218E is rated for operating temperatures from –42 °C to +45 °C and humidity up to 90% RH, making it well-suited for sheltered outdoor locations such as covered garage entrances, loading docks, and outdoor gate posts. For exposed outdoor environments with direct rainfall, additional weatherproofing of the housing is recommended.
