Specifications
The document outlines the specifications for OPTEX's short-range photoelectric detectors, specifically the AX-TN/TF series. These detectors are designed for high durability and stable detection performance, reducing false alarms in severe outdoor environments.

Dimensions and Options
The detectors come with various components such as the HU-3 Heating Unit, BC-3 Back Cover, and PSC-3 Pole Side Cover. They are designed to be installed on poles, with options for covering mounting poles. The heating unit is suitable for severe low-temperature conditions, operating at 24V DC/AC with a maximum current of 420mA.

Detection and Performance
The AX-TN/TF series offers selectable beam frequencies and a maximum detection range of up to 200m (700ft) for the AX-70TN model. The detectors use infrared beam interruption detection and have a selectable interruption period between 50, 100, 250, and 500 milliseconds. They are equipped with a D.Q. circuit to send trouble signals when beam strength is compromised.

Environmental and Durability Features
The detectors are IP65 rated, ensuring protection against dust and water jets. They include rubber packing to prevent ingress of rain, dust, and insects. The units are tested for water resistance using a water jet stream, confirming their durability in outdoor conditions.

Additional Features
The detectors feature an anti-frost hood cover, an Automatic Gain Control (A.G.C.) circuit for adjusting sensitivity, and a high-grade spherical lens for precise beam definition. They also offer easy angle adjustment and a 99% beam blocking stability to maintain operation in adverse weather conditions.

Installation and Maintenance
The detectors allow for wall and pole mounting, with easy angle adjustments for beam alignment. The alignment condition is visually displayed using an LED indicator, facilitating accurate setup.

Certifications and Compliance
OPTEX is ISO 9001 and ISO 14001 certified, and the products conform to the EMC Directive 89/336 ECC. The document emphasizes the environmental responsibility of using recycled paper for the catalogue.
