RFID-Coded Non-Autonomous Safety Switch for Safety Door Position Monitoring
The COMITRONIC XORF-SA RFID-Coded Non-Autonomous Safety Switch provides RFID-based position monitoring of safety doors on wheeled vehicles, featuring 16 million codes, automatic code learning and a maximum activation distance of up to 24 mm.
Designed for safety door monitoring applications, the XORF-SA uses RFID coding to detect the position of a corresponding actuator. The sensor is suitable for metallic environments and incorporates an auto-learning function that allows code programming without a computer or additional software.
As a non-autonomous safety switch, the XORF-SA is intended for integration with an appropriate safety controller. When combined with the specified AWAX controller, the original product information states that the system can achieve a performance level of up to PL e and safety category up to 4.
RFID Coding and Safety Door Detection
The XORF-SA incorporates RFID technology with approximately 16 million available codes. Its detection system is described in the original product information as "inviolable multicode" encoding.
The sensor supports automatic code learning without the use of software or a PC. An integrated LED indicates code recognition, allowing users to identify the recognition status during operation.
The maximum activation distance is specified as up to 24 mm. Installation conditions, mounting position and the relationship between sensor and actuator should be considered when configuring the safety door monitoring arrangement.
Safety Outputs and AWAX Controller Integration
The XORF-SA provides two redundant normally open (NO) contacts, rated at 50 mA / 30 V, together with one auxiliary PNP output rated at 50 mA.
According to the original product information, integration with an AWAX controller can provide a performance level of up to PL e and safety category up to 4 under EN 954-1. The stated MTTFd value is 40 years.
These safety performance figures relate to the specified controller arrangement and must not be interpreted as standalone safety ratings of the XORF-SA sensor. The complete safety function should be assessed according to its actual system configuration.
Mechanical Construction and Installation
The XORF-SA uses a PA6 housing with an IP68 sealing specification. The sensor is provided with a 50 cm PUR cable and M12 connector for electrical connection.
The original product information specifies two mounting positions using double wall brackets, together with four tamper-proof M4 attachment screws. A BH4 base option is also identified.
These construction and installation details should be considered when planning sensor placement, cable routing and actuator alignment.

Safety Switch Selection and Application Requirements
When selecting an RFID-coded safety switch, consider the safety door arrangement, required detection distance, electrical connection, environmental conditions and safety controller compatibility.
The XORF-SA provides RFID-coded position detection and redundant contacts for integration into a compatible safety control system. Its non-autonomous design means that the specified controller arrangement, complete safety circuit and installation requirements must be evaluated together.
For applications requiring a specific Performance Level or Safety Category, the complete safety function should be validated against the applicable system requirements. The stated PL e and Category 4 figures are conditional on the specified AWAX controller integration.
Discuss your safety door monitoring requirements, controller compatibility and installation conditions to determine whether the XORF-SA is suitable for your intended application.
