Bluetooth Interface for Safety Light Curtains

　　Schmersal Group has introduced the SLC440/COM, a pioneering safety light curtain equipped with a built-in Bluetooth Low Energy (BLE) interface. This photoelectric protective device (AOPD) allows smartphones or tablets to access real-time status and diagnostic data of the equipment through the BLE interface. With an integrated setup assistant on your smartphone or tablet, activating the Bluetooth function is effortless. Additionally, it can be used to record and save data, such as repeated tests or data for predictive maintenance.

　　Schmersal's developed app facilitates seamless data transfer to smartphones/tablets (Android and iOS systems). BLE, standing for Bluetooth Low Energy, is a radio system designed for secure data transmission over short distances.

　　Exclusive Wide-Range Capability

　　This technological innovation in data transmission range for photoelectric safety systems is unparalleled. Previously, diagnostic tools based on NFC technology with a detection range of mere centimeters were the only options available in the market. In contrast, the BLE function boasts a detection range over 100 times longer, reaching up to 5 meters. This makes the BLE interface the ideal choice when photoelectric safety systems are located in hard-to-reach areas. The wider applicability of BLE is further enhanced by the fact that not all smartphones or tablets are equipped with NFC, but most come with Bluetooth. As Bluetooth is an international industrial standard, the 440/COM series safety light curtains with BLE interfaces can be used globally.

　　Enhancing Efficiency: Real-Time Access to Status Data

　　The SLC440/COM series safety light curtains with BLE functionality significantly boost production efficiency. With convenient real-time access to the status data of the light curtains, errors can be resolved promptly, improving the overall machine productivity. Timely access to status information and diagnostic data enables faster reactivation of programs, especially after system shutdowns triggered by detected hazards.

　　Compared to traditional Bluetooth, BLE significantly reduces energy consumption and costs while maintaining a similarly high communication range, representing a genuine economic innovation.
