The SL-TNR series offers a cost-effective and versatile solution for protecting a perimeter, where cabling is an issue or inconvenient. Ideal for small perimeters, flat roofs, and open areas, the active infrared dual beam set offers a lot of flexibility with its hybrid power options, where the transmitter is powered by Saft LSH-20 batteries, and the receiver can be hardwired. The SL-TNR series utilizes high-grade aspherical lenses and also has an anti-frost design with IP65 weather protection to improve its durability during harsh weather conditions.

200ft outdoor / 400ft indoor hybrid battery-powered photoelectric detector - Receiver: hardwired, transmitter: battery-powered. PCU-5 and 2 batteries included.

Applications: Ideal for small perimeters, flat roofs, and open areas.

Hybrid: Hardwired Receiver
For site configurations where one beam is close to a main power source but the other beam needs to be wireless, the SL-TNR offers the option to hardwire the infrared beam receiver with the included PCU-5 power converter.

Wireless: With High Density Lithium Batteries
The SL-TNR series has been designed to work with D-size lithium batteries, and OPTEX recommends the Saft LSH-20 battery. Battery life expectancy is approximately 5 years when using the LSH-20 batteries in both the transmitter and the receiver (4 batteries in total). LSH-20 batteries could also power the wireless transmitter when using the battery common unit BCU-5.
