Cleveland, Ohio—EMX Industries says it's the first manufacturer of photoeye access control products to offer a solar panel power option for its photoelectric emitters. The company says its SP44 solar panel, for its P44 Thru-beam Photoelectric Sensor/Transmitter, will extend emitter battery life by up to two years.
The P44’s emitter is powered by a nine-volt alkaline battery, which would otherwise normally last for 150 days or so. Measuring just 2.7-by-1.2-by-0.28 inches, the SP44 can be located almost anywhere in sunlight. A 20-foot, two-conductor cable connects the SP44 to the P44 power input terminals.
In operation, the SP44 powers the P44 emitter during the day (9 VDC floating charge on the P44’s alkaline battery); the emitter is powered by the battery at night. A green LED on the P44 emitter indicates the power-on condition. The working range between the P44 emitter and its receiver (which activates a relay when the light beam is broken) is up to 50 feet, and thus it's suited for such applications as garage door openers. The receiver is immune to incidental light up to an intensity of 5000 lux at 3000°K.

The Model SP44 Solar Panel is priced at about $43; availability is 4 weeks ARO.
