PRMA1A12B is a DIP 14 series reed relay featuring a 1-Form-A contact configuration designed for reliable switching in industrial and telecommunications applications. The relay operates with a 12V nominal coil voltage (typical 30V, maximum 900V coil resistance of 1000O) and delivers a maximum switching voltage of 200V with a switching current of 0.5A and carry current of 2A. It provides stable contact resistance of 150mO maximum, bounce-free operation, and supports switching frequencies up to 500Hz with a long operational life exceeding 1 billion cycles. The device is epoxy molded for automatic PCB insertion, offers 4000Vac input-output isolation, and is UL and CSA approved, making it suitable for automatic test equipment, process control, industrial automation, and telecommunications applications.
