PRMA1B05C is a DIP 14 series reed relay featuring a 1-Form-B contact configuration designed for reliable switching in compact applications. The relay operates at a nominal coil voltage of 5V with a typical coil resistance of 500 O and a nominal input power of 50 mW. It provides a maximum switching voltage of 500V DC/Peak AC with a maximum switching current of 2A and a carry current rating of 3A, delivering a maximum contact rating of 50 Watts. The relay exhibits stable contact resistance with a typical static contact resistance of 65 mO and features mercury contacts for bounce-free operation. With an insulation resistance of 10¹° O and dielectric strength between contacts of 1400–2000 VDC/Peak AC, the PRMA1B05C is well-suited for automatic test equipment, process control, industrial automation, and telecommunications applications requiring high reliability and long operational life exceeding 1 billion operations.
