The APAN3112 from Panasonic is a general purpose power relay designed for through-hole mounting applications requiring reliable switching of moderate current loads. This SPST-NO (Single Pole Single Throw - Normally Open, also known as 1 Form A) relay operates on a 12VDC coil voltage with a low coil current draw of just 9.2 mA, making it energy-efficient while maintaining a coil resistance of 1.31 kOhms. The relay is capable of switching up to 5 amperes and handles voltages up to 250VAC or 110VDC maximum, making it suitable for both AC and DC circuit applications across various power levels.
This relay addresses several critical design challenges including the need for reliable isolation between control and load circuits, compact footprint integration on printed circuit boards, and operation in demanding environmental conditions with its wide operating temperature range of -40°C to 90°C. The fully sealed construction provides enhanced protection against dust, moisture, and contaminants, ensuring long-term reliability in harsh environments. The contacts are made from silver nickel with gold plating, offering excellent conductivity, low contact resistance, and superior resistance to oxidation and wear over extended switching cycles.
Performance specifications include a fast operate time of 10 milliseconds and release time of 5 milliseconds, enabling responsive switching for time-sensitive applications. The relay has a must operate voltage of 8.4 VDC and must release voltage of 0.6 VDC, providing predictable switching thresholds. The non-latching coil type means the relay requires continuous power to maintain the closed contact state. Packaged in tubes with PC pin termination style for easy through-hole PCB mounting, this relay comes in quantities of 2040 units and is RoHS compliant, meeting modern environmental standards.
Primary applications span industrial automation, HVAC controls, automotive electronics, telecommunications equipment, security systems, appliance controls, and general-purpose switching tasks where moderate current handling and reliable operation are essential. The relay's sealed construction makes it particularly well-suited for applications exposed to environmental stresses or where contamination could affect performance.
Equivalent and alternative models include other relays in Panasonic's PA-N series with different coil voltages (such as APAN3105 for 5V, APAN3124 for 24V), as well as comparable general purpose SPST relays from manufacturers like Omron (G5V series), TE Connectivity (Potter & Brumfield V23026 series), Fujitsu (FTR-F1 series), Song Chuan (833H series), and Hongfa (HF115F series) that offer similar current ratings, coil voltages, and form factors for direct replacement or design alternatives.
