The OMIH-SS-112L,300 is a general purpose power relay manufactured by Potter & Brumfield Relays, a division of TE Connectivity, designed to handle switching applications requiring robust current capacity exceeding 2 amps. This through-hole mounted relay features an SPDT (Single Pole Double Throw, 1 Form C) contact configuration, enabling it to control a single circuit with both normally open and normally closed positions, making it versatile for various switching scenarios.
Operating on a 12VDC coil voltage with a coil current draw of just 45 milliamps and coil resistance of 270 ohms, this relay delivers reliable performance across an operating temperature range of -30°C to 70°C. The contacts are constructed from silver tin oxide (AgSnO) material, providing excellent electrical conductivity and arc resistance while capable of switching up to 16 amperes at 250VAC or 30VDC maximum. The relay features a sealed flux protection design that guards internal components against environmental contaminants during soldering and operation, with PC pin termination style for straightforward printed circuit board integration supplied in bulk packaging.
Performance characteristics include a 20 millisecond operate time and 8 millisecond release time, ensuring responsive switching action, while the must operate voltage of 9VDC and must release voltage of 0.6VDC provide predictable activation thresholds. The non-latching coil type means the relay requires continuous power to maintain the switched state, returning to its default position when de-energized. This RoHS3 compliant component addresses design challenges in applications requiring moderate to high current switching with compact footprint, reliable isolation between control and load circuits, and operation in varied environmental conditions.
Primary advantages include high contact current rating for power applications, sealed construction for enhanced reliability, wide operating temperature range for industrial environments, and fast switching speeds for responsive control. The relay finds application in industrial automation, HVAC controls, automotive systems, power distribution equipment, motor control circuits, lighting control systems, and general-purpose switching where dependable electromechanical isolation is required. Equivalent or alternative models within the same OMIH and OEG series from TE Connectivity include variants with different coil voltages such as OMIH-SS-105L (5VDC), OMIH-SS-124L (24VDC), and OMIH-SS-148L (48VDC), while comparable relays from other manufacturers include the Omron G2R series, Panasonic ALA series, and Hongfa HF115F series offering similar SPDT configurations and current ratings.
