Time Mark Corporation- Electromechanical Relay

Time Mark Corporation is a leading manufacturer of industrial monitoring and control devices, headquartered in Tulsa, Oklahoma, USA. Founded in early 1972 and incorporated on May 2, 1972, the company initially focused on developing monitors for three-phase power line condition sensing. Over five decades, Time Mark has expanded its product portfolio to address diverse customer needs in motor and power system protection. Its core product lines include 3-phase monitors, voltage sensors, current monitors, alternator controls, and time delay relays. The company's 3-phase monitor series detects faults such as phase loss, reversal, undervoltage, and overvoltage, safeguarding critical equipment. Time Mark also offers single-phase monitors, pump controllers, and specialized sensors for harsh environments. Their products are widely used in industrial automation, HVAC systems, agriculture, and water/wastewater management. Known for robust design and reliability, Time Mark serves a global customer base through a network of distributors. While not a top-tier semiconductor firm, the company holds a strong niche position in power monitoring and control devices, competing with brands like Macromatic and SymCom. With a commitment to quality, Time Mark provides custom solutions and maintains a reputation for responsive engineering support and durable products.
