Time Mark

What Time Mark does

Time Mark Corporation is a privately held designer and manufacturer of industrial electrical control and monitoring devices headquartered at 11440 East Pine Street, Tulsa, Oklahoma, founded in 1972 and operating continuously for over 50 years. The company builds approximately 658 SKUs across ten product categories, including 3-phase monitors, voltage and frequency monitors, current monitors, alternating relays, multi-stage alternators, liquid level controls, time delay relays, transformers and transducers, accessories, and custom/OEM products. Core technology centers on proprietary microcontroller-based sensing circuits combined with electromechanical and solid-state relays, with differentiated offerings such as the SS-480/SS-575 Smart Socket (which prevents voltage rise at pin connections when a relay is removed) and the TMC430 Pump Controller, the most advanced offering with 4-20mA input and up to three-pump control. Several SKUs carry UL Recognized, CSA Certified, and CE certifications, and select Smart Socket combinations are backed by an exclusive 5-Year Unconditional Warranty.

The company sells exclusively through an authorized distributor network rather than direct-to-end-user channels. Customers locate products via the company website, the Find a Distributor and Find A Sales Rep tools, and the Octopart.com marketplace, which surfaces distributor availability and pricing from each product page. End customers are industrial equipment manufacturers and operators using Time Mark devices for motor protection, pump control, HVAC equipment protection, air compressor monitoring, and industrial process control. Pricing is not publicly disclosed; commercial terms are set per distributor. Operating geographies are centered in North America, with international demand served through the global distributor network.

Products and services

• 3-Phase Monitors Industrial control devices that continuously monitor 3-phase power systems for phase loss, low voltage, phase reversal, and other fault conditions to protect motors and equipment. Used by industrial equipment operators and OEMs.
• 3-Phase Testers Portable or fixed devices used to test and verify 3-phase power systems, including motor rotation indicators for proper phase sequence verification. Used by installers, maintenance crews, and OEMs.
• Liquid Level Controls Controls for monitoring and managing liquid levels in tanks and pumping systems, including pump-up, pump-down, dual-level control, and alarm functionality for industrial applications. Includes the advanced TMC430 pump management system.
• Time Delay Relays Electromechanical or solid-state relays with adjustable timing functions for delaying activation or deactivation of circuits in industrial control applications.
• Special Controls Custom and specialized industrial control devices designed for unique application requirements beyond standard monitoring functions, including the Model 60 Bistable Impulse Latching Relay.
• Voltage & Frequency Monitors Devices that monitor AC voltage levels and frequency, providing over/under voltage protection and rapid cycling detection to safeguard sensitive equipment.
• Current Monitors Devices that monitor AC current levels to detect overcurrent or undercurrent conditions, protecting motors and equipment from damage due to abnormal current flow.
• Alternating Relays Relays designed to alternate between two loads (such as pumps) to equalize run time, commonly used in duplex pumping systems and multi-stage motor control applications.
• Transformers & Transducers Current transformers and transducers that convert AC current to proportional DC signals for use with monitoring and control systems, including ring-type and open-frame CTs in various current ratings.
• Accessories Supporting products including sockets, voltage extenders, general purpose relays, DIN rail adapters, safety enclosures, hold-down clamps, and smart sockets for use with Time Mark monitoring devices.

Broad incumbents

• Siemens: SIRIUS and SIMOCODE motor protection and monitoring lines, plus broader industrial automation. Directly competes with Time Mark in 3-phase/voltage/current monitoring for industrial OEMs, though with substantially broader software and connectivity offerings.
• Littelfuse: Diversified industrial protection manufacturer with a strong relay, motor protection and power quality portfolio. Competes with Time Mark on protection relays and 3-phase monitoring while serving a much broader electronics customer base.
• ABB: Global industrial automation and motor protection supplier offering electronic motor controllers, relays and power quality devices. Competes with Time Mark in industrial motor and 3-phase protection applications across large OEM and end-user accounts.
• Schneider Electric: Global automation and motor-protection leader (including the legacy Square D brand) offering phase, voltage and current monitoring relays across a much broader industrial automation portfolio. Highly comparable product category but at vastly larger scale and with networked/IoT capabilities Time Mark lacks.
• Rockwell Automation (Allen-Bradley): Allen-Bradley motor protection relays and ArmorStart starters for industrial applications. Competes with Time Mark in industrial motor control and pump protection, especially within Logix-based automation ecosystems.
• Eaton: Major manufacturer of motor protection relays, power quality monitoring and industrial control components (e.g., Power Xpert, C441). Overlaps directly with Time Mark's phase/voltage/current monitoring and relay offerings as part of a much wider electrical portfolio.
• Phoenix Contact: Industrial connection, automation and monitoring solutions including motor management and current/voltage monitoring devices. Overlaps with Time Mark's protection and monitoring product lines and competes for OEM panel-builder specifications.

Regional players

• Murr Elektronik: European-focused manufacturer of industrial controls, relays, transformers and monitoring devices. Comparable product category to Time Mark but primarily serves European OEM customers, making it a regional competitor for any international expansion.

Emerging players

• Selec Controls: Manufacturer of industrial meters, relays, current transformers and pump controllers with strong presence in Asia and growing US distribution. Highly comparable catalog to Time Mark with broader low-cost offerings and more recent digital/IoT product launches.

Direct peers

• Macromatic Industrial Controls: Closest pure-play peer: a private US manufacturer specializing in industrial control relays, phase/voltage/current monitors, alternators and pump controls. Very similar product mix, customer base (US OEMs and panel builders) and channel model to Time Mark.
