Why Choose the Finder 077.T2 Adhesive Thermal Pad for Solid State Relays?
The Finder 077.T2 is a high-performance adhesive thermal interface pad designed to improve heat transfer between compatible Finder 77 Series solid state relays (SSRs) and their associated heat sinks or metal mounting surfaces. Developed as part of the Finder 77 Series thermal management accessories, it provides a practical solution for improving heat dissipation in industrial switching and automation installations.
Solid state relays generate heat during operation, particularly when switching high-current loads or operating at high switching frequencies. The Finder 077.T2 provides a thermally conductive interface between the relay mounting surface and the heat sink, helping reduce the effects of small surface irregularities and improving thermal contact. Its adhesive construction simplifies positioning during installation and helps keep the pad correctly located while the relay is secured.
Designed for single-phase and two-phase Finder 77 Series hockey puck solid state relays, the Finder 077.T2 supports effective thermal management in industrial control panels and machinery. It is suitable for use with compatible Finder heat sinks, including the 077.21, 077.13 and 077.08 models, as well as specified fan-assisted heat sink assemblies. The thermal pad is supplied as a pack of 10, making it convenient for panel builders, maintenance engineers and OEM manufacturers.

Reliable Thermal Management for Industrial Solid State Relays
Solid state relays are widely used in industrial automation because they provide fast, silent and contactless electrical switching. Unlike conventional electromechanical relays, SSRs use semiconductor devices to control electrical loads without mechanical contact movement. This makes them particularly suitable for applications involving frequent switching, temperature regulation and automated industrial processes.
However, semiconductor switching devices produce heat during operation. Effective heat dissipation is therefore essential for maintaining suitable operating temperatures and supporting long-term reliability. Depending on the relay's current rating, operating conditions and ambient temperature, a suitable heat sink or other thermal management arrangement may be required.
The Finder 077.T2 adhesive thermal pad provides a thermally conductive interface between the solid state relay and its mounting surface. By filling small gaps and surface irregularities, the pad improves thermal contact and helps transfer heat from the relay into the heat sink or metal panel, where it can be dissipated into the surrounding environment.
The adhesive feature distinguishes the Finder 077.T2 from the non-adhesive Finder 077.T1 thermal pad. This allows the installer to position the thermal interface material more conveniently during assembly, reducing the likelihood of the pad moving before the relay is mechanically secured.
Finder specifies the 077.T2 for selected single-phase and two-phase 77 Series SSRs. It can be used with compatible passive heat sinks, including the Finder 077.21, 077.13 and 077.08, and with selected fan-assisted heat sink assemblies for applications requiring additional cooling.
The Finder 077.T2 is a thermal interface accessory rather than a standalone heat sink. It does not actively cool the relay or replace the need for an appropriately rated heat sink. Correct relay selection, mounting pressure, heat sink sizing, ventilation and ambient temperature must all be considered to ensure the complete assembly operates within the manufacturer's specified thermal limits.

Frequently Asked Questions
What is the Finder 077.T2 used for?
The Finder 077.T2 is an adhesive thermal interface pad designed to improve heat transfer between compatible Finder 77 Series solid state relays and their heat sinks or metal mounting surfaces. It helps improve thermal contact and supports effective heat dissipation in industrial switching applications.
What is the difference between the Finder 077.T1 and 077.T2?
Both products are thermal interface pads designed for compatible Finder 77 Series single-phase and two-phase solid state relays. The main difference is that the Finder 077.T2 features an adhesive construction to facilitate positioning during installation, while the Finder 077.T1 is the non-adhesive version.
Which solid state relays are compatible with the Finder 077.T2?
The Finder 077.T2 is designed for selected Finder 77 Series single-phase and two-phase hockey puck SSRs, including the 77.A1, 77.B1, 77.D1, 77.F1, 77.G1, 77.H1, 77.A2, 77.C2 and 77.E2 types. The correct combination of relay, thermal pad and heat sink should be selected according to Finder's compatibility information.
Can the Finder 077.T2 replace a heat sink?
No. The Finder 077.T2 is a thermal interface pad, not a heat sink. It improves heat transfer from the relay to a suitable heat sink or metal mounting surface but does not independently provide the cooling capacity required for high-current operation. Heat sink selection must be based on the relay's thermal requirements and installation conditions.
How many thermal pads are supplied with the Finder 077.T2?
The Finder 077.T2 is available as a pack of 10 adhesive thermal pads. This makes it suitable for control panel assembly, OEM production, maintenance work and installations involving multiple compatible solid state relays.
