Barksdale Controls T2H-H352S Temperature Switch

Barksdale Controls T2H-H352S Temperature Switch is a dual remote-sensor, mechanical temperature switch designed for industrial temperature monitoring and control, with explosion-proof housing for demanding environments. The unit provides two independent SPDT outputs and can serve as a two-position controller, using two remote sensors to monitor distinct temperature points. It features an integrated terminal clip and a tamper-protected cover for setting the point in both °C and °F, and carries protection class ratings IP65 and NEMA 4/13 for rugged installation. The T2H family supports broad adjustable ranges, including -45 °C to +66 °C and +160 °C to +316 °C, depending on configuration, enabling precise control across a wide thermal band. Optional high-circuit disconnection with manual reset (RD micro switch) and a variety of micro-switch options (S, RD, M/GM variants) allow customization of the hysteresis and switching behavior, while the dual-switch arrangement can be used in multi-point monitoring or control schemes. Approvals for hazardous environments include Ex ia, with UL/CSA on request, and the product is positioned for IEC 61508 SIL2/3 suitability when configured. This model is part of Barksdale’s MT1H/T2H temperature switch lineage, combining robust construction with flexible set-point adjustment and multiple output channels to support industrial process control, equipment protection, and safety interlocks in challenging environments.
