Low-Profile Thermostats

ATC’s range of low-profile thermostats offers users a unique combination of load and switching life-cycles in a conveniently thin package.  These thermostats have been expertly engineered to offer a minimum 100,000 contact operations at loads of up to 4A/250VAC.  The main four product types in this low-profile category are as follows;

PEPI J(A) Thermostats  –  This is the lowest profile thermostat in this category and has a live metal-case design.  The PEPI J(A) can be supplied with calibrations from 50°C to 160°C (in one degree steps) with a set-point tolerance of ±5K.  The temperature differential (or hysteresis) can be either 2K-10K or 5K-15K depending on the calibration setting.  Other temperature differentials also available according to the limits of the bimetal technology and temperature set-point.

Asahi US-630 Thermostats  –  Asahi’s US-630 plastic case thermostats use tried and tested 1/2″disc bimetal technology in their design.  The housing is only 6.1mm thick and a single thermostat or thermostat/thermal fuse combination can be supplied in this design.  Multiple thermostats can be supplied wired in series to give differing control levels with calibrations ranging from 0°C to 120°C.  Thermal differentials are typically 10±5K depending on the ultimate calibration setting.

Asahi US-638 Thermostats  –  Asahi’s US-638 thermostats are even thinner than the US-630 type at only 5.1mm thick.  They also use the same ultra-reliable 1/2″disc bimetal technology and can switch up to 100,000 cycles at 4A/250VAC.   Calibrations from 30°C to 100°C with tolerances of ±5K and thermal differentials of 10±5K are readily available.  The US-638 thermal control can also be supplied with fixing holes to help secure the thermostat in a precise location.

Matsuo MQT8K Thermostats  –  The MQT8K thermostat is the thinnest in the Matsuo range and is a superior twin-bimetal temperature switch offering unparalleled thermal control.  These precision bimetal thermostats have an internal structure that offers a unique combination of tolerance, differential and repeatability.  The twin bimetal system minimises calibration drift and ensures a long contact life from 100,000 cycles to 1 million cycles depending on the applied load.  Calibrations from -10°C up to 110°C with tolerances as small as ±1.5K.
