Mechanical Temperature Switches
UFV729 Series
Mechanical Bimetal Temperature Switch
A compact mechanical bimetal temperature switch with configurable normally-open, normally-closed, or dual-contact output, 40 to 130 deg C set points, multiple probe and connection options, and IP65/IP67 protection.
RANGE40 to 130 deg C set point
OUTPUTNO / NC / NO + NC contacts
MATERIALBrass or stainless steel; custom options
PROTECTIONIP65 / IP67
Product overview
Application-focused measurement and switching.
The UFV729 Series uses a coiled bimetal element to actuate an internal mechanical switching mechanism at the selected temperature. The simple, power-independent sensing principle is suited to machinery and automation where a discrete temperature limit is required without electronic signal conditioning. Process connection, output contact, set point, probe geometry, material, and connector options can be configured for the installation.
Configuration note
Ratings, materials, interfaces, and approvals can vary by ordered configuration. CASCED INC confirms the controlled specification before order acceptance.
Key features
- Mechanical bimetal sensing with no external power required for the sensing mechanism
- Normally-open, normally-closed, or combined NO + NC contact configurations
- Set points from 40 to 130 deg C in 5 deg C increments
- Low-hysteresis switching for machinery and automation temperature limits
- Configurable process connections, probe lengths, probe diameters, and materials
- DIN 43650 or M12 electrical connection options with IP65/IP67 protection
