Finder has introduced a series of microprocessor-based room thermostats providing a temperature setting resolution accuracy of 0.1ºC and advanced setting options to help reduce energy usage in residential and commercial environments.

Two new slimline thermostats are offered, each in a choice of grey or white housings:  the 1T.31 provides LCD display and pushbutton temperature setting, while the 1T.41 provides LED indication and analogue dial temperature setting.

For both variants, selection of off, winter/heating and summer/cooling setting modes is very simple with either LCD display or blue/red colour coded LED indicators ensuring quick recognition of operating status.

A day/night selector enables temperatures to be set back by 3ºC to help further reduce energy consumption while maintaining a comfortable ambient environment.  In addition, a +5ºC frost protection setting in the off mode helps protect against burst pipes.

Designed to be used together if required in the same building, both digital and analogue thermostats are presented in a consistent 18mm deep, IP20 rated housing for wall mounting.  The thermostat supply voltage is provided by two AAA 1.5V batteries and the output contact is a 5A, 230VAC changeover relay.

The new KF-series features exceptionally large isolation distances and offers high AC-23A motor ratings.  It covers the range from 16A to 32A and offers disconnect capability of up to 1000V according to IEC 947.  The rotary contact system incorporated in a new type of modular contact block allows high mechanical life expectancy and precise and reliable contact making.

The innovative modular system is both simple and very safe while offering enormous flexibility.  All available modules can be combined, exchanged or added in the field, as can the very precisely working cam-operated auxiliary contacts.  The position of the various modules in relation to each other
can be defined by the user or, if preferred, preassembled in the factory.

* Coupling profile determines pre-closing function of switched 4th pole,
  i.e. contact modules per se are always the same

* Rotating contact movement (instead of classical vertical lifting) allows
  big contact gaps
  high mechanical life expectancy
  very precise movement sequence
  self-cleaning contacts
  forced opening and closing of contacts

* Compact (very shallow) design

* Up to 1000V insulation voltage according to IEC possible

* Lateral drive possible (latching module not in the centre but on left or right hand side)

* Visible contacts (windows) available on request

* Design allows a big variation of terminal markings

* Removal from DIN rail can be done without tool change (screw driver for cross-recessed screws sufficient)

Economical, Reliable FSS-SMT Series Sensor Takes Up Less Space on the Printed Circuit Board;
SMT Packaging Often Eliminates Hand Soldering

Honeywell today introduced its smallest force sensor, the FSS-SMT Series, a low profile surface mount device that allows for automated assembly on a printed circuit board (PCB), often eliminating hand soldering and helping to reduce assembly costs. Cost-conscious customers will be attracted to the FSSSMT Series because it provides all four points of the Wheatstone bridg sensing element that gives them the flexibility to customize and integrate the sensor into other system electronics.

The FSS-SMT Series is designed to provide excellent reliability with a 20 million Mean Cycle To Failure (MCTF) at 25 °C [77 °F] rating that allows for consistent output over time, helping to reduce repairs or replacements. Low deflection (30 microns typical at full scale) and fast response help reduce measurement errors. Its stainless steel ball provides excellent mechanical stability, while the use of innovative elastomeric technology and engineered molded plastics results in load excitation capacities of 44 N over-force, making the sensor better able to handle unexpected increases in load.

Potential applications include occlusion detection, load and compression sensing, and variable tension control in ambulatory pumps, clinical diagnostic equipment, enteral pumps, infusion pumps, kidney dialysis machines, and wire bonding equipment.

The FSS-SMT Series is designed to provide precise and reliable force sensing performance in a compact commercial-grade package. The sensor incorporates Honeywell sensing technology that uses a specialized piezoresistive micromachined silicon sensing element. The low power consuming, unamplified, uncompensated Wheatstone bridge circuit design provides inherently stable millivolt output over the force range.

The FSS-SMT Series is an extension to Honeywell’s force sensor portfolio that includes the FSG Series, FSS Series, 1865 Series, and FS01/FS03 Series.

High-performing Sensors Designed to Help Reduce Manufacturing Costs
and Increase Application Flexibility

Honeywell introduces its HIH-5030/5031 Series humidity sensor that supports demanding system performance requirements, providing enhanced stability, accuracy, and response time over the entire humidity range of 0 %RH ~100 %RH.

The HIH-5030/5031 Series includes a Surface Mount Device (SMD) product on tape and reel that allows for use in automated, high-volume, lower cost pick-and-place manufacturing (1,000 units per reel), reducing lead misalignment to printed circuit board through-holes. Low supply voltage (down to 2.7 Vdc) and low current draw often allows for use in low drain, battery operated systems. Additionally, the HIH-5030/5031 Series’ accuracy, interchangeability, response time, and stability may contribute to cost savings over the life of the product.

The HIH-5030/3031 Series complements Honeywell’s existing HIH-4030/4031 Series of SMD humidity sensors. The Series consists of Complementary Metal Oxide Semiconductor (CMOS)-based humidity sensors that use capacitive technology to provide an analog voltage output in a solderable SMD package. The sensing element's multi-layer construction provides enhanced resistance to most application hazards such as condensation, dust, dirt, oils, and common environmental chemicals.

The HIH-5030 is a covered integrated circuit humidity sensor. The HIH-5031 is a covered, condensation-resistant, integrated circuit humidity sensor that is factoryfitted with a hydrophobic filter allowing it to be used in many condensing environments.

HIH-5030/5031 Series humidity sensors’ potential industrial and medical applications include air compressors and drying equipment, battery-powered systems, HVAC, OEM assemblies, process equipment, refrigeration, weather stations and meteorology equipment, hospital air compressors, infant incubators, microenvironments, sleep apnea equipment, and treadmill stress monitoring equipment.
