Rugged and Reliable Sensors for Harsh Environments

Allied Electronics & Automation supplies Contrinex EXTREME inductive sensors from the full Inox familyAllied Electronics & Automation supplies Contrinex EXTREME inductive sensors from the full Inox family. Rugged, reliable, and highly accurate, the Extreme range is at home in the most challenging circumstances. Thanks to one-piece stainless-steel (V2A/AISI 303) construction and a hermetically sealed cable entry, extreme sensors are corrosion-resistant, impervious to oil, and pressure-resistant to 100 bar. Developed to withstand the harshest industrial operating conditions, Extreme sensors are rated to IP68 and IP69K, delivering fit-and-forget performance with minimal downtime. With operating distances up to 40 mm, the Extreme range senses both ferrous and non-ferrous materials with Factor 1 performance and is available in sizes from M8 to M30 and C23.

Mouser Electronics stocks the new Sensirion SHT41A Automotive Humidity and Temperature Sensors, which offer a 2.3V to 5.5V supply voltage range, AEC-Q100 qualification, and relative humidity accuracy of up to ±2%RH. The SHT41A series is a digital sensor platform designed to measure relative humidity and temperature with different accuracy gradings.

ICC supplies TE Sensor Solutions’ M5200 pressure transducersICC supplies TE Sensor Solutions’ M5200 pressure transducers, part of TE’s Microfused line. This modular solution offers maximum flexibility for different configurations and sets a new price performance standard for demanding commercial and heavy industrial applications. Ideal for low-to-mid volume OEMs, M5200 pressure transducers are designed for the measurement of liquid or gas pressure, even in difficult media like contaminated water, steam, and mildly corrosive fluids. The M5200 is compact, weatherproof, and has a wide temperature range (-40 °C to +125 °C operating temperature). Custom designs and additional configurations are available.

Lion Precision, a Carlisle Brand, offers the high-precision ECL202Lion Precision, a Carlisle Brand, offers the high-precision ECL202, an FPGA-based digital system with a digital core and push button controls. The switch output threshold is user adjustable by front panel and remote control. User selectable bandwidth and DIN rail mount electronics provide application flexibility. Key benefits include ranges from 0.25 mm to 15 mm, industry standard 0-10 VDC output, and setpoint contacts output. The probe can be used in wet and dirty environments. Probes can be ordered as vacuum-compatible.


Amphenol Telaire T9602 IP67 harsh environment humidity & temperature sensor supplied by AvnetAmphenol Telaire T9602 IP67 harsh environment humidity & temperature sensor supplied by Avnet is a fully calibrated and temperature-compensated combined humidity and temperature sensor supplied in a water-resistant IP67 package, making it the most advanced and cost-effective sensing solution for virtually any type of harsh environment application. Telaire T9602 provides linearized output signals in one of two interfaces – Digital (I2C) Output or Pulse Density Modulated (PDM) Output convertible to an analog signal – to meet a wider range of customer requirements.

METZ CONNECT M12 sensor / actuator connection cablesMETZ CONNECT M12 sensor / actuator connection cables with molded M12-A coded connectors meet the typical requirements of the automation industry. The sensor plugs are available in different designs as well as with various numbers of poles. The diverse range of sensor plugs is supplemented, among other things, with 360° shielded and unshielded variants. All connection cables are available in PUR and PVC cable quality.

RNC sensors from MolexRNC sensors from Molex reduce road noise within the vehicle cabin. Employing A2B technology, they convert vehicle chassis vibration into a signal that generates a cancellation soundwave, reducing unwanted noise within the cabin and increasing comfort for an improved driver/passenger experience. Molex’s sensors provide superior performance in harsh conditions. They are available in different housings, including an IP6K9K enclosure, to ensure greater protection from harsh conditions while enabling placement closest to the road noise. Detecting the sound at its source speeds processing of the noise-canceling signal; A2B technology also allows a higher number of signals per chain to be processed. Molex sensors are sensitive enough to measure and cancel road noise at slower vehicle speeds, giving designers greater flexibility in sensor placement while simplifying engineering.

antenna technologies

Wearin’, part of Conextivity Group along with Fischer Connectors, is an intelligent IoT platform that generates real-time insights by capturing in-mission data from connected sensors and devices. The connected platform digitalizes the real-time status of people in the field — their location, environment, and well-being — to detect and prevent crisis situations. A selection of sensors and devices is incorporated into workers’ and field operators’ gear, vehicles, and surroundings to capture and process critical data. This data is sent to both the user and the decision makers who need it, while automated alerts and two-way communication facilitate coordination and response. AI-powered data processing allows for incident detection, such as heat stress and acute stress, man down, or an attack on an armored vehicle, and helps prevent future risks.

TTI offers Honeywell’s MIP Series of heavy duty, media-isolated pressure transducersTTI offers Honeywell’s MIP Series of heavy duty, media-isolated pressure transducers in compact, stainless steel construction for use with a wide range of media, including aggressive fluids and water. The MIP Series provides a cost-competitive solution for wide-ranging potential applications in tough environments. It provides critical information about the sensor functionality and internal or external failure modes. MIP Series has multiple configuration possibilities, providing flexibility of use in the application with no up-front NRE or tooling charges and provides the necessary tough environmental capabilities, including long-term stability, insulation resistance, and dielectric strength, external freeze-thaw resistance, and EMC performance.

ept Flexlinkept’s flexilink board-to-board connectors protect sensors used close to machines and exposed to particularly harsh environmental influences. As a one-piece connection solution that does not require the conventional mating area, flexilink is a way to guarantee the necessary degree of reliability. Using a flexilink connector provides a durable, robust connection solution in which the contact area cannot be penetrated by an overmold material. Thanks to press-fit technology, flexilink connectors withstand shock loads of 50–200 g without contact interruption.
