Adjustable Thermal Sensor Detects People Within A 10-ft. Range
The IR6000 series thermal sensing unit can be used as a sensor for detecting people standing within its detection spot. It can be used to auto-activate a system response in a wide range of applications, like kiosks, multimedia presentations, people counters, and CCTV security cameras. It operates on 12 V dc, and it measures just 1.5 by 2.5 by 1.5 in. Suited for overhead or ceiling-mount installations, it has a 6-in. spot size at a 10-ft. distance.
Its 10-ft. range is adjustable. Designers also can adjust the output delay so people can walk through the detection spot without causing an output change, eliminating unwanted responses. A built-in standard RJ-11 phone jack provides simple hookup of power and signal lines. Three models are available with three different outputs: an open collector, a relay contact, and a serial data output.

Position Sensor Provides Ratiometric Output Over 360°
The 601-1045 industrial position sensor boasts 5 million operating cycles with a radial load up to 200 g applied to the shaft. Its self-contained package provides over 360° of analog electrical output with no dead band. No external interface electronics are required. With its 5-V dc low-current supply and absolute positioning output, the 601-1045 presents a low-cost alternative to encoders.
The unit also features built-in reverse-polarity protection, a 50-µs angular response, sealing to IP54, and low power consumption. Measuring 44 by 33 by 20 mm, the 601-1045 weighs 30 g. It's housed in a fully insulated, molded plastic body with a stainless steel shaft. Gold-plated pins that are compatible with a standard mating connector provide the electrical connections.
In 100-unit batches, the 601-1045 costs $40. Delivery is from stock.

Wireless Transmitters Replace Cables For Remote Sensors
The HS-900 spread-spectrum frequency-hopping radio, which features integrated I/O, provides a secure, interference-free, wireless connection between remote sensors and an existing meter, PLC, or SCADA system. Rated as Class 1, Div. 2, each conduit-mounted transmitter has wiring connections for a single 4- through 20-mA signal and two digital inputs. A paired DIN rail-mounted receiver replicates the current as an output and has dry contacts to mimic the digital inputs. A third contact on the receiver indicates the RF link's status.
This radio also can transfer data up to 5 miles via line-of-sight using omnidirectional antennas. High-gain yagi directional antennas increase this distance. Communication through steel or concrete buildings is possible with reduced range. Hopping frequencies every 20 ms, the radio signal quickly avoids interference. Each HS-900 pair has a unique frequency-hopping pattern and address, so users can simultaneously employ multiple radios in the same area.

Electrolytic Tilt-Sensor Families Suit Broad Range Of Markets
Three families of electrolytic tilt sensors—the NA, the NB, and the NLC—target commercial and industrial markets. All of the models feature built-in temperature compensation. They're also immune to asymmetry of driving signal or accidental exposure to dc components in the driving source. Signal-conditioning circuitry is available.
Models in the NA series can be used in mobile satellite dishes, construction equipment, and other applications. The NB series of sensors targets the mid-operating range, with uses including leveling laser devices and security systems. And, the NLC line meets the electrical requirements of engineers with tight budgets.
Prices range from $16 to $30.

18-mm Photoelectric Sensors Compatible With Fiber Optics
The Series 18 line of diffuse, retroreflective and through-beam sensors provides noncontact detection of parts in counting, measuring, and positioning applications. Their manufacturer says they work well in tight spaces. They also can detect small objects at high speeds. Compatible with fiber optics, these photoelectric sensors come with high-visibility LED status indicators, along with light or dark output programming.
Sophisticated teach-in functions allow users to program the sensing range from 20 to 430 mm. Polarization filters let the sensors recognize highly reflective objects. Longer-range applications can take advantage of their alignment aid, soiled-lens-indicator LED, and side-mounted 270° potentiometer. Contact the company for pricing and availability information.
