Small, Sensitive, Versatile Devices Provide a Faster Latch Response Time

Honeywell expands its magnetic position sensor product portfolio with the SS360NT/SS360ST/SS460S High Sensitivity Bipolar Latching Digital Hall-effect Sensor Integrated Circuits. Bipolar latching magnetics make these products well-suited for accurate speed sensing and revolutions-per-minute (RPM) measurement.

For brushless DC motor manufacturers that need latching sensor ICs with reliable, consistent performance for efficient and small designs, Honeywell’s family of new High Sensitivity Latching Digital Hall-effect Sensor ICs respond to low magnetic fields and offer consistent repeatability while providing the fastest response to a change in magnetic field for enhanced motor efficiency. These new sensors offer reliable switching points with high magnetic sensitivity of 30 G typical (55 G maximum) without using chopper stabilization on the Hall element, resulting in a clean output signal and the fastest latch response time in its class.

“Brushless DC motor manufacturers need sensors with high sensitivity, stable magnetics, and very fast response times to commutate the motor as efficiently as possible,” said Josh Edberg, global product marketing manager for Honeywell Sensing and Control. “By designing high-sensitivity sensor ICs without chopper stabilization, this family of sensors enables faster response times, which ultimately means more efficient motors.”

These small, sensitive, and versatile devices are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating North and South poles.

The SS360NT/SS360ST/SS460S can be used in a wide range of applications. Potential industrial/commercial applications include brushless dc motor commutation, flow-rate sensing for appliances, speed and RPM sensing, tachometer/counter pickup, motor and fan control, and robotics control. Potential transportation applications include speed and RPM sensing, tachometer/counter pickup, motor and fan control, electronic window lifts, and convertible roof position. Potential medical applications include medical equipment that utilizes electric motors.

These devices operate over the full temperature range of -40 °C to 150 °C [-40 °F to 302 °F]. Two package styles are available: Subminiature, SOT-23 surface mount package (SS360NT/SS360ST) supplied on tape and reel allows for compact design with automated component placement; the small, leaded, flat TO-92-style package (SS460S) allows for a compact PC board layout.

The SS360NT/SS360ST/SS460S offer a wide operating voltage range of 3 to 24 Vdc, allowing for potential use in a wide range of applications. Built-in reverse voltage enhances the protection of the sensor and the circuits. Their durable design allows operation up to 150 °C [302 °F]. Additionally, RoHS-compliant materials meet Directive 2002/95/EC.

Crydom’s proprietary thermal management technology and proven Solid State Relay expertise are now combined with advanced uP based timing in the new “SeriesOne DR” Timer line offering models with exceptional Solid State output ratings of either 6 amp AC and DC and 8 different precision timing functions with 18 variations in a compact 11mm wide DIN Rail mounted package designed for the direct control of a wide variety of resistive and inductive loads.

Crydom’s renowned Solid State Relay technology is now available combined with 8 different Microprocessor based timing functions including a total of 18 possible timing variations. Ideal for use in control panels for direct control of contactors, solenoids, motors, heaters, lights, etc. The SeriesOne DR Timer series is available with either 6 amp/24 to 280 VAC output rating or 6 amp/1 to 60 VDC output rating, both at 40°C ambient temperature…. ratings well in excess of most Solid State Output Timers in the market today, therefore allowing direct control of many loads thus eliminating the need for interfacing power relays often required for use with lower power timers.

Available timing functions include “A” & “At” delay on make, “B” single shot, “C” delay on break, “H” & “Ht” interval, “L” & “Li” repeat cycle, and “U” multifunction that includes A, At, Ac, B, Bw, C, D, Di, H, and Ht functions. Basic timing function selection is user settable via screw slot rotary switches on the side of the SeriesOne DR Timers, while unit and fine timing adjustments are made on the front panel of the Timers. This arrangement provides easy access to Technicians for simple timing adjustments but significantly reduces accidental changes to the basic function.

Control for the SeriesOne DR Timers, depending on model, is 12 to 24 VAC/DC for all models, with options of either 90 to 140 VAC or 180 to 240 VAC for AC outputs only. All Crydom SeriesOne DR Timers are UL listed and cUL recognized, UL Motor Control rated, RoHS and China RoHS compliant, and CE certified to the Low Voltage and EMC Directives.

Supervision of a large and noisy assembly or production area can often be difficult as traditional smaller sized beacons and sounders can sometime be ignored.

Very bright, very loud and very big.....The new 430 series offers a range of LED lights, permanent, flash, rotating and the strobe-like EVS light. The integral sounder has a massive output adjustable up to 105dB with 32 available tones to select from.  The unit is approximately twice as large (407mm high) as the traditional combination unit available.

The optical and audible signals can be triggered separately to provide users with the option of activating just one signal type or both at the same time to generate a maximum level of awareness.

In addition to versions for base mounting, the signal devices are also available with a practical mounting bracket.  Long Life and maintenance-free Using the latest LED technology gives the unit a life of typically up to 100,000 hours.

Where the need to control lighting, temperature or other functions according to daylight hours exists, Finder has developed an innovative, easily programmable time switch which employs a unique digital program to calculate sunrise and sunset times by simply entering the location’s postcode with a single joystick.

With ever increasing pressures to reduce energy consumption, Finder’s Astro 12.81 time switch will control lighting, heating/cooling and humidity equipment in commercial, residential and industrial applications wherever sunrise and sunset times are critical in determining operational times. The Astro’s micro-controller stores postcode data from 16 European countries, including the UK, allowing for a precise calculation of seasonal sunrise and sunset times through date and location coordinates. The Astro is also programmable using geographical coordinates, settable between 30°S and 64°N; 16°W and 50°E. The Astro will also automatically compensate, should European Summer Time be enabled.

For added flexibility, the output switching can be advanced or retarded about the calculated sunrise (or sunset) time in 10-minute increments—up to a maximum of 90 minutes. A manual override of the output status allows for maintenance or one-off events. With a 16A 250vac rated output contact and a 120A 5ms peak current rating, the Astro time switch is capable of directly switching 2000W halogen, 750W compensated fluorescent, 200W CFL or LED lamp loads and AC15 loads up to 750 VA.

The integral back-up battery, which is easily replaceable from the front, features an automatic power save mode which helps extend battery life.
