Q |
What are the SR13/SR15 Series position sensors? |
||||
A |
The SR13 series position sensor is a solid state, low cost, snap in sensor that produces either a digital or analog output when actuated. The SR15 sensor has the same rectangular package design but does not incorporate the snap, or locating pin on the bottom of the package. For further information, please refer to the SR13/SR15 product sheet.(pdf document) | ||||

Q |
What is the catalog nomenclature for the SR13 and SR15 sensors? |
||||
A |
The SR13 and SR15 can accept multiple product configurations
based on the SS400 series Hall Effect packages and also the TD5 temperature
sensor. In addition custom wire length and connectors can be specified based
on high volume opportunities. The following chart details possible sensing
component combinations for either the SR13 or SR15 that can be set up based
on opportunity:
SR13C = SS443A For further information on any of the above listings that are not set up, please contact your local Honeywell Sensing and Control sales office. |

Q |
How do SR13/15 sensors work? |
||||
A |
Honeywell solid state Hall effect position sensors produce
either a digital or analog output. Digital output sensors are in one of
two states — on or off. Analog sensors provide a continuous voltage
output which increases with a strong magnetic field and decreases with a
weak magnetic field.
There are two types of digital sensors, bipolar and unipolar. Bipolar sensors require positive gauss (south pole) to operate and negative gauss (north pole) to release. Unipolar sensors require a single magnetic pole (south) to operate. Release is obtained by moving the south pole away from the sensor. Analog sensors operate by proximity to either magnetic pole. Digital and analog sensor devices are operated by the magnetic field from a permanent magnet or an electromagnet. Actuation mode depends on the type of magnets used. |

Q |
Applications–where are the SR13/15 sensors most likely to be used? |
||||
A |
Sensors are best used in devices requiring valve position
sensing, robotics control, linear or rotary motion detection, length measurement,
flow sensing, RPM sensing, and security systems
These sensors can be used in the following applications: utility meters, fitness equipment, water softeners, gasoline pumps, balance scales, interlocks, flowmeters, vending machines, home appliances, computer equipment, medical instruments, copy machines, and office equipment |

Q |
What are some of the new and unique features of the SR13/15 sensors? |
||||
A |
The SR13/15 Series package enhancements permit quick and easy sensor installation, increasing the usability of the SS400 Series. These devices can be installed without additional mounting hardware. The snap-in and flat mount sensor packages can house any of the present SS400 Series sensors or any similarly sized sensing elements. The packages also provide varying 24AWG Radox leadwire lengths or connector capabilities. The SS400 Series position sensors have a thermally balanced integrated circuit that provides predictable performance for the –40癈 to +150癈 operating temperature range. The SS400 Series band gap regulation provides stable operation over 3.8 to 30 VDC. Current consumption is 10 mA at +40癈 ambient temperature. SS400 Series sensors are capable of continuous 20 mA sinking output. The sensors may be cycled as high as 50 mA maximum. Bipolar, unipolar and latching magnetics are available. | ||||

Q |
What are the new SR16/SR17 Series vane position sensors? |
||||
A |
The SR16/SR17 series hall effect sensors are designed to detect the presence, (or absence), of a ferrous vane, or flag. They offer 3 termination variations and two distinct package styles. The cost effective sensors are designed for fitness and information technology use in position and speed sensing applications where moderate exposure to electrical, chemical and mechanical environments can be expected.

Q |
How do the SR16 and SR17 Series vane position
sensors work? |
||||
A |
The SR16/SR17 Series vane position sensors contain an internally mounted magnet in one tower and a Hall effect sensor in the parallel tower. When the sensor is in the power on state, the magnet’s lines of flux saturate the Hall effect sensor and bias it to the on state. When a ferrous target is passed through the gap between the magnet and sensor, the magnetic field is interrupted and the sensor switches to an off state.

Q |
What are some of the new and unique features of the SR16/17 Series vane position sensors? |
||||
A |
The products offer a very robust package that can be used for speed sensing, position sensing or as a travel interrupter through the use of a ferrous vane, or flag. By using solid state Hall effect technology, the product will not be susceptible to humidity, dust or IR light interference. The choice of multiple packaging styles allow the customer to choose the best mounting and position sensing direction for their requirements. | ||||
