描述 Description

SMART Position Sensor, SPS Series, 75 mm linear configuration, 0 mm to 75 mm [0 in to 2.95 in] sensing range, 6 Vdc to 24 Vdc supply voltage, 0 Vdc to 5 Vdc analog output, magnet included.The SMART Position Sensor is one of the most durable, adaptable, and lightweight linear position sensors available in the industry, enabling highly accurate motion control and improving operation efficiency and safety. Its simple, non-contact design eliminates mechanical failure mechanisms, reducing wear and tear, improving reliability and durability, and minimizing downtime.
The SMART Position Sensor is a non-contacting sensing solution for absolute position sensing with enhanced accuracy. It senses the position of a magnet relative to the sensor in one of two available sensing ranges:

·0 mm to 35 mm [0 in to 1.38 in]
·0 mm to 75 mm [0 in to 2.95 in]
·0 mm to 225 mm [0 in to 8.86 in]
These sensors uses a patented combination of an ASIC (Application-Specific Integrated Circuit) and an array of MR (magnetoresistive) sensors to accurately and reliably determine the position of a magnet attached to a moving object so that the object's position can be determined or controlled.
The MR array measures the output of the MR sensors mounted along the magnet's direction of travel. The output and the MR sensor sequence determine the nearest pair of MR sensors to the center of the magnet location. The output of these two MR sensors is then used to determine the position of the magnet between them.
With this sensor, Honeywell has utilized MR technology through the ASIC at a level never before accomplished.
The SMART Position Sensor is available in both analog output (35 mm, 75 mm and 225 mm configurations) and digital output (225 mm configuration only) for use in control systems requiring a RS232-type interface with a 57.6 kbits/s baud rate.
Other configurations are in development.

特性 Features

·Reliable, durable: Non-contact design reduces wear and tear, improving reliability and durability, and minimizing downtime
·Easy to install: Installation takes four simple steps (1: position device; 2: drill holes; 3: mount sensor; 4: locate magnet/make electrical connection) vs. up to 14 steps some competitive products require, simplifying installation and reducing set-up costs
·Rugged: As there are no moving parts within the sensor, Honeywell utilizes unique packaging materials that make the sensor more resistant to vibration, shock, and extreme temperatures
·Flexible: Air gap of up to 8,5 ±1,0 mm [0.334 ±0.039 in] between sensor and magnet, and variety of output options (analog standard and other RS232-type baud rates) expands application opportunities
·Cost effective: Adaptable, non-contacting design allows customers to eliminate unnecessary connections for installation, thereby reducing installation steps, installation time, and components
·Accurate: 35 mm configuration accurately measures values down to 0,04 mm [0.0016 in], 75 mm configuration accurately measures values down to 0,05 mm [0.002 in], while 225 mm configuration accurately measures value down to 0,14 mm [0.0055 in] (analog) and 0,0035 mm [0.000137 in] (digital)
·Adaptable: Electronics on board allow for flexible packaging and component compatibility with existing systems
·Lightweight: More than 50% lighter in weight than LVDT (Linear Variable Differential Transformer) technology
·Simplifies design-in: Easy-to-configure sensor array fits virtually any linear movement path
·Self-diagnostics feature: Can reduce equipment downtime by providing predictive maintenance input
·Combined patented MR sensor and ASIC technology: Provides enhanced differentiation and performance
·IP67 and IP69K sealing: Allows use in many harsh applications
·Qualified for automotive grade EMI/EMC specification: Provides protection against environmental frequencies (35 mm configuration only)
·RoHS-compliant materials meet Directive 2002/95/EC

應(yīng)用 Application

(Applies to all configurations except where noted.)Industrial:
·Valve position: May be used to monitor valve position so the desired amount of liquid is delivered based on the position of the valve that is opening/closing, and how long open/closed (e.g., bottling machines, food/chemical processing, water handling equipment).
·Material handling: May be used on a lifting device that moves cartons from one conveyor belt to another.
·Plastic molding: May be used for injection positioning.
·Cutting and slitting: May be used in paper mills to accurately control the location of the slitter before it cuts.
·Wafer handling: May be used to monitor if parts are properly placed.
·CNC machines: May be used to monitor tool depth and direction of travel.Transportation:
·Engine transmissions: May be used for gear shift position for trucks (35 mm configuration only).
·Passenger bus level position: May be used for passenger bus leveling to simplify access for passengers and luggage.
·Truck-mounted crane outrigger position: May be used to determine that the outriggers are fully deployed before the lifting of objects can begin.
·Heavy equipment attachment identification: May be used to sense which attachments are being deployed onto heavy equipment by the strategic placement of the magnet to the sensor. The corresponding output indicates to the operator and control system which attachment is connected.
·Hydraulic cylinders: May be used on non-ferrous hydraulic cylinders for non-contact stroke position (225 mm configuration only).
·Marine motors: May be used for trim position on inboard/outboard motors for enhanced durability and performance.Aerospace:
·Aircraft actuators: May be used to control actuator position on multiple applications in the aircraft, helping to regulate airflow to engines and environmental systems.
