Most models feature nickel plated brass (BN) and stainless steel (SS). Both flush mount and nonflush mount sensors are available. Nonflush sensors have larger sensing distances than their flush mount counterparts. All Inductive sensors meet IP67 (NEMA1, 3, 4, 6, 12, 13) protection levels. FLUSH MOUNT CYLINDRICAL SENSORS Flush Mounted, sometimes called embedded or shielded sensors, have electromagnetic fields concentrated directly in front of the sensing heads and may be mounted directly onto metal mounting brackets or embedded directly into metal without causing a false output. Figure 8 (located on page 7) also illustrates that on Cylindrical Flush Mount sensors there should be at least 1 diameter of distance between adjacent sensors, and no non-target metal surfaces should be less than 3 times the sensing distance Sn directly across from the sensing head. Also, two directly opposite sensors mounted in metal should be greater than 6 times the sensing distance apart. NON-FLUSH CYLINDRICAL SENSORS Sometimes called non-embedded or nonshielded, non-flush sensors have electromagnetic fields with a wide sensing angle and are unshielded (no metal surrounding the sensing head). Care must be taken to insure that no non-target metal comes in near proximity to the sensing head. Distances are demonstrated in Figure 8. Adjacent sensors should be separated by at least 2 times the diameter. Non-target metal should be at least 3 times the sensing distance directly across from the sensing head. Two directly opposite sensors should be at least 6 times the sensing distance apart. OUTPUT CONNECTIONS AC,DC – Normally Open (NO), and Normally Closed (NC). DC – Complementary output (NO/NC) available on some models. OUTPUT CABLES Cylindrical Sensors are provided with 2 meter PVC fixed cables. 5 meter PVC, 2 and 5 meter PUR cables are optional.

No physical contact is required nor desired. IPS's work best with ferrous metals, however, they also work well with non-ferrous metals (aluminum, brass, copper, etc.) at reduced sensing distances, s ee Fi g u r e 1. First introduced in the mid 60ʼs, Inductive Proximity Sensors were designed as an alternative to mechanical limit switches for many applications. Initially, IPS's were made with housings similar in size and dimension to the limit switch, but had short 4 sensing distances. Following very good results with these new devices, market pressure led to the development of larger sensors with increased sensing distances. Inductive Proximity Sensors have no moving parts, operate very fast, are extremely reliable, require no maintenance and operate under extreme environmental conditions. They typically interface with Programmable Logic Controllers (PLC) and personal computers with appropriate hardware and software. They also control relays, solenoids, valves, etc., up to their maximum output current.

The oscillator generates a sine wave of a fixed frequency. This signal is used to drive the coil. The coil in conjunction with the ferrite core induces an electromagnetic field. When the field lines are interrupted by a metal object, the oscillator voltage is reduced proportional to the size and distance of the object from the coil. The reduction in the oscillator voltage is caused by eddy currents induced in the metal interrupting the field lines. This reduction in voltage of the oscillator is detected by the detecting circuit. In standard sensors, when the oscillator voltage drops below a present level, an output signal is generated. OPERATING VOLTAGES Most Altech Inductive Proximity Sensors are available in DC (10-30. VDC), AC (90-250VAC). Please refer to each product specification page for specific operating voltages. OUTPUT CURRENT Altech offers a range of IPS's with different output ratings from 5mA to 500mA. Please refer to each product specification page for specific output current. OUTPUT CONFIGURATION Outputs may be Normally Open (NO) or Normally Closed (NC). DC Inductive Proximity Sensors are 3-wire. A 3 -wire DC sensor can be a NPN or PNP output transistor. If the output load is connected to the negative power source then a sensor with a PNP output transistor is required. A PNP sensor is also known as a source sensor. If the output load is connected to the positive power source, then a sensor with a NPN output transistor is required. A NPN sensor is also known as a sink sensor. Please see Fi g u r e 3 for PNP and NPN SENSOR CONFIGURATION electronic output circuits. AC Inductive Proximity Sensors are 2-wire devices, except when using a sensor with a metal housing where a third wire is available for connection to system ground. HOUSING MATERIALS Altech Inductive Proximity Sensors use a variety of metallic housing materials. Please refer to each product specification for specific information on housing materials. CONNECTIONS Altech offers Inductive Proximity Sensors that feature either 2 meter fixed PVC cable or a variety of quick disconnects. All quick disconnect models require an optional matching cable assembly. Custom cable lengths and material choices are also available. For more information, please refer to each product specification or the cable assemblies section on page 26-31. FLUSH MOUNT AND NON-FLUSH MOUNT Flush Mount sensors are sometimes called Shielded or Embedded. A metal band surrounds the sensing head which contains a coil wound around a ferrite core as in Fi g u r e 4. The resulting electromagnetic field is directed in front of the sensor face. Flush sensors have a narrow sensing field which may be desirable in certain applications. In a Non-Flush (Nonshielded or Non-embedded) sensor; Fi g u r e 4, there is no metal band and the resulting electromagnetic field lines are much wider than the sensor face. NonFlush sensors have a larger sensing distance than Flush sensors. OTHER CONSIDERATIONS: SENSORS IN SERIES AND PARALLEL Sensors may be wired in series or parallel.

TOLERANCES ACTIVE FACE ASSURED OPERATING RANGE 0.9 Sn ≤ Sr ≤ 1.1 Sn TARGET Sn REFERENCE AXIS .81 Sn ≤ Su ≤ 1.21 Sn Sa Su includes temperature, voltage & Mfg. tolerances PROTECTION (Electrical) Most of the Inductive Proximity Sensors Altech offers have short circuit, overload, reverse polarity, and wire break protection. Please refer to the Technical Glossary pages 32-33 and the product specification for more information. PROTECTION (Sensor Housing) All Altech sensors are rated in accordance with IEC Publication 529, which describes degrees of protection that enclosures or sensor housings are designed to provide, the degree of protection is indicated by two letters (IP) and two numerals for additional information see the product specification and page 34. All Inductive sensors meet the following shock and vibration requirements: 30gʼs/11ms, and 10-55 Hz/mm. SENSING DISTANCE There are several sensing distance definitions used in industry. The nominal sensing distance (Sn), is the conventional quantity to designate the operational distance. It is specified in the ordering pages, and does not include variations in production tolerances, supply voltage tolerances, and ambient temperature tolerances. A standard target used to specify sensing distance is a square piece of mild steel having a thickness of 1mm (0.04 in.). The sides of the square are equal to the diameter of the circle inscribed on the sensor face or three times the rated operating distance Sn, whichever is greater. The assured operation distance (Sa) is the smallest useful sensing distance which guarantees operation under variations in temperature, voltage and manufacture. It is given as 81% of Sn.
