ASM GmbH www.asm-sensor.com MAN-PM-E-14 3 POSIMAG® Instruction Manual Description The sensor head all options. The first option after the model type is the magnetic period (example: PMIS3 - 50 - 25 - 50KHZ - HTL - Z0 - 2M - S; in that case the magnetic period is 5 mm). The orientation of the sensor head related to the magnetic strip must be observed (see mounting of the sensor head). We recommend a quadrature counter (e.g. Agilent HCTL2000) for the exact evaluation of incremental signals. An edge-sensitive up/down counter is not suitable. 4 [.157] 7 [.274] R 10 [.394] 10,2 [.402] Xz 17 [.669] 38 ] 15,2 [.600] [.1 4 [.157] 3, 5 25 [.984] PMIS3 & PMIB3 Statussignal Status indicator dx Bending radius (see page 5) Minimum Minimaler bending Biegeradius radius 50 mm [1.969] Me aktimeasurement er Berei Active range Referenzmarke Reference mark Ø5,2 [.205] Dimensions in mm [inch] 35 [1.378] 42 [1.646] * = Position tolerance of the active measurement range: dx = ±1 mm The magnetic strip / magnetic wheel The first option of model name of the magnetic strip is also the magnetic period.

Keep a safe distance to magnetic clamps and other magnetic fields! The accuracy of magnetic strips and pole wheels will be reduced by by low magnetic fields. Keep a safe distance to ferromagnetic materials! Especially magnetic strips and pole wheels may have mutual interaction. These parts shouldn´t touch each other and must not be stored in direct contact. Magnetic strip The magnetic strip must be mounted evenly on the mounting surface ensuring that it is perfectly level and free of bumps. It must also extend the measuring range by 20/25 mm at each end. Note: In order to achieve an optimum adhesion, the mounting surface should first be cleaned of undesirable substances such as oil, grease, dust etc. The surface should also be dry, and contact pressure of the magnetic tape to the surface be as high as possible. The optimum temperature in dry rooms is between 20 and 30 °C. To fix longer magnetic strips it is advisable to remove the protective plastic for a short length and fix one end onto the surface. Then align the rest of the magnetic strip and remove the protective film step by step while pressing the strip to the surface simultaneously. Procedure: 1. Clean the mounting surface carefully 2. Remove the protective plastic film from the adhesive side of the magnetic strip 3. Mount the magnetic strip with the magnetically active (dark) side upwards 4. Clean the surface of the magnetic strip carefully 5. Remove the protective plastic film from the masking tape 6. Mount the masking tape onto the magnetic strip, exactly matching to the magnetic strip at both ends Mounting hint The simple mounting method described above is suitable only for protected environments. The optimum protection is given by mounting the magnetic strip in a groove of a size that the magnetic strip can be embedded completely. ASM GmbH www.asm-sensor.com MAN-PM-E-14 9 POSIMAG® Instruction Manual Mounting (continuation) Magnetic strip in low profile Mounting the magnetic strip in the low profile PMFP is recommended if a suitable mounting surface (see previous page) is not available. The low profile is sold by the meter (max. length 3 m). Separate profile rails can be connected in any order using the connecting pins PMP-VS1. Some additions must be observed for a customer´s pre-cut of the used magnetic strip and the masking tape PMAB: Model of magnetic strip Without reference/ end position marks With reference marks (option R1, R2) With end position marks (option E1, E2) Pre-cut length of masking tape/ profile rail Measurement length + 40 mm Measurement length + 40 mm Measurement length + 50 mm Procedure: 1.

Remove the protective plastic film from the adhesive side of the magnetic strip (possibly a shorter length first) 4. Mount the magnetic strip with the magnetically active (dark) side upwards (check the position of reference or end position mark(s) if existing) 5. Clean the surface of the magnetic strip carefully 6. Remove the protective plastic film from the masking tape (possibly a shorter length first) 7. Mount the masking tape onto the magnetic strip, exactly matching to the magnetic strip at both ends 10 MAN-PM-E-14 www.asm-sensor.com ASM GmbH POSIMAG® Instruction Manual Mounting (continuation) Magnetic strip in high profile The use of the high profile PMHP in combination with the slider PMGW3 is recommended if a precise guiding of the sensor head above the magnetic strip (within the given tolerances) is not possible. The high profile is sold by the meter (max. length 3 m). Separate profile rails can be connected in any order using the connecting pins PMP-VS1. The end parts PMHP-ES1 must be mounted on both ends. Some additions must be observed for a customer´s pre-cut of the used magnetic strip and the masking tape PMAB: Ausführung Magnetband Without reference/ end position marks With reference marks (option R1, R2) With end position marks (option E1, E2) Pre-cut length of profile rail Measurement length + 120 mm Measurement length + 120 mm Measurement length + 130 mm Procedure: 1.

Secure the cable so that there is no risk of damage by cable tension or other machine parts. Use protecting hose and/or cord grip if necessary. Check for the correct orientation of the sensor head (refer to the picture below). The distance between sensor head and magnetic strip (without masking tape should be 0,1 ... 0,8 mm for a magnetic period of 2 mm resp. 0,1 ... 2 mm for a magnetic period of 5 mm (refer to data sheet). The sensor head must not touch the magnetic strip. The status output signal and the status indicator are activated if the allowable maximal distance or the maximum velocity have been exceeded. The velocity tolerance results from the maximal pulse frequency and the resolution, both indicated at the type label. Vmax[m/s] = (resolution [µm] x 4 x pulse frequency [kHz] / 1000) - 20% Example: Resolution 50 µm, pulse frequency 50 kHz Vmax = (50 x 4 x 50 / 1000) - 20% = 8 m/s ASM GmbH www.asm-sensor.com MAN-PM-E-14 13 POSIMAG® Instruction Manual Mounting (continuation) Electrical installation Informations about electromagnetic compatibility (EMC) • Install the complete unit to meet the EMC standards. The installation environment can affect the function of the sensor head. • Make a separate voltage supply available for the POSIMAG sensor head with consumers with high interference levels. • Use shielded sensor cables. • When sensor is mounted on moving machine parts connect them to protective ground. • Keep sensor cable well separated from power wiring. Use separate conduit or ducts. Connection of the cable shield • T he housing of the sensor head is connected to the cable shield. Depending on the facility and the interference environment an isolated or a conductive mounting is necessary. • We recommend: connect the cable shield at cable inlet of switch cabinet to protective ground and mount the sensor head isolated. • A possible alternative connection is to use a conductive mounting of the sensor head and to connect the cable shield to the protective pround of the switch cabinet. 14 MAN-PM-E-14 www.asm-sensor.com ASM GmbH POSIMAG® Instruction Manual Technical Data Outputs Excitation voltage Excitation current Magnetic period of the sensor Guided spacing between sensor and magnetic tape (XZ) Linearity (sensor with magnetic strip PMIB3) Linearity (with magnetic wheel PMIRX) Repeatability Resolution with ext. 4 times counting mode [µm] Max. velocity with fp=50 kHz [m/s] (20 kHz: x 0.4; 10 kHz: x 0.2) Max. pulse frequency fp Output signals Incremental encoder output with differential Push-Pull output, TTL/24V, TTL/RS-422 or HTL compatible HTL, TTL/24V: 10 ... 30 V DC TTL/RS422: 5 V DC ±5 % 50 mA to 300 mA, depending on the pulse frequency, cable length and load 2 mm 5 mm 0.1 ... 0.8 mm 0.1 ... 2 mm 15 µm ±40 µm/m 30 µm ±40 µm/m ±0.1 ±1 digit ±0.1 ±1 digit 5 10 20 50 10 25 50 125 0.8 1.6 3.2 8 1.6 4 8 20 50 kHz, 20 kHz, 10 kHz (standard 50 kHz) A, A, B, B, zero pulse Z, Z, end position signal E, E, status signal ERR (only with HTL output, single ended) A POSIMAG® measuring system consists of the sensor head PMIS3 and the magnetic tape PMIB3 with the same magnetic period.
