PMIS3 POSIMAG® Magnetic Scale Position Sensor Very compact sensor for industrial applications Sensor head PMIS3 • Non-contact, no wear • High velocity • Robust shielded metal enclosure • Protection class IP67 • Incremental encoder output A/B/Z • Signal processing as usual with encoders • Reference pulse and end position signal • Indicator for velocity/position errors A POSIMAG measuring system consists of the sensor head PMIS3 and the magnetic scale PMIB3 with the same magnetic period. Speciﬁcations Output Excitation voltage Excitation current Magnetic period of the sensor Guided spacing between sensor and mag. scale (xz) Side tracking tolerance of the sensor Linearity (sensor with mag. scale PMIB3) Repeatability Resolution with ext. times 4 counting mode [µm] Max. velocity with fp=50 kHz [m/s] (20 kHz: x 0.4; 10 kHz: x 0.2) Incremental encoder output A/B with differential push-pull output, TTL/RS422 or HTL compatible 10 ... 30 VDC or 5 VDC ±5 % 50 mA to 300 mA, depending on pulse frequency, cable length and load 2 mm 5 mm 0.1 ... 0.8 mm 0.1 ... 2 mm ±1 mm ±1 mm 15 µm ± 40 µm/m 30 µm ± 40 µm/m ± 1 digit ± 1 digit 5 10 20 50 10 25 50 125 0.8 1.6 3.2 8 1.6 4 8 20 Order code PMIS3 PMIS3 — — — KHZ— — www.DataSheet4U.com Model name Magnetic period 20 = 2 mm / 50 = 5 mm Resolution (in µm) with times 4 counting mode Mag. period 2 mm: 5 / 10 / 20 / 50 Mag. period 5 mm: 10 / 25 / 50 / 125 Max. pulse frequency (in kHz, standard 50 kHz) 50 / 20 / 10 Output HTL = HTL output with excitation 24 VDC, output 24 V TTL = TTL output with excitation 5 VDC, output TTL/RS422 TTL24V = TTL output with excitation 24 VDC, output TTL/10 mA Reference pulse/ end position signal/ status signal Z0 = A/B w/o reference pulse / Z1 = A/B with reference pulse Z Z2 = A/B with end position signal / *Z3 = A/B with reference pulse and status signal (Option Z3 only for non-diferential output, single ended) Cable length (in m, standard 2 m) Connection S = Cable output, open end P = Connector D-sub, 9 pin, at the cable end Order example: PMIS3 - 50 - 25 - 50KHZ - HTL - Z1 - 2M - S 6 CAT-PM--E-04 Tel.: 08123/986-0 Fax: 08123/986-500 www.asm-sensor.com — M— ASM GmbH 1 page PMIB3-ST POSIMAG® Magnetic Scale Magnetic scale PMIB3-ST for Position Sensor PMIS3 • Easy splicing • Resistant to moisture and many ﬂuids • Extensive ruggedness against dust, chipping etc. • Magnetic scale with stainless steel base The magnetic material is magnetised in defined and even dis- tances and works as a solid measure. Reference marks can be user defined in 4 mm resp. 10 mm steps. The magne- tic scale retains its firmness by means of a spring steel base (stainless steel strip CrNi 17 7). Speciﬁcations Solid measure Plastic bounded ﬂexible permanent magnet Base material Stainless steel CrNi 17 7 / PE Masking tape Stainless steel (non magnetic) Measurement ranges e.g. 100 ... 2500 mm (up to 50 m on request) Width 10 mm +0.1 mm / -0.2 mm Thickness (with masking tape) 1.7 mm ±0.1 mm Magnetic period 2 mm 5 mm Linearity at 25°C up to 30 m up to 50 m ±40 µm/m ±80 µm/m ±40 µm/m ±80 µm/m Reference mark (zero pulse) max. every 4 mm max. every 10 mm Measurement range must be divisible by 4 must be divisible by 10 Linear thermal expansion coefﬁcient 11 x 10-6 / K Operation temperature -10 ...+70°C An unmagnetic masking tape made of stainless steel is available (accessories). The magnetic scale is ﬂexible and can be glued to the surface of a cylinder with a minimum radius of 100 mm and used for angular measurements.
