PKS

(Wire-Draw Encoders)

Features:

  • Fast and simple integration

  • Compact housing

  • Cost-effective design

  • Integrated measuring system

  • Measuring length up to 5 m

  • High resolution

PKS09-ATBM0220

At a glance:

  • Incremental encoders

  • Compact housing (90 x 90 x 90 mm)

  • Encoder integrated into housing

  • Measuring lengths from 2 to 5 m

  • High resolution

  • TTL interface

Benefits:

  • Industrial designed encoder integrated in an aluminum housing makes it less susceptible to external damage, saving time and reducing maintenance costs

  • Extremely precise measurements by eliminating the coupling between the encoder and the mechanism

  • Space-saving installation, since the encoder is directly integrated into the wire draw mechanics.

  • Very precise measurements thanks to high resolution

Performance:

  • Measuring range: 0 m ... 2 m

  • Linearity: ≤ ± 0.7 mm

  • Piston speed: 3.5 m/s

  • Repeat accuracy typ: 3 measuring steps

Mechanical data:

  • Mass: 1.5 kg

  • Measuring wire diameter: 0.6 mm

  • Measuring wire material: Highly flexible stranded steel (PA 12 sheathed)

  • Housing material: Aluminum

  • Spring return force: 5 N ... 6 N 1)

  • Life of wire draw mechanism:: 800,000 cycles 2) 3)

  • Wire acceleration: ≤ 20 m/s²

1)These values were measred at an ambient temperature of 25 °C. 2)There may be variations at other temperatures. 3)At high operating speeds over great lengths,this figure can decrease; at slow oerating speends over short lengths, it can increase.

Electrical data:

  • Operating current: 60 mA (without load)

  • Reference signal: 1/765 measuring steps

  • Maximum load current: 20 mA

  • Initialization time: 40 ms 1)

  • Supply voltage: 4.5 V ... 5.5 V

  • MTTFd: mean time to dangerous failure: 400 a (EN ISO 13849) 2)

1)Valid positional data can be read once this time has elapsed. 2)This product is a standard product and does not constitute a safety component as defined in the Machinery Directive. Calculation based on nominal load of components, average ambient temperature 40°C, frequency of use 8760 h/a. All electronic failures are considered hazardous. For more information, see document no. 8015532.

Interfaces:

  • Electrical interface: 4.5 V ... 5.5 V, TTL/RS422

  • Connection type: Connector M23, 12-pin, radial

  • Encoder: Incremental encoders

Ambient data:

  • EMC: (according to EN 61000-6-2 and EN 61000-6-3)

  • Enclosure rating encoder: IP 52 (according to IEC 60529), Note required mounting position

  • Resistance to shocks: 20 g, 6 ms (according to EN 60068-2-27)

  • Resistance to vibration: 10 g, 10 Hz ... 2,000 Hz (according to EN 60068-2-6)

  • Storage temperature range: -20 °C ... +80 °C

  • Relative humidity ∕ Condensation: 90 % (Condensation not permitted)

  • Working temperature range (encoder): -10 °C ... +70 °C
