Incremental Encoders

Incremental encoders are used to very precisely measure position or speed. We supply both optical and magnetic Bei Sensors encoders, from standard to customized versions. Whether you are looking for a redundant encoder with double electronics, simply two or three encoders in line, encoders with a mechanical overspeed switch, a special stainless steel encoder or a fully customized solution, Aproco has it all.
Various models come with electromagnetic protection (EMI shielding), reinforced bearings and extreme shock resistance, and even explosion-proof versions (ATEX of UL, CEN, MSHA for export) are an option.

Our encoders offer a variety of connecting options, which means that they are suitable for your application; M23 connector, PVC cable, PUR cable, Terminal box and 4 pinouts solenoid valve connector for the overspeed version. The maximum resolution is 288,000 pulses per rotation. Bei Sensors supplies encoders with a blind shaft, through shaft and solid shaft, as well as compact 30 mm versions and robust versions up to 200 mm. All industrial standards are available: TTL, HTL, Sine/Cosine for incremental encoders and analogue, parallel, SSI, RS232, PWM or Fieldbus (CANopen, Profibus & DeviceNet) for absolute encoders.
Our manufacturing capacity enables us to offer both metric and imperial versions (NEMA). We can supply encoders for which you can effortlessly program the number of pulses per rotation (PPR) yourself, and we even supply wireless solutions with the SwiftComm wireless industrial sensor interface.


Aproco Drive Technology - Electic Motors

We specialise in NEMA and IEC electric motors (NEMA often for export to the USA, 50 and 60 Hz / UL / CSA / AC-DC), special high-precision (SIL3 / PLe) and/or heavy-duty encoders, earthing resistors and industrial connectors. Aproco supplies an extensive range of standard products from stock and manufactures customised products for (heavy) industrial, maritime and special project applications.

If you need to replace an electric motor or need a fast solution for a new project or due to expansion, Aproco is your partner. We can supply you with identical products or equivalent models (Also if you only need one custom motor or generator). The A-brands which we distribute globally complement every possible product range. Aproco is both an advisor and a supplier in the field of electronic drive technology.
