MES 25 cable

Product catalog summary

Description: The MES 25 is an optical encoder available in shaft or hollow shaft configurations for various motor shaft sizes. It provides two differential sinus and cosinus output signals for counting and direction information, along with an index channel offering one pulse per revolution. The resolution is determined by counts per revolution (CPR). Power and signals are delivered via a shielded cable.

Performance Features: The encoder is compact, measuring 28.0 mm in diameter and 31.8 mm in length, and supports quick assembly. It features a three-channel differential line driver output with a 1Vss differential output type, powered by a 5 VDC supply with a maximum output drive capability of 20 mA. The resolution options are 250 or 256 CPR, with a maximum shaft diameter of 6.0 mm. It operates within a temperature range of -20°C to +85°C and a frequency of 500 kHz. The encoder complies with the EU directive 2011/65/EU (RoHS) and has a protection class of IP65.

Recommended Operating Conditions: The encoder requires normal handling precautions to avoid ESD damage. It operates with a supply voltage of 4.5 to 5.5 VDC and a supply current of 35 to 65 mA without load. The load capacitance is 100 pF, and it can handle a count frequency of 500 kHz. The operating temperature range is -20°C to 85°C, with humidity exposure up to 90% RH non-condensing.

Mechanical and Electrical Notes: The encoder allows a maximum axial shaft play of 0.1 mm and radial shaft play of 0.02 mm. It uses M3 mounting screws and has a pitch circle diameter of 36.0 mm. The shielded cable is a twisted pair with tinned ends, and the total weight is 60 g. The moment of inertia for the hub with the code wheel is 13.0 gcm². The maximum mechanical speed is 10,000 rpm.

Electrical Interface and Pin-out: The document provides a pin-out description and signal form details. Misuse or operation outside specified conditions voids the warranty. PWB encoders GmbH reserves the right to make changes to products and datasheets.

Ordering Information: The document includes an ordering code and notes that the information is restricted and may be updated. Users are responsible for ensuring their application meets specifications.
