Vibration Resistance: ≤ 100 m/s²
Protection Class: IP65
Operating Temperature: -20 °C to +70 °C [-4 °F to +158 °F]
Weight: Approximately 0.025 kg [0.055 lb]

Output Signals: The encoder provides various output signal configurations, including A + B + Z and their complements.

Ordering Code: The encoder can be customized using an ordering code that specifies:

Group Function (IS)
Basic Series Number (240)
Shaft Size (3 to 6 mm)
Mechanical Option (None)
Connection Type (2 m or 4 m Cable)
Connector Location (Axial or Radial)
Output, Supply Voltage (TTL, 5 VDC or Push-Pull, 8-30 VDC)
Resolution (1 to 1024 ppr)
Output Signals (A + B + Z, etc.)

Special functions and designs are indicated by a code (Sxxx).

Connection and Accessories:

Connection Function: Includes GND, Vcc, A, B, Z, and their complements with specific cable color codes.
Accessories: Includes couplings (bellow, spring, precision) and clamping claws for mounting.
