Bus termination resistor, termination resistor for PROFIBUS-DP applications, 5-pin, inverse coded, active, M12 × 1 plug to 7/20,3 cm ( 8 inch ) plug, 7/20,3 cm ( 8 inch ) plug for voltage supply, protection class: IP67 (screwed), temperature: -40.+75 °C, Note: This is an active termination resistor. Active termination resistors are more stable than passive termination resistors and are likely to improve performance when higher baud rates are used.
