XB4A/XB4B 0.4-mm Pitch Board to FPC Connector Low-profile type with a stacking height of 0.9 mm achieves easy operation and high contact reliability. z The low-profile shape ensures the feel of a sharp “click” and a high retention force. z Twist-resistant design allows removal in all directions. z Easy insertion with self-alignment feature. z Double contacts ensure highly reliable contact. z Halogen Free (See note.) Note: OMRON uses the following standard to determine halogen-free construction: 900 ppm max. for Br, 900 ppm max. for Cl, and 1,500 ppm max. for Br+Cl.
