Schlegel Elektrokontakt BFIK Switching Function: Maintained Travel: 3 mmContact Type: Screw Connection 2.5 Mm?…

The Schlegel Elektrokontakt BFIK (SKU: BFIK) is a maintained industrial selector switch designed for precise control in automation, machinery, and control panel applications. This unit features two Normally Open (NO) contacts constructed from AgNi (Silver-Nickel) for high conductivity and extended service life. The BFIK utilizes a robust screw connection system compatible with conductor cross-sections from 0.34 mm² to 2.5 mm², secured with a recommended torque of 0.4 Nm for reliable electrical contact under vibration and mechanical stress. With a 3 mm actuation travel, the switch provides precise operator feedback while maintaining a mechanical service life of 1 million switching cycles. Electrical performance meets IEC/EN 60947-5-1 standards with a rated insulation voltage (Ui) of 250V AC and 300V DC. For AC15 applications, the BFIK supports a rated operating voltage (Ue) of 240V with a rated operating current (Ie) of 1.5A. In DC13 applications, it handles up to 250V with Ie ratings of 0.2A, 0.4A, 1A, or 2A depending on configuration. The switch demonstrates low contact resistance (<20 mΩ new) and minimal bounce time (<10 ms), ensuring clean signal transmission even at low voltages (minimum 5V) and currents (minimum 1 mA under laboratory conditions). Operating temperature range spans from -30°C to 70°C, with storage capability from -50°C to 85°C. The BFIK is rated IP20 for basic protection against solid objects, making it suitable for indoor control panel installations. The maintained switching function ensures the contact remains in its actuated state until manually reset, providing stable control signal retention in machine operation sequences.
