Specifications
Note: In consideration of vibration and other environmental and mounting conditions, the sensing distance values for the E3L-2RC4 are
very conservative. If these conditions can be minimized, longer sensing distances are possible. Please see excess gain and operating
range curves for more accurate sensing ranges.
