The digital mark sensor operates on a supply voltage of 12 to 24 VDC with a tolerance of ± 10%. The ripple is limited to 10% or less. It has a sensing range of 10 ± 3 mm (0.394 ± 0.118 in) and a spot size of 1 x 5 mm (0.039 x 0.197 in). Output 1 is a PNP open-collector transistor. It features a plug-in connector type and a 4-digit red LED display. The sensor is IP67 rated according to IEC standards.
