XSZ PROXIMITY SENSORS
SN04-N 18 x 18 x 36 Non-shielded Proximity Sensor
A non-shielded proximity sensor range for magnetic-metal targets, with DC NPN, DC PNP, DC two-wire, and AC two-wire choices.
SN04 non-shielded sensing choices
The XSZ SN04-N is the NPN normally open model in the 18 x 18 x 36 non-shielded series. The filled model matrix also provides NPN and PNP NO, NC, and NO+NC choices, plus DC two-wire and AC two-wire NO and NC choices.
The source lists a 5 mm +/-10% sensing distance, a 0-4 mm setting distance, and an iron 18 x 18 x 1 mm standard detection target. It identifies magnetic metal as the detectable target and notes that sensing distance decreases with non-magnetic metal.
