FAQ
What objects is BOS 18M-PS-RD21-S4 suitable for detecting?
BOS 18M-PS-RD21-S4 is a photoelectric sensor suitable for presence detection and counting of workpieces, trays and labels. For transparent or highly reflective objects, choose a through-beam or background-suppression model.
Is BOS 18M-PS-RD21-S4 PNP or NPN?
The output type depends on the model. Confirm the PLC input polarity before ordering; PNP and NPN cannot be mixed.
Can BOS 18M-PS-RD21-S4 achieve its nominal sensing distance in practice?
The nominal distance is based on a standard white target. Actual performance is affected by color, surface, dust and temperature, so allow a 20% margin on site.
Is BOS 18M-PS-RD21-S4 in stock?
In stock and available for quotation. Please send us the required quantity and we will confirm current availability.
