SICK SW50 High-Temperature Glass Reflector

SW50 is a SICK high-temperature reflector (part no. 1000131): high-temperature reflector, glass, screw connection. The data sheet lists anodised Aluminium / borosilicate glass as material, a diameter of 80 mm, screw-on mounting and an ambient operating temperature of ≤ +300 °C.

Why the SW50 reflector is built for high temperature

A reflector is the passive partner of a retro-reflective photoelectric sensor: the sensor sends a beam, the reflector returns it, and the output changes when an object interrupts the path. Ordinary plastic reflectors soften at modest temperatures, so a glass reflector in an aluminium holder is used where the light path crosses an oven, a dryer or other hot zone.

This version is catalogued by SICK in the group: special reflectors. The sensing range of the sensor you pair it with is specified against its own reference reflector, so a different reflector changes the operating reserve; confirm the range in the sensor data sheet and leave margin for dust and heat shimmer.

Technical specifications

Type code SW50 and part number 1000131

The type SW50 is a short code for this glass reflector; the number in it should not be read as a dimension, so rely on the data sheet values. The part number 1000131 is the safe way to identify this item. Other SICK reflectors, including plastic types, have other codes and much lower temperature ratings.

Fitting and selection notes

The data sheet gives a dimensional drawing for the screw-on fixing. Keep the glass clean, because dirt cuts the returned light, and allow for thermal expansion of the holder when you tighten the screws. The temperature limit applies to the reflector, not to the sensor, which must be kept within its own limit.

Reflectors are passive, so SW50 needs no cable, power supply or set-up; it only has to sit in the beam of a compatible retro-reflective sensor. Before ordering, check four things: the temperature at the mounting point against the limit in the table, the 80 mm diameter against the beam spot of the sensor you plan to use, the screw-on fixing against your bracket, and the distance range given in that sensor data sheet. If one of these is uncertain, send the sensor type code with your RFQ so both data sheets can be compared.

Documents and quotation

For SW50 the manufacturer’s data sheet (part no. 1000131) is attached as a PDF copy; read it together with your control drawing before you commit to the order. A quotation needs only the part number, the quantity and the delivery destination; the RFQ form takes all three. Related items are listed under Automation Accessories. We suggest a last check of the output type, plug and ratings against your site documents before the order is placed; the data sheet governs.
