SMC CDQSB125D (CDQSB12-5D) - Compact Air Cylinder, 12mm Bore, 5mm Stroke
SMC CDQSB125D Compact Air Cylinder — 12mm bore, 5mm stroke, double acting single rod, standard rod end FEMALE thread (no option letter) - distinct from CDQSB12-5DM which has the male rod thread. SMC CDQSB12-5D is a CQS Series Compact Cylinder, Standard Type, Double Acting, Single Rod, with a 12 mm bore and a 5 mm standard stroke. Note the part number parses as bore 12 with stroke 5 (CDQSB12-5D), not bore 125. The D prefix denotes a built-in magnet for auto switch mounting and B is the basic mounting style. With no trailing option letter the cylinder is supplied in the standard configuration with a rod end female thread. Operating fluid is air, proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa, lubrication not required (non-lube), piston speed 50 to 500 mm/s, and ambient and fluid temperature -10 to 70 degrees C without auto switch or -10 to 60 degrees C with auto switch (no freezing). Supplied without auto switch as standard.

CDQSB12-5D Applications
An ultra-short-stroke compact cylinder for precision work where only a few millimetres of travel are needed. The 12 mm bore with 5 mm stroke is well suited to fine clamping, pin locating, small part holding, nozzle lift and micro-ejection on electronics assembly, test rigs and packaging machinery. The shallow square body keeps the whole actuator inside a very tight envelope. The standard rod end female thread lets a stud or tooling tip be threaded straight into the rod, and the built-in magnet supports flush auto switch mounting for position sensing.
