Magnetic actuator switches detect the position of a cylinder's magnetic piston without contact — they sit on the outside of the barrel and respond to the piston's internal magnet. Norgren's two switch families cover every modern cylinder: the M/50 round-style family (10 ranges) for all profile, ISO and round-line cylinders with optional flush mounting, IO-Link, ATEX zone 2/22 and UL listed versions; and the QM/TQM block-style family (7 ranges) for high-vibration environments. Both reed (for switching up to 240 V AC / 170 V DC) and solid-state PNP/NPN (for fast PLC inputs with low jitter) options.

Pneumatic proximity switch
Reed is the universal choice — works from 10-240 V AC or 10-170 V DC (M/50 family), no polarity, no PNP/NPN distinction; you switch the actual load directly. Long but finite contact life; slightly slower (a few ms). Solid-state is PNP or NPN specific to the PLC input type, but offers <0.1 ms response, no contact wear, and longer life at high-frequency switching. For modern PLC-driven machines: solid-state. For mixed-voltage relay logic or universal stock: reed.
M/50 switches mount flush on profile cylinders (PRA/802000, PRA/801000, PRA/803000, PRA/822000, PRA/862000) — direct fit, no protruding hardware. For tie-rod versions (RA/802000, RA/801000, RA/803000, RA/8000, KA/802000) the adapter delivered with the switch is used. Roundline and QM/TQM cylinders use the appropriate mounting straps or block clamps supplied with the switch. See the individual switch and cylinder datasheets for fixing details.
If your installation is in an explosive atmosphere zone per ATEX 2014/34/EU. Zone 2 (gas) / zone 22 (dust) → M/50/EXP (solid-state), M/50/IXP (ATEX + IO-Link) or M/50/LXU (reed). Zone 1 / 21 or stricter (zone 0 / 20) — Norgren's M/50 ATEX family is rated for zone 2 / 22 only (Cat. 3G/3D); for stricter zones use an intrinsically safe (IS) isolator with a standard switch and an IS interface. Always check the switch datasheet's specific Ex code (M/50/EXP: II 3G Ex ec IIC T4 Gc X / II 3D Ex tc IIIC T110 °C Dc X; M/50/LXU: II 3G Ex nC IIC T5 Gc X / II 3D Ex tc IIIC T120 °C Dc X).
Auto-configuration: a replacement M/50/IOP automatically loads its setup parameters from the IO-Link master's stored data — no manual setpoint adjustment after a swap. Diagnostics: switching count, runtime hours, internal temperature reported back to the PLC. One cable does both signal and configuration — fewer wires, less termination time. Additional IO-Link features: normally-open / normally-closed switchable, delay mode, installation aid, temperature measurement, responsiveness adjustment, teach functionality. IODD profile downloadable from the Norgren website. Best fit for PLC-driven machines being commissioned for Industry 4.0 / predictive maintenance.
Any Norgren cylinder with the M/... or RA/...M/PRA/...M magnetic-piston code is compatible with the M/50 (flush) or QM/TQM (strap) switches. Non-magnetic cylinders (RA/8000 without /M, RT/57100 without /M) don't have a piston magnet and need a different position-sensing approach (e.g. PSA/802000/F1 with built-in resistive position sensor). Always check the cylinder code for the /M magnetic-piston suffix.
