Status: In production
Brand: Panasonic
Product: Non-contact safety door switch (coded, series connectable)
Safety level: Category 4, PL e, SIL 3
Coding level: low code (SG-P10□) or high code (SG-P20□)
Operating distance: Sao (OFF→ON) 5 mm, Sar (ON→OFF) 15 mm

Series connection: up to 30 units (1 standard + 29 sub)
The Panasonic SG-P is a non-contact safety door switch that uses weak radio waves (125 kHz transponder) as its detection principle. It meets Category 4, PL e to ISO 13849-1:2015 and SIL 3 to IEC 61508 and IEC 62061, and conforms to IEC 60947-5-3 and ISO 14119. Two coding levels are offered: high-code models (SG-P20□) correspond to ISO 14119 high level coded actuators and prevent intentional deactivation; low-code models (SG-P10□) require no pairing. The body is available as compact type (-10) or visible type (-20), whose actuator lets the indicator light pass through.
The standard unit (-M-P PNP or -M-N NPN) provides 2 OSSD outputs, max. 100 mA; sub units (-S) cascade from the standard unit, allowing up to 30 units in series without a dedicated controller. Response time for a single unit is 100 ms or less ON→OFF; with multiple units 5 ms is added per additional unit. The indicator of the switch on an open door lights red while all other switches flash green. On high-code models pairing takes 3 seconds by bringing the body close to the actuator and switching on power. SG-PK-M1 and SG-PK-M2 maintenance actuators are available separately.
