ENVIRONMENT-FREE SEALED P6 SEALED LIMIT SWITCHES SEALED AGAINST IMMERSION & CORROSIVE ATMOSPHERES P6 series switches are sealed against immersion and corrosive atmospheres. These switches are designed for rugged duty both mechanically and electrically. A one-piece stainless steel housing, sealed at the plunger with an O-ring seal and at the base with a glass-to-metal header provides true environment-free sealing to comply with MIL-PRF-8805/39, MIL-PRF-8805/40, MIL-PRF8805/43 and MIL-PRF-8805/100. Most case parts are grounded for EMI reduction. The P6 series is available with roller plunger styles for cam or slide actuation and pin plunger for in-line actuation. Contact factory for additional designs. P6 series features the OTTO B2, B3 or B5 series snap-action basic switch. High contact pressure and unique contact design provides low contact resistance for low level switching as well as full rated service. * * * * * * * Complies with MIL-PRF-8805 sealing One-piece housing Sealed at plunger with O-rings Sealed at base with a glass seal EMI reduction construction Choice of pin or roller plunger Choice of axial or radial leads Specifications Subject To Change Without Notice LIMIT SWITCHES Features: Cross section example of OTTO P6-24XXX series. www.ottoexcellence.com 45 P6 LIMIT SWITCHES SEALED LIMIT SWITCHES FEATURING OTTO B2 & B3 SERIES BASIC SWITCHES Style A Pin Plunger Radial Leads Style B Roller Plunger Radial Leads Style C Pin Plunger Axial Leads Style D Roller Plunger Axial Leads 46 OTTO Full Line Catalog Specifications Subject To Change Without Notice P6 SEALED LIMIT SWITCHES LIMIT SWITCHES FEATURING OTTO B2 & B3 SERIES BASIC SWITCHES Electrical Life: 25,000 cycles Low Level Life: 25,000 cycles Contact Resistance: Per MIL-PRF-8805 50,000 feet @ 28VDC Operating Force: 6.0 lbs. to 12.0 lbs. standard.
