This table contains the dead band values for set point adjustment at 10% and 90% of the selected scale. For adjustable dead band the lower value corresponds to the dead band spring totally released and the higher corresponds to the dead band spring fully tensed. For other set points the dead band value can be calculated by linear interpolation between the values at 10% and 90%. 2015-11-12 1) Design and specifications subject to change without notice Scale www.baumer.com Data sheet A32.07 Page 3 / 5 RPPN4 Industrial pressure switch with high overpressure resistance Dimensions (mm) 125 76.5 = 144 139 = 58 130 5 64 100 45° Pressure range codes: 151 - 152 - 153 - 154 Weight: 6.4 kg 61 Ø 145 64 56 Hex 24 Ø 120 2015-11-12 Design and specifications subject to change without notice G 1/2(M) G 1/4 12 Ø 245 Hex 24 Hex 24 Hex 24 Hex 24 G 1/2(M) Pressure range codes: 171 - 172 - 173 Weight: 7 kg 84 Pressure range codes: 101 - 102 - 103 - 104 Weight: 10 kg www.baumer.com Data sheet A32.07 Page 4 / 5 RPPN4 Industrial pressure switch with high overpressure resistance Ordering details RPPN4 RP Model Industrial pressure switch with high overpressure resistance Approvals Standard version without ATEX approval Sensing element Diaphragm (Viton ®), high overpressure resistance Type of micro switches 1 SPDT standard changeover switch 2 SPDT standard changeover switch 1 SPDT hermetically changeover switch 2 SPDT hermetically changeover switch 1 SPDT ultra sensitive changeover switch 2 SPDT ultra sensitive changeover switch 1 SPDT hermetically, ultra sensitive changeover switch 2 SPDT hermetically, ultra sensitive changeover switch 1 SPDT gold contact changeover switch 2 SPDT gold contact changeover switch 1 SPDT changeover switch, manual reset, opening on raising pressure 1 SPDT changeover switch, manual reset, opening on falling pressure Pneumatic changeover contact, NO Pneumatic changeover contact, NC Process connection G 1/4 female (only pressure ranges 171, 172, 173) G 1/2 male (standard) 1/2 NPT male 1/4 NPT female Pressure range (mbar) Pressure range (kPa) -50 ... 0 -5 ... 0 -2 ... 10 -0.2 ... 1 -5 ... 50 -0.5 ... 5 -8 ... 100 -0.8 ... 10 -200... 0 -20 ... 0 0 ... 200 0 ... 20 0 ... 400 0 ... 40 0 ... 1000 0 ... 100 0 ... 700 0 ... 70 0 ... 1500 0 ... 150 0 ... 2500 0 ... 250 Options to be added behind the / (see example below) PN – 4 . xxx / RP PN – 4 Deadband Adjustable Adjustable Adjustable Adjustable Fix Fix Fix Fix Adjustable Adjustable Fix Fix A B C W E F D V M K H J Z Y H 3 6 8 . 101 102 103 104 151 152 153 154 171 172 173 Process connection G1/4 female Process connection G1/4 female Process connection G1/4 female / Ordering example with options RP PN – 4 C 3 . 101 / 0407 _ 9941 Design and specifications subject to change without notice Industrial pressure switch Without ATEX approval Diaphragm Viton® 1 SPDT hermetically changeover switch Process connection G 1/2 male Pressure range -50 ... 0 mbar Option: Mounting on 2" pipe 2015-11-12 Option: Stainless steel tag plate and wire www.baumer.com Data sheet A32.07 Page 5 / 5
