0155 DIGISPEC PROXIMITY SPEED H SENSOR SINGLE OUTPUT, MAGNET ACTUATED PRODUCT DESCRIPTION SPECTEC’s Proximity/Zero Speed sensors are designed to switch in the presence of a magnetic of a low magnetic field. Omni-polar (north and south activation) is standard. Uni-polar (single pole activation) and Bi-polar latching (alternating pole activation) are also available. Various output options are available and provided to suit all interface requirements. The standard output is NPN Supply Tracking 0-Vs, provided from a 3k Ohm internal pull-up resistor to a collector, which can sink 25 mA. The output is normally high with no target present. Other output signal options are available; please see Page 2 for details. SPECIFICATIONS Vs, Supply Voltage 4.0 to 30 VDC at 18 mA No Reverse Polarity Protection Standard: 0 to ~20 kHz (for precision position applications) High Speed: 0 to ~100 kHz (for high speed only) + _ Single Leads w/ Strain Relief Option 0155H 0155HB 0155HB Output signal is typically ‘Normally High’, except for PNP output which is ‘Normally Low’ Operating Freq.: .160” Typically  1” using extra strong 5K Gauss mags + _ Shielded Cable Option 0155A 0155AB 0155AM 0155AM8 Temperature Range: 2TE: -40° to 221°F (-40° to 105°C) *May be reduced based on configuration *May be reduced based on configuration Transmit Distance: 300 Series Stainless Steel Housing Solid Encapsulation Epoxy sealed sensing tip 2TE: PVC 26-28 AWG (105°C) 3TE: TFE 26-28 AWG (150°C) Red: Supply (+) Black: Common (-) White/Green: Signal Out Bare: Cable Shielding See Page 2 All have gold plated contacts Lead Wire Assignments: Custom configurations, thread sizes (including metric), special materials of construction, special output circuits (including short circuit protection), temperature probes (NTC10, RTD100, or others) are also available positioned near the face of the sensor. 4/28/2017, REV.3
