0156 DIGISPEC PROXIMITY/ZERO SPEED H SENSOR SIGNLE OUTPUT, MAGNET ACTUATED PRODUCT DESCRIPTION SPECTEC's Proximity/Zero Speed position sensors are designed to switch in the presence of a low magnetic field. Bi-polar (north and south polar activation) is standard. Uni-polar and Omni-polar activation is also available for higher pulse resolution. Various output options are available and provided to suit all interface requirements. For intrinsically safe versions refer to bulletins: IS160 IS161. SPECIFICATIONS Vs, Supply Voltage 4.0 to 30 VDC at  18 mA Reverse Polarity Protected Output signal is typically ‘Normally High’ except for PNP output which is ‘Normally Low’ Operating Freq.: Lead Wire & Cable Options See Page 2 0156A 0156M 0156M1 .160” Typically  1” using extra strong 5K Gauss mags Rise/Fall Time: Standard: 0 to ~20 kHz (for precision position applications) High Speed: 0 to ~100 kHz (for high speed only) Temperature Range: *May be reduced based on configuration *May be reduced based on configuration 300 Series S.S. Housing & Face Solid Epoxy Encapsulation See Page 2 All have Gold Plated Pin Contacts Lead Wires & Assignments: 2TE: PVC 22-24 AWG (105°C) 3TE: TFE 22 AWG (150°C) Red: Supply (+) Black: Common (-) White/Green: Signal Bare: Cable Shielding OPTIONS Custom configurations, special materials of construction, temperature probes (NTC10, RTD100, or others) are also available positioned near the face or the sensor.
