Product Description

ECVS-200 Dual Channel Eddy Current Speed Sensor
for Railway Applications, compliant with EN 50155

Technical information

General
Function	The speed sensors ECVS-2xx.xx SHx are suitable, in conjunction with
	an Aluminium pole wheel (or other conducting, non-magnetic metal) for
	generating two nominally 90° phase shifted square wave signals
	indicating the rotary speeds and the direction of rotation.
Technical data
Supply voltage	Nominal 15VDC (8 VDC to 30 VDC), protected against reverse polarity
	and transient over voltages
Signal output	•  2 phase shifted square wave signals, output 1 (S1) and output 2 (S2)
	and direction output.
	•  Duty cycle 50% ± 25%
	•  Phase shift 90° ±40° (on request ± 25°; target specification needed)
	•  Push-pull outputs : Imax = ± 30 mA
	o Output voltage HI (for I = Imax): UHI > Usupply - 1.5 V
	o Output voltage LO (for I = Imax): ULO < 1.5 V
	•  The outputs are short circuit proof and protected against reverse
	polarity.
Current consumption	Max. 30 mA (without load)
Frequency range	Up to 20 kHz
Electromagnetic
compatibility (EMC)	compliant with	EN 50155
Protection class	•  Sensor head: IP68
Shock & Vibration	compliant with	EN 61373 Cat.3
Operating temperature	•  Sensor head: -40° ... +120°C
	•  Cable: -40°C to +150 °C for the standard cable type 824L-36622
Requirements for pole wheel	Aluminum toothed wheel (other non-magnetic material on request)
	Optimal performance with
	• Rectangular gear tooth Module 3
	• Tooth width ≥ 15 mm
	• Valley deep ≥ 3 mm
	• Side offset < 1 mm
	• Eccentricity < 0.1 mm
Air gap between sensor housing and	Module 2	0.2 … 1 mm
pole wheel (depends on the pole wheel	Module >=3	0.2 … 1.5 mm
shape)
Insulation	•  Housing and electronics galvanically separated (500 V/50 Hz/ 1 min)
