WG Wiegand Sensor Selection Guide

Product catalog summary

Overview: This document provides a selection guide for Wiegand sensors, detailing their specifications and typical values. The guide is divided into two main categories: Signal Type and Power Type sensors.

Signal Type Sensors:

WG112: Features epoxy potting with a plastic shell and tinned copper hard lead. It operates within a magnetic flux density of 5-10 mT, with an output voltage of ≥1.5 V, pulse width of 12 μs, and an operating frequency of 10k Hz. It has an internal resistance of 800 Ω, dimensions of 12.8×4.5×4.5 mm, and an operating temperature range of -40 to 125℃.
WG113A: Similar to WG112 but with a pulse width of 15 μs and an internal resistance of 1000 Ω. The operating temperature range is -40 to 85℃.
WG214: Uses high temperature resistant soft lead, with dimensions of 12×7.2×8 mm and an internal resistance of 850 Ω. It operates in temperatures from -40 to 125℃.
WG216: Also features high temperature resistant soft lead, with specifications similar to WG214 but requires reference to the datasheet for internal resistance details. The operating temperature range is -40 to 85℃.
WG311: Comes with an aluminum shell and tinned copper hard lead, with dimensions of φ4×11.5 mm and an internal resistance of 1000 Ω. It operates from -40 to 125℃.
WG314 and WG315: Both use heat-shrink tubes and tinned copper hard leads. WG314 has an internal resistance of 650 Ω, while WG315 has 1300 Ω. Both have dimensions of φ3.3×22 mm and operate from -40 to 100℃.

Power Type Sensors:

WG631: Features epoxy potting with a plastic shell and tinned copper hard lead. It operates within a magnetic flux density of 8-12 mT, with an output voltage of ≥5.0 V, pulse width of 14 μs, and an operating frequency of 1k Hz. It has an internal resistance of 270 Ω, dimensions of 24×7×8.2 mm, and an operating temperature range of -40 to 125℃.

Key Considerations: When selecting a Wiegand sensor, consider the operating temperature range, internal resistance, and specific application requirements such as pulse width and frequency. The choice between signal and power type sensors depends on the intended use and environmental conditions.
