Keyence SK-H050 Electrostatic Sensor | Charge, Temp, Humidity Meter

Product Introduction

SK-H050 from Keyence is a hand-held electrostatic sensor. It measures charge potential, temperature, and humidity. The SK-H series suits industrial static control. This unit offers two charge modes: high-precision and wide-range. It helps you find static problems fast. Use it for spot checks and maintenance.

Key specs include ±2 kV high-precision mode and ±50 kV wide-range mode. The sensor also reads 0 to +40 °C and 10 to 85 % RH. It runs on two AA batteries for 8 hours. A Class 1 laser aids alignment. The SK-H050 is active and in production. Last verified: 2026-09.

Installation Guide

Installation is simple. Insert two AA batteries. Press the power button. Select high-precision or wide-range mode. For charge measurement, keep the sensor at the correct distance. Use 25 mm for high-precision. Use 100 mm for wide-range. The Class 1 laser helps you aim. No extra tools are needed. For temperature and humidity, just point and read.

Setup and Maintenance

Setup takes minutes. Turn on the unit. Choose your mode. The display shows charge, temperature, and humidity. Calibration is not user-adjustable. Clean the lens with a soft cloth. Do not use solvents. Replace batteries when the display dims. Store in a dry place. The SK-H050 needs no regular service. It is designed for daily industrial use.

Compatibility Notes

The SK-H050 works as a stand-alone unit. It has a USB 2.0 Full Speed port. You can connect it to a PC for data logging. It does not support external communication expansion.

e PZ-G series. It uses a narrow view reflective design. This cuts background interference on short range targets. The rectangular housing fits tight machine frames. Detection reaches 200 mm. The red LED spot stays about 5 mm at 100 mm. A PNP open collector output drives most sinking PLC cards. The PZ-G101CP uses an M8 connector, so cable routing stays clean and service stays fast.

FAQ

Q: What makes the PZ-G101CP different from a standard diffuse sensor?

A: It uses a narrow view optical design. This limits background reflection and improves short range stability.

Q: Does the PZ-G101CP include a cable?

A: No. It uses an M8 connector. Order the cable separately to match your panel run.

Q: What output type does it provide?

A: It provides a PNP open collector output. Check that your PLC input card sinks current.

Q: How far can it detect a matte white target?

A: Up to 200 mm. Dark or glossy targets reduce this range, so test on site.

Q: Can I mount two units side by side?

A: Yes. Up to 2 units with polarization filters or the automatic different frequency function.

Q: What mounting torque is safe?

A: 0.5 N·m maximum on the mounting hole part. Higher torque can crack the housing.
