Omron ES1B 60-120C Infrared Thermosensor

Technical Overview

The Omron ES1B 60-120C is a highly reliable, non-contact infrared thermosensor designed to provide an accurate and cost-effective alternative to traditional contact thermocouples. Operating over a temperature range of +60°C to +120°C, it outputs an electromotive force identical to a standard K-type thermocouple, allowing seamless integration with existing temperature controllers. Encased in an M18 threaded ABS resin housing with an IP65 protection rating, it boasts a rapid 300 ms response time. Its non-contact measurement mechanism prevents mechanical deterioration, making it an ideal sensing solution for food processing, packaging, molding, and electronics manufacturing applications.

Industrial Applications

1. Packaging Heat Seal Temperature Regulation

In high-speed packaging machinery, heat sealing jaws and rollers must maintain specific temperatures for airtight seals. The Omron ES1B safely monitors these moving surfaces non-invasively, transmitting real-time data back to the machine's PID controller using its built-in K-type thermocouple equivalent output [1.3].

Problem Solved

Eliminates the mechanical wear and frequent replacements associated with contact thermocouples on rapidly moving machine parts.

2. Food Processing Conveyor Monitoring

During continuous baking or drying processes, organic products move along conveyors where contact sensors cannot be used. The ES1B accurately reads surface temperatures between +60°C and +120°C, ensuring optimal processing conditions without physical interference.

Problem Solved

Prevents product contamination and sensor degradation while ensuring food safety compliance and consistent baking quality.

3. PCB Preheating in Wave Soldering Lines

Before entering the wave soldering machine, PCBs are preheated. The ES1B measures the exact surface temperature of the PCBs non-destructively within its +60 to +120°C range, ensuring they reach the ideal thermal state.

Problem Solved

Averts thermal shock to sensitive electronic components by precisely monitoring preheat temperatures non-invasively.
