M12-Handle

Supported Applications

The Omega M12 Handle series provides a heavy-duty, handheld probe system designed for temperature measurement applications requiring rapid sensor interchange. The handle facilitates the quick connection and replacement of sensing elements in the field without tools by allowing the M12 connector to slide through the housing.

Handles are compatible with specific OMEGA sensor families:

• TH-21A Series thermistors
• PR-21A and PR-25AP Series RTDs
• M12 Series thermocouples

Operating Conditions & Performance

The M12 Handle is constructed from High-Impact Nylon. The maximum handle temperature rating is 99°C (210°F). While the series supports various probe insertion lengths and diameters, specific process pressure ratings, burst pressures, or vibration/shock specifications are not defined in the source documentation.

Configuration Options

The series offers two primary handle configurations distinguished by compatible probe diameter:

• M12-HANDLE-A: Probe handle for 1/8" (3 mm) M12 probes.
• M12-HANDLE-B: Probe handle for 1/4" (6 mm) M12 probes.

The handles feature an overall length of 108 mm (4.25 in), a body diameter of 29 mm (1.125 in), and a cap diameter of 13 mm (0.5 in). The total assembly length is listed as 127 mm (5 in).

Compatible Accessories

The series supports integration with various probes, cables, connectors, and handheld meters:

• RTD Probes: PR-21A-3-100-A-1/4-0600-M12-1 (Pt100 Class A, 1/4" diameter), PR-21A-3-100-A-M6-0260-M12-1 (Pt100 Class A, 6 mm diameter).
• Thermocouple Probes: M12KIN-1/4-U-12-A and M12KIN-1/8-U-12-A (Type K ungrounded).
• Cables & Connectors: RTD PVC 24 AWG stranded cables with M12 straight socket connectors; Type K thermocouple flat pin male connector (SMPW-K-M); RDXLSD-CONN for handheld meters.
• Meters: HH11B single-input meter and RDXL4SD 4-channel digital thermometer with SD card capability.

Key Product Differences

The primary distinction between the two stocked variants is the probe diameter accommodation. Model M12-HANDLE-A accepts probes with a 1/8" (3 mm) diameter, while model M12-HANDLE-B accommodates larger 1/4" (6 mm) diameter probes. Both models utilize an electrical connection via an M12 connector and share identical housing dimensions and material composition.
