PCLM-FT-PCLM-SMP

Supported Applications

The Omega PCLM Series provides ferrite core connector hardware designed for EMI/RFI noise suppression in measurement circuits. These patented cable clamps are engineered to help reduce electromagnetic and radio frequency interference when used with standard, miniature, or RSC-compatible thermocouple connectors.

Operating Conditions & Performance

The series utilizes Nickel-Zinc Ferrite cores to achieve specific impedance characteristics at high frequencies. According to the specification table:

• PCLM-FT (Standard Size): 120 Ω @ ±20% @ 25 MHz; 225 Ω @ ±20% @ 100 MHz.
• PCLM-SMP-FT and PCLM-SMP-RSC-FT (Miniature Size): 105 Ω @ ±20% @ 25 MHz; 155 Ω @ ±20% @ 100 MHz.

The clamps support duplex wire gauges up to 14 AWG for standard connectors and up to 22 AWG for miniature connector variants. No explicit ambient or process temperature ratings, environmental enclosures, or dimensional specifications are provided in the source documentation beyond impedance values and compatibility lists.

Compatible Connector Types

The series supports specific Omega connector families as documented:

• PCLM-FT (Standard): Compatible with OST, OSTW, HST, HSTW, OGP, HGST, and OTP connectors.
• PCLM-SMP-FT & PCLM-SMP-RSC-FT (Miniature): Compatible with SMP, SMPW, GMP, HGMP, HMP, HMPW, and MTP connectors.

Configuration Options

The series is offered in configurations tailored to connector size and cable type:

• PCLM-FT: Ferrite cable clamp for standard-sized connectors, accommodating up to 14 AWG duplex wire.
• PCLM-SMP-FT: Ferrite cable clamp for miniature-sized connectors, accommodating up to 22 AWG duplex wire.
• PCLM-SMP-RSC-FT: Miniature ferrite cable clamp specifically designated for use with RSC (Remote Sensor Cable) applications.

The documentation notes that both standard and miniature models are shown larger than actual size in illustrations. For twisted shielded wire configurations, the manufacturer directs users to online resources.

Key Product Differences

Variants within the PCLM Series differ primarily by physical size (standard vs. miniature) and intended cable compatibility:

• PCLM-FT-PCLM-SMP family: Includes standard ferrite clamps (PCLM-FT), miniature ferrite clamps (PCLM-SMP-FT), and the RSC-specific miniature variant (PCLM-SMP-RSC-FT).
• PCLM-DTC, PCLM-SMP-RSC: Listed as enabled variants within the series bundle; specific functional distinctions for these part numbers beyond the ferrite clamp description are not detailed in the provided specification table.
