Panduit T031X000FJC-BK P1™ Continuous Label Tape Cassette
The Panduit T031X000FJC-BK delivers industrial-grade terminal block identification for control panels, power distribution systems, and low-voltage installations. This 0.31-inch polyolefin tape cassette produces black-on-white labels engineered for the thermal extremes, vibration, and chemical exposure found in electrical enclosures and equipment racks. Integrators installing access control panels, power supplies, or automation gear rely on this tape width to mark phoenix-style terminal blocks, DIN-rail devices, and wire bundles where space is tight and legibility under service lighting is non-negotiable.
Key Features
- 0.31" (7.9 mm) tape width optimized for terminal block channels and narrow wire bundles
- 25-foot continuous length yields approximately 300+ individual labels per cassette depending on text length
- Polyolefin substrate resists moisture, UV fade, abrasion, and common solvents (isopropyl alcohol, mineral spirits)
- Black thermal-transfer printing on white background ensures high contrast in low-light service conditions
- Snap-in cassette design for tool-free media changes in Panduit P1 handheld label printers
- RoHS-compliant construction meets EU Directive 2011/65/EU for restricted substances
Polyolefin tape construction separates this cassette from paper or vinyl alternatives in three critical ways: it won't delaminate under condensation (common in unheated equipment closets), it resists tearing during wire pulls or re-termination work, and it maintains print permanence when exposed to cable lubricants or cleaning agents used during panel commissioning. The 0.31-inch width is purpose-built for terminal blocks in the 4–10 mm pitch range—wide enough for two-line labels (circuit ID over description) yet narrow enough to fit recessed terminal channels on DIN-mount devices like relay bases, I/O modules, and power distribution blocks. Integrators working to NEC 110.22 identification requirements or UL 508A industrial panel standards will find this tape width covers 80% of control-circuit labeling applications without stepping up to wider, more expensive media.
Deploy this cassette when installing structured cabling demarcation points, security panel field loops, or BMS control wiring where dozens of terminations require unique identifiers. The 25-foot roll supports batch labeling for mid-size projects—a typical 24-zone fire panel installation consumes 12–18 feet of tape once you account for initiating circuits, notification circuits, and power supervision points. Pair it with Panduit's P1 printer for on-site generation of sequential labels (e.g., "LOOP 1-01" through "LOOP 1-24") that match as-built drawings without the lag of pre-printed label ordering. Data center technicians marking patch-panel ports, SAN switch connections, or UPS terminal blocks will appreciate the chemical resistance when labels are exposed to aerosol contact cleaner or fiber-prep alcohol during MAC work.
This cassette ships as a single-unit package; case quantities of ten are available for facilities teams managing multi-building deployments or service companies stocking field vehicles. The P1 tape format is cross-compatible with Panduit's TDP-series desktop printers, allowing office pre-printing when job conditions prohibit bringing a handheld unit into energized panels. Polyolefin's -40°F to +230°F service range covers both outdoor telco cabinets in northern climates and equipment rooms with limited HVAC, while the material's dielectric properties make it safe for use on live terminal blocks during maintenance windows where lock-out/tag-out isn't practical. For integrators who've dealt with vinyl labels that curl off terminal blocks after two years or paper labels that smudge illegible during the first service call, this cassette eliminates repeat truck rolls for re-labeling.
