Frequently Asked Questions for AS ONE O&M Heater 1-1177-01 Silicone Rubber Heater Sheet (250 mm × 50 mm):

1. What is the AS ONE O&M Heater 1-1177-01?

This product is a flexible silicone rubber heater sheet sized 250 mm × 50 mm. It embeds nickel–chrome resistance wire inside a high-temperature silicone matrix to deliver rapid, uniform surface heating for laboratory and industrial applications.

2. What are its key features?

Uniform heat distribution across the entire 250 × 50 mm area

Thin and flexible profile (approx. 1.5 mm thick) conforms to curved or flat surfaces

High power density (typically 0.8–1.0 W/cm²) for fast warm-up

Operating temperature range from –60 °C up to +250 °C

Electrical insulation resistance ≥ 5 MΩ and dielectric strength ≥ 2 000 V (5 s)

Built-in end-of-line wiring for easy connection to controllers

3. What are the detailed specifications?

Clean and dry the application surface; remove oils or contaminants.

Affix the heater sheet using high-temperature silicone adhesive or specialized heat-resistant tape.

Connect the two lead wires to a PID controller or on/off thermostat rated for the chosen voltage.

Ensure proper grounding of the heater’s metal backing or housing.

Optionally attach a K-type thermocouple or PT100 sensor directly to the heater surface for closed-loop control.

Use a PID temperature controller: set your desired setpoint and tune PID parameters (P, I, D) for stable response.

For simpler applications, an on/off thermostat with hysteresis control can maintain safe operation.

Always place the temperature sensor as close as possible to the heater-surface interface for accurate feedback.

6. What maintenance and cleaning are required?

Always power off and allow the heater to cool before handling.

Wipe the silicone surface with a soft cloth; use mild soap if necessary.

Avoid solvents or harsh chemicals that may degrade the silicone.

Inspect for cuts or abrasions periodically; replace if the internal wiring is exposed.

7. What troubleshooting tips should I know?

Heater does not warm up: verify incoming voltage, check fuse or circuit breaker, measure resistance of the heater (matches datasheet value).

Temperature overshoots or oscillates: retune PID parameters or switch to a controller with shorter cycle time.

Uneven heating: ensure full surface contact and remove any air gaps under the heater.

Physical damage (tears, exposed wire): discontinue use immediately and replace the heater.
